Great video. I'd recommend adding a shutoff valve (one-quarter turn ball valve), between the new tee on the auxiliary storage tank, and the (orange) lead line. Then you can close the new valve when you detatch the lead line from the compressor to hold the air in the auxiliary storage tank (actually holds the air in both tank systems) allowing you to retain its functionality as a pressurized portable tank. Plus this eliminates "wasting" the stored air pressure and reduces the time the compressor needs to run to pressurize the system thenext time you attach the auxiliary storage tank (if htere is pressure remaining there). Or, alternately, install a coupler on the new tee on the auxiliary storage tank, and another plug on the end of the (orange) lead line. This means the (orange) lead line will have a plug at each end. Then to disconnect the auxiliary storage tank from the compressor, first back off the regulator valve to 0 PSI, then disconnect the (orange) lead line from the new coupler on the auxiliary storage tank. Again, you'll now be able to use the auxiliary storage tank as a pressurized portable tank. Finally, for safety sake, I'd consider finding a way to reinstall the pressure relief valve on the auxiliary storage tank. Either add a second tee to add another port/fitting for the relief valve, or use a 4-port ("x" or "cross") fitting instead of the tee, to start with. This would add a margin of safety in case the auxiliary storage tank was exposed to (extreme) heat, which might cause the pressure to rise above the tank rating.

[@OneIdeaTooMany]

Or jhe could be ust using a teleprompter but if not, well done

[@sandy7m]

Sorry if this has already been commented on but it is pretty important. You have to install a one way valve between the quick connector and the extra tank. There is a high hazard scenario where a quick connector could be inadvertantly disconnected allowing the total volume of the extra tank to rapidly vent through the unckecked male connector. Alternately, a double action quick connector could replace the standard quick connector. Ideally the quick connector should be changed out for a thread connection system such as NPT or BSP. Hope this helps

[@Universalengineerings]

I thought also like your mind, we have to install Check Valve/ One way Valve to protect Compressor Piston from back pressure from Auxiliary Tank.

[@Jared01]

To correct one thing you said in the video: "The equalized tank pressure between both tanks of the Husky, as well as that auxiliary tank, have an equalized pressure of 125 PSI." That's incorrect. The tanks attached to the Husky are at 125 PSI, however the auxiliary tank, since it's on the OUTPUT side of the compressor, is limited to the pressure set by the output regulator. In this case, the auxiliary tank will be at about 90 PSI. Because of that, the auxiliary tank works more as a buffer tank than it does as a storage tank - it can give bursts of air for tools that use a lot (impact gun is a perfect example), but because the auxiliary tank is regulated by the output (and at the same PSI level as the tool you're using), the tanks on the Husky will drain every bit as quickly as they did before the mod in order to refill the auxiliary tank. In order for the auxiliary tank to help the other two tanks, it does need to be on the unregulated side sitting at 125 PSI. There's two easy ways to fix this: 1. Set the output regulator to maximum, and add a secondary regulator on the auxiliary tank with an output gauge. 2. Remove the drain plug from the Husky tank, thread in a fitting, and add the auxiliary tank connection straight to the Husky tanks. Option number 1 is a bit more expensive, but doesn't have the water issues that option number 2 has (the water from the Husky will be pushed into the auxiliary tank and need to be drained).

[@RealToolReviews]

Yes, I agree......I normally leave the regulator fully open on these small tanks due to pressure drops......so I mis-spoke. You are correct.....the aux tank has the same pressure as the regulated pressure.

[@larrywhite4310]

+Real Tool Reviews what fitting do i need

[@ryanjames170]

either way it did work well,, but i do agree with you there, i am thinking on doing more of what you said to do though with my 10Gal compressor adding a 10 gal extra tank to double my tank capacity for plasma cutting.

[@Der7w]

Can you tell me the way to set the output regulator to maximum and add a secondary regulator on the auxiliary tank with an output gauge please?

[@midnitebo]

You just turn up the regulator dial on the main compressor to the maximum.

[@dandavis1023]

Simple and too the point. No family history and compressor past failures. Good video.

[@RealToolReviews]

Thanks! :)

[@chandiaz7694]

Took your idea and applied it to a Porter Cable 6 gallon pancake tank. The Porter Cable compressor had its days so I’ve removed the compressor and all the valves, gages. Plugged the hole were the gages and regulator was installed with a quick disconnect that was on the gage setup. Now all I need to do is purchase the “T” since I have all other parts you used in this video. Thanks I needed to give my 21 gallon compressor more capacity for air tools I’m using.

[@Lasurge1982]

Wow you made this so easy to follow along with. Straight and to the point . Probably the best video on KZbin for this application. Every other video that I seen the person babbles on about useless irrelevant information other than what I am trying to accomplish and don’t make it easy to follow along. Thank you for not babbling.

[@Leeroy2586]

this guy's got the best tool reviews on KZbin. hands down. he explains everything to a T. if I'm looking for a new tool I make sure and watch his review. he is like the Hickok45 of the tool world

[@RealToolReviews]

+Clint Moberly haha thanks 👍

[@frontxxrunner]

You had me at Hickok45

[@TheMechanicalPhilosopher]

Years ago I made a T like this but with 2 male and one female connectors so that we could connect any two people's compressors together to run the whole job site off of what we independent contractors normally carried. This is also a great reason to collect old compressors, those tanks are valuable. You've got a very nice mic there, no more changing volume/tone.

[@ThePete1891]

So, I did this years ago when painting my pickup. I use one of those Porter Cable 6gal pancakes evdry year. One year, I saved the broken one year, and made an auc tank. What I found is yes, you get twice the capacity, but it takes twice as long to fill. Not good when painting a pickup. I ended up firing up my wheel barrow Emglow, with 5hp Honda. With that the tank will fill while I am painting. What you need is a larger pump. The compressor gets super hot running super longrunning so much longer, and using constant for painting, or impact steady.that is what I found anyway

[@eawhit]

Just wanted to say THANK YOU for making this video. I used your technique to double my system capacity from 10 to 20 pounds for blowing out the sprinklers. Worked fantastic! I’ve probably watched all your videos over the years and learned a lot. Thanks!!!

[@danielfitterer2645]

So a few things. Shouldn't you have the regulator at the end of the supplemental tank? Otherwise your receiving the 125 psi to the tool as that is the static pressure of the line coming out of the supplemental tank. This would be the reason as to why the lug nuts were removed so easily on the second test. Wouldn't it be more appropriate to use the other output from the primary compressor as this is controlled via the regulator?

[@seanpattersonjr7964]

Removing the regular entirely would be best, there is not enough volume to keep the tool running at a working pressure for a long period of time. Removal or the regular allows for peak pressure for longer and less resistance to flow and would make things a lot easier.

[@chuckkolancz4969]

I’m so glad I saw this. Was about to go drop a couple hundred bucks on an air compressor id use once every other month to use my impact. Now I can go spend $60 and get by with the impact a lot better and also have air to keep in the bed of my truck in case my tires get low. Thanks!

[@Boost_Addict]

hands down best video explaining this addon

[@johnnyboy22]

In addition to storage capacity, I think this also showed another important point: Airflow. While the Huskey compressor has pressure, it doesn't flow the air well due to the fittings, lines or regulator being restrictive. The auxiliary tank with the way it was set up flows a lot more air, which you can see with the impact being much more powerful, and the fact that after using the tool it took a few seconds to refill the auxiliary tank. Nice work!

[@johnmcdougald1238]

I did something like that but I installed a ball valve inline on the auxiliary tank so I could also use it to just fill the tank and use it for smaller projects around the house. You get the benefit of the unrestricted air flow and still have the original portability of the tank.

[@robthewaywardwoodworker9956]

Good simple idea to expand capacity. But did anyone mention how good your video is? Great quality and production. Thanks for taking the time to make a video that is easy to watch and listen to. I'll have to check out more of them!

[@damienmikkelsen6056]

BRO! I was about to return my compressor and spend $300 more to get a compressor to run my palm sander for diy auto paint repair. Genius idea. Thank you!!!!

[@Wagonman5900]

I added a ten gallon auxiliary tank to my six gallon compressor. It works just like he says it does. When I plumbed the secondary tank I did add a ball valve to take the tank and add air to tires if I need to. I also used a four way connector instead of T connector for a pressure gauge.

[@RealToolReviews]

Nice job!

[@Wagonman5900]

Thanks. I did find a sticker on the tank that said not use it with tools that require a regulated air source, but I think that was just a suggestion.

[@Valerie10384]

Secondary tank pressure will be the same as the regulated air pressure coming out of the Husky. Not the 125 PSI of the Husky's air tanks. Check valve and ball valve should be in place on the secondary tank.

[@RealToolReviews]

That’s correct, I misspoke.

[@EricDalgetty]

Actually it looks like he connected the additional tank before the regulator so I think all tanks will be at the same pressure

[@ChuckD59]

@@EricDalgetty On my Rolair VT25BIG both those connections are regulated. If this is the same the OP is correct and RTR misspoke, or rather left out the part to open the regulator all the way. Great video though as mine is 6 gallons and I would definitely like to expand it's capacity.

[@firworks]

This is a pretty neat idea and something I've been wanting to do with an old 6 gallon portable air compressor that has a bad check valve. The only thing I would caution people of is to check the duty cycle rating on their compressor. California Air Tools doesn't list one but say not to operate their compressors for more than an hour continuously. If you are using a small portable compressor with a large air tank and using air hungry tools it may be possible to overheat the motor on your compressor so just use some judgement when you try out this trick.

[@dmoore319]

I did mine much simpler and it is still very effective. I kept my portable tank as originally configured with the safety valve etc and attached a 3/8 hose with a standard1/4 in quick disconnect adapter on the output port. I then plugged a 3-way standard disconnect manifold into the output port of my compressor. I connected the portable tank to one of the 3-way ports and my tools to the other two ports. Major difference in tool power and reduced compressor motor running time. I run impact guns, ratchets, and grinders etc with no problem now. Maybe the small output hole on the portable tank is reducing my power slightly, but not enough of a problem to notice. I have a total of 15 gallons now and can still easily transport my tank to fill tires etc by simply connecting a valve stem adapter to the quick disconnect. As a note, in its original configuration, air can flow both ways on these tanks, meaning you can fill it and pull air from the same port and hose. So basically many ways to skin a cat and get the same or similar results.

[@albanianeagle3111]

Just finish assembling it together. Thank you for the helpful video. I did it exactly how you did it here. Thank you

[@wingerrrrrrrrr]

It's good if you have the patience for the longer charge times, but as mentioned at the end, it's not a substitute for a larger compressor, because it doubles the wait time for charging. 5:43 Attaching a 60 gallon tank to it would allow you to do all four wheels at a time, as long as you can have breakfast while charging it up initially.

[@ineedfiles]

i found this out the hard way a few weeks ago with a 8 gallon air compressor and a 20 gallon tank.. it sucked... but i'm gonna try it again with a 20 gallon air compressor and a 25-30 gallon tank this week

[@roadrageburleson]

I did this project myself but added a quick release on both sides of the t fitting so I can disconnect it and move it to the back yard and hook it up to the small compressor in my shed when working out there and not loose any of the stored air in the process. Thanks for the great Idea.

[@philthyphil3324]

Great video, I've been thinking about doing this for a while. But my main concern is for the compressor motor. Won't it have to run much longer to pressurized the extra volume? I think this might be a good way to burn up a motor. I'm just thinking out loud here, I'm really not sure. Either way, I am getting a 60 gallon 3.7 horse for the garage, and will use my 2 horse compressors for the job sites.

[@si98justme1]

A little late to the party here... I had the same concerns, however, when you think about it, the motor is designed to pressurise a completely empty tank (ie a long time), so the topping up cycling will not cause any more strain or heat on the motor, however it will still run for longer each cycle, so wear items like bearings, rings bores etc will see more wear if it were cycling at the same frequency for longer. This is not the case though, as it should cycle less often, though for longer, eg if you double the original tank capacity, it will cycle roughly half as often, but for twice as long, which nets to more or less the same motor run time overall. So in short, it shouldn't cause any additional motor wear, and if it does, it would likely be negligible.

[@ManlyManStuff]

Even later to the party but I'll shine some light on the subject anyway. I actually did some research correlating to this a while back and it's cycles that ultimately kill compressors. So more volume, less cycles, longer life. Cut and dry.

[@Canbechangedtwiceeveryfourteen]

@@ManlyManStuff but now each cycle is twice as long... (even later to the party)

[@jeffbanfieldsflwr3537]

[@matthewbloomfield5580]

Wouldn't you lose the ability to set your tool pressure? I think to do this right you really need a few more fittings: A check valve to allow you to use the tank as a portable tank/remove and not blow air everywhere, a safety blow off, and a pressure regulator. This would allow you to regulate tool pressure properly, plus adding some safety all around.

[@stewartadams5884]

OK I love this concept I have a 26 gallon unit. I wanted to be able to do paint and body work. I didn't have a lot of money, so I waited for someone to throw out a water heater and now I have a 60 gallon water heater tank attached I have the top electrode hole as the intake and the bottom as an out, had I seen this video I would have plugged them both and used this type of set up in the top. I may change it after seeing this. I have considered adding a refrigerator compressor also as an added air pump.

[@dstar3131]

Super presentation. What a very well spoken young man! I want to see you as the spokesman for so many more products!

[@richardjeun]

When I use a Hvlp paint gun, I hook up my 2 gal compressor, 5 gal portable, 30 gal compressor, 29 gal compressor all together. I can keep using air without losing pressure. All three units work together to keep pressure above 90 psi at all times at the dryer. All my compressors are regulated down to 120 psi.

[@wedge999]

I do this slightly differently. Put a manifold with universal couplers off one side of the T fitting on the auxiliary tank This gives you the option to run multiple small tools without swapping your air hose every time you change tools (not always a need but handy). Take a pair of NPT fittings and join them together so that you can link the air hose off of your supply tank/compressor into the auxiliary/portable tank for fast filling. Off the other side of the T-fitting, a pressure gauge with the standard schrader valve so you can still fill it with an air chuck while you're "out in the world". Tip: Always use universal couplers on your hoses so you can connect up to whatever fitting is on the tool you're going to use (Industrial, Automotive, or ARO). I also prefer brass since it usually connects/releases easier.. I keep a short hose with an air chuck and the male-to-male coupler I mentioned with the portable tank at all times.

[@rdsinoklahoma4357]

The auxiliary tank will never exceed regulated pressure as you hooked it up. You need to tap into the tank before the regulator. A good option would be to tap into the drain plug but that wold send all condensation to the auxiliary tank with the air. this may seem like a moot point but if you were say painting at 40 psi it would greatly reduce available capacity.

[@Canbechangedtwiceeveryfourteen]

This!

[@pfmobius]

Great video. My 60 gal died and since I don't need such a large unit any longer I bought the Husky in your video. I would have never considered an expansion tank for more air. Now I'm wondering if I can use to fill my 60 gal. I'm thinking the long run time my dramatically shorten the life of the small husky so now I'm hunting a small air tank. Thanks for the great video and great idea

[@GarlandFarms]

Update?

[@leefhead1]

There are quite a few issues with this, ill put them in a list. 1. with the regulator on the tank set the way it is, the second tank is at a much lower pressure than the first tank, negating a lot of the benefits you're trying to gain. You would have seen this if you added the air pressure gauge back in with another T fitting. You should crank up the regulator and add one at the outlet side of the second tank, or move where the second tank connect to the main tank to before the regulator. 2. although you have a higher capacity, the compressor motor is FAR too small to fill that amount of space, so it will take a lot longer to fill, and lower the motor life span greatly as its not designed to run so long, every time. 3. if you disconnect the air line from the main tanks, it'll blow off all of the air. you should have put an air shut off valve at the tank between the hose and the adapter, as well as have 2 female connectors on the tank, and build a male/male hose. This allows you to close the valve, then disconnect the hose while losing very little air and you can still use the air pig as an even more capable air pig, now that it has a larger orifice to allow quicker movement of air. This would also allow a lot easier emptying of the aux tank. simply close the valve, disconnect the air line at the main tank, then open the valve as little or as much as you want to empty the tank, as quickly or as slowly as youd like. 4. After the costs of the air pig, the adapters, the hose, an extra regulator, shut off valve, and all that+65 time, you could have just sold your too compressor thats too small and bought a properly sized used compressor. With all this in mind, I love your videos. Theyre very informative and have helped me decide on many different tool choices.

[@dtrrtd774]

I actually prefer higher CFM ratings with smaller storage tanks because when an overly large tank is used, it's too frustrating waiting for the tank to charge up from empty. The only thing it would be useful for is a one shot use where you can flip it on, walk away and have breakfast, then come back and get to work. If the work you have to do requires more air than what you stored, you'll have to go for lunch as it charges up again. The compressor output is the driving factor in the ability to work continuously, not the size of the storage tank. Large tanks extend both the work time intervals but at the cost of longer idle periods while waiting for it to charge up again.

[@josephflint19]

This video only tells you how to get stored compressed air where as his problem described needs more cfm

[@alonfn2]

we have this setup on our big 80 gal compressor and use 44 gal surge tank I can usually do 2 sometimes 3 tires before it will kick on

[@mlee6050]

@Finky198 is there a recommended size system for diy stuff as in do car things too, at moment looking at a 14 litre compressor but as it gives great air compression speed at 55db (aiming to try to keep things below 70db where I am)

[@Pro1er]

I have the same setup with a 7 gallon air pig, but I put a quick connector on the hose end of my pig which left me with a fully usable tank. That way the pig is still good for filling tires and running a brad or pin nailer, and I don't have to empty it when I disconnect it from the compressor tanks.

Good idea as i have done it in my house adding 3 11 gallon tanks but I also have 2 compressors with 21 and 26 gallon tanks. Adding tanks can be useful but remember you are running the compressor longer to air up all the extra tanks you add which will shorten the life of your compressor.

[@corynickoleff767]

Wouldn't you want some sort of valve off the lead hose before the "T" ???? You could use the air tank to go blast some brad nails or tank it to air up a tire on the lawn tractor

[@jfortune06]

I did something similar using a Husky 10 gallon aux tank to connect to my 25 gallon super old and cheap compressor which is barely hanging on. I installed a 4-way T so I could have a ball valve with male connector on one end, 10 foot hose with female coupler on the other and a pressure gauge in the middle. This way, I can open the ball valve, connect it to my compressor and fill it up, then close the ball valve and take the tank to another location to fill up tires, or even run a tool for a little while on the stored pressure. Or, I could leave the valve open and use it in series like shown in the video. I just have to be careful not to bump that ball valve open while it's disconnected unless I want a quick burst of air.

[@ididthisforthecomments.5893]

This channel earns its name for sure.

[@dondonaldson1684]

You should consider a ball valve right where your auxiliary tank's hose connects to the main tank so that you don't inadvertently unplug the hose, creating a dangerous volume of pressurized air.

[@timberwolf0122]

I was going to make the same comment

[@diydaveman]

Wow, thank you for pointing this out! I hadn't thought of this but there could be a possibility of someone disconnecting the auxiliary hose and causing it to become a flailing wip and might also cause the tank to become a missile.

Very good point. Disconnecting the auxiliary tank from the main tank while pressurized could be very dangerous.

How would having a ball valve help this situation? Even with a ball valve you can accidentally/inadvertently unplug a hose with the valve open. A ball valve just gives the option of disconnecting the aux tank.

[@johnkeyman1]

I have one comment/question with regard to the connection between the 2 tanks. In this application I fail to see that making that hole "bigger" will produce any noticeable difference as to sped function. Even in industrial applications until your talking a huge difference in volume their is still only slight improvement . Home use not so much I guess it's a good practice..... So my question part is have you ever for home use seen it done without this connection being any noticeable improvement? thanks great video really good job!!

[@ortiz381973]

Thnks for the idea. Is that the same process for a 30 gallon compressor and a 26 gallon air tank. So I don't need a safety valve on the auxiliary tank ?

[@karljay7473]

This helps once the system is up to pressure, but not during constant use. I did the same thing with a 22 gallon system, I added a 20 gallon tank to it and it's better for non-constant jobs, but doesn't make a difference for constant use jobs. I'm ending up running two compressors into one tank and having check valves on each compressor. For most, this upgrade isn't going to make a real difference except when you wait to fill both tanks. A person really should look at the power of the compressor before they buy it, but two compressors into one tank is a good option.

[@brianzielinski2495]

I did this years ago with my old compressor (20 gallon). I added a 12 gallon tank for long runs with the impact or when I use the blast cabinet.

[@750iV12]

What CFM did you need to run the Cabinet?

[@brianzielinski2495]

I don't know. I just bought a simple sandblaster from Menard's and started working with it. My compressor is a Montgomery Ward's model from the 70's and I have no idea how many cfm it produces.

[@CLLeigh]

Time is time. How much more time did it take to fill the auxiliary tank before starting? Was it less time than waiting for the compressor to recharge in order to continue? Just a thought.

[@policedog4030]

Well done and thanks for the demo. I'd try this but that T looks vulnerable the way it is loaded in shear. With my luck the tank would tip over and that T would crack off and bust me in the chops Maybe a long zip tie to provide at least some strain relief and control how far the hose (with the T fragment still attached) could fly? I did check the pressure rating for similar fittings and was surprised to see it at 1200 PSI? Sounds like an awful lot - there are forged brass and cast brass ones so don't know which one that is. I have heard from the grapevine that since California outlawed lead content in brass plumbing fittings guys are finding the new lead-free ones are much more brittle.

[@kracin]

you can also use this method to run large capacity tools like a 3/4 impact and get full power out of it, have a second tank that is 20-40 gallon, inlet size doesn't matter (make it same as compressor tank outlet), once filled, you can run a 1/2" air line out of a 1/2" or larger outlet on the tank itself and get that massive flow you need to run a large tool without buying a giant compressor that will cost 2k+ itself to get that high cfm. the only catch is that your small compressor will be working to fill the larger up, but this should only be for when you need that super high power for a few fasteners like crankbolts and such. the difference between 1/4" line and 1/2" line on a large impact is night and day.

also a good option for spray painting or finishing with a HVLP spray gun

Excellent job on demonstrating and teaching this subject.

[@p2g1949]

Really great video. Good instructions. I've been think about this ever since I picked up an air tank. Where did you get the air lead hose? All I've been able to find have 3/8 inch fittings on both ends or am I missing something in my amateur ignorance. Thanks for your time and effort making this video.

[@eddieallen8982]

need to add a ball valve or check valve to the aux tank so it be removed to for use away from the the compressor.

[@JustCallMeChad]

just add a quick release, no valve needed

[@dfw_motorrad1329]

A valve will be needed on one of the tanks with a quick-release fitting. The quick-release will only seal on the female side and air will drain from the male side. Add a ball valve on the male side and close it when removing the auxiliary tank to prevent drainage of the main tank.

[@lmalino695]

No, ball valve not needed. Think about it .

[@Dan-TheOracle]

a quick release would work just fine but your connector hose will be male ends on both ends. you just have to make sure you unclip both ends of the double male hose at the same time. i have done exactly this on a pressure sprayer i modified to pump oils from under cars and it works just fine, ball valve is probably a better solution tho.

[@spacemanrick2014]

If you add a ballvalve, or check valve, right after the inlet, you must also add in a saftey blow-off poppit. I would have added one on this anyway, as close to the 1/2" port as possible.

[@HiFiInsider]

wouldn’t this over work the motor? filling a larger size tank(s) the compressor was designed force

[@skywu5839]

adjust cut in and cut off pressure at the on of switch, also change the safety valve to the higher one, it can more efficiency without need a auxiliary tank, keep the tank pressure and compressor kick on around 100 psi

[@bobgreene2892]

Excellent, clearly presented tutorial. We especially like your clear narrator's voice, exceptional audio level and good camera angle on all the shots. Your end-summary was helpful, especially the point about when to consider buying a bigger compressor vs. expanding the tank capacity of a smaller system. Please comment-- if the compressor doesn't have to work too hard, does it make sense to retrofit a smaller compressor to a 35-gallon tank, or even larger (for painting)?

[@RealToolReviews]

Thanks! And personally I wouldn’t suggest it. The expansion tank idea is more so for temporary needs vs continual use. If you need more air supply on a regular basis, I’d simply buy a bigger compressor.

[@larryohara6513]

So the only real constraint is the original valve that came with the aux tank. Change it out with a 1/2"NPT w/ 1/4"NPT female and you can hook it directly into the main compressor and skip the tee connector? Does that sound right?

[@tkskagen]

And "don't forget" to Drain your "PETCOCK VALVE" to drain the MOISTURE ACCLIMATION out! Is there a Automatic Petcock Valve Drain available?

[@clwinner1]

The issue is your husky tank will now be running much longer having to fill up new small tank and the regular tank. When your using air tools like impact gun or cutting tool which uses a lot of air the compressor motor will be kicking on all the time or when it does kick on it's going to run twice as much. So how is that helping other than ability to maintain pressure for a little longer or until electric motor burns out. I am just asking because I truly do not know and am curious. Thanks

[@chadmiddleton829]

Cool video thanks for sharing. The parts that you put on can they be purchased at harbor freight?

[@RealToolReviews]

I’m sure most of them can. I think I bought everything at Lowe’s.

[@levipankey]

Any ideas where I could find a cheap used extra tank? Great video. Thanks

[@Shubsru]

Great video. I am now subs. Was struggling for more CFM to use my sandblaster effectively. Lots of Mon. morn QBs in the comments which can be used to my benefit if I choose. Thanks QBs.

[@U812GREEN]

Great hack, but you need to watch the max pressure on your addon tank or make sure you have a pop off valve for over pressure

[@peviens]

I know it's an old video, but why not remove the safety valve on the compressor side, put a Tee fitting, reinstall the safety valve on the Tee and plumb a line to your aux tank? This way the safety valve on the compressor side will work for both tanks and you just use your tools from the compressor side that is regulated. Isn't this the proper way of doing it?

[@Martinroadsguy]

I have a 6 gallon 175psi compressor and my impact wrench works fine with it. The compressor kicks on by the time I'm at about to finish taking the second wheel off, but I can get all 4 wheels off of my car without stopping. With my air ratchet it kicks on constantly and I don't use it much because it's annoying.

[@georgesg10]

How do you drain the water in the tanks , instructions in my compressor book says to tilt the compressor to empty the air help remove the the water (about an 1/8 of a tea spoon ) ? Believe me there is water , Where there is water and steel there is RUST

[@61hink]

Why don't they make air tanks with couplers installed that are plug-in ready to use for this purpose, instead of having to modify something that was made to fill tires? Or do they? Or if they don't, maybe it's not considered a worthwhile thing to do? Just asking.

[@pirateoutlaw6275]

I have a 15 gal. compressor that i added a 7 gal. tank to it so in total i get 22 gal. of air now. I added a T fitting at the drain so the air is equal in both tanks, and a bleeder coming out with a shut off valve for easy draining of water build up. The added tank is made out of aluminum that is rated max psi 200 recommended safe at psi 160 so it works great as my main compressor shuts off at psi 155. I have the air line from the main drain T fitting going to the smaller aux tank, and most of the water goes into it. When i need air that is out of reach of my 50' foot main air line i installed a shut off valve at the air inlet to the aux tank. This makes it so you keep the psi 155 at 7 gal. to take it across the yard or across town, and so on where ever you need air when needed. Also when the water builds up in the aux it is very light to hold up, and open the shut off to drain it. I would guess it spits out about a cup of coffee worth of water. I still drain the main but a lot less now after i added the aux tank about 1/3 rd of what the aux spits out. I have added a safety valve on the aux tank as well, and i always like to check them from time to time to make sure they don't clog up & so on. Thanks for the vid........ , , ⎝⧹╲⎝⧹ÐΛЯΞ †o ÐЯΞΛM⧸⎠╱⧸⎠ ✨[̲̅$̲̅(̲☠)̲̅$̲̅]✨¹°°

[@phillygstyle]

I have a question. I did the same set up. Is the quick connect coupler suppose to leak air? Or do I need to connect a ball valve? My tanks are emptying because I don't always have a hose connected to the quick connect on the auxiliary tank. Thank you

[@kodyamos]

Wasn't sure where to post this so I just came to your most recent videos. Your approach and format lead me to trust what you have to say! So, do you have an opinion on floor jacks? I'm considering and Arcan low profile... Looking for 2.5-3.5 ton, low profile, dependable / reliable, at a good price....

[@RealToolReviews]

+Kody Amos Thanks! What is your price range? Also, what is the minimum clearance you need? Most of them that are 2.5 ton & up cannot fit under very low profile vehicles. I have two ---- and Arcan & Sunex.....the Arcan has lasted for years without issues (other than me shearing a zerk fitting off). The Sunex is much lower profile, but is a 2 ton max.....I use it primarily. Here is the Sunex --- amzn.to/26vL7YD The Arcan was a Costo-special (steel version) & I dont think it is sold any longer. I dont have experience with current Arcan models --- they could be as good, worse, or better than mine.

[@kodyamos]

I'm thinking now about getting the aluminum/steel 3 ton lift from Costco - it's an Arcan which is a brand with good reviews on amazon and it runs $100. Seems like a good deal for a couple of times a year usage.

[@themachinist6554]

For safety shall be always installed pressure relieve valve in each tanks. Also the additional tank shall be equiped with drain valve in the lowest point, otherwise corrosion will appeare because compress air alwyas collect condensate inside tank.

[@RealToolReviews]

+The Machinist The main compressor has a pressure release valve......the auxiliary tank cannot hold pressure when disconnected, and when connected cannot achieve greater pressures than the main tank. Secondly, while a drain valve "would" be ideal.....this is a DIY expansion tank....not a replacement for a larger compressor --- meaning occasional use. If someone was concerned about moisture collecting, they could easily turn it upside down and drain it out the plug/hose. No one should have such a setup as a permanent solution, only to expand the uses of an otherwise ineffective compressor.

[@apatel7787]

Speeding through was the most useful part. Bad choice of timing. Good video for info.

[@phillipabma8093]

agree with Eddieallen add a check valve to the hose end of the T. Also the tank pressure should not be 125, it should be your hose pressure of 100 as it is connected after the regulator.

[@joeydelrio]

anyone know how much (roughly) cfm this adds? i got a 20g tank that makes 5.2 cfm, i need (i think) 7.5 to run my sander and die grinder

[@wcsd9577]

Help me see if I'm understanding this correctly. Wouldn't this setup perform better if the secondary tank was the same PSI as the husky's tanks (125 PSI) rather than the regulated pressure (~90 PSI)? If so how would that setup look? I'm thinking you could remove the drain valve off the Husky and replace it with a brass tee with a drain valve on one side and a coupler on the other, where you plug the secondary tank into so now all the tanks are 125 PSI. Then you run your air tool out of the regulated pressure on the Husky. Does that make sense?

[@blazeaglory]

Could this be done with say, one 3 gallon compressor and another 3 gallon, or the tank from, an older 3 gallon where the motor stopped working? Thanks

[@Canton-ov5vo]

I have a 200 psi compressor and a portable tank with max of 125 psi if I use this method could I set the regulator for 100-125 psi could I safely benefit from the extra reserve tank? Main concern is being safety.

[@stevekennon1786]

Great Video! I recently bought a Husky 4 gal. air compress. Tank pressure is 225 psi. I want to upgrade to a 9 gallon capacity following the guidelines of this video. My auxiliary is the same as in the video....a Job Smart 5 gallon. The maximum psi on the auxiliary tank is 125. Is there any danger of the 5 gallon tank exploding because my main compressor tank pressure is 225 psi ? I'm not familiar with air compressors so any advise will be appreciated.

[@RealToolReviews]

+Steve Kennon your tank will have a metal plate with the max psi listed on it.

[@stevekennon1786]

OK thanks.

[@quinones355]

I also wonder this i have 175 psi and was wondering to add a 12 gallong to my 4.5 gallon husky but the pai difference worries me

[@TheGadgetAddict]

Wouldn’t the add on tank be less pressurized since it comes after the regulator on the compressor? Yes you are adding more air volume storage, but it is limited in the third tank no?

[@roadrageburleson]

Thanks for the video. I now have a weekend project to do. I have one question though, what was that impact wrench you were using to take the wheel off, I really like that compact size.

[@guillermokrimpenfort]

[@RayRosher]

Excellent Video. But bear in mind that the electric motors and compressor have a limited run time. Usually 15 minutes max! then they must be rested for a time..

[@sunshinetv2419]

Thanks... great video... I was thinking about doing this but wasn't sure of the results... thanks for putting this video together

[@spinb]

Great presentation. I'm going to do this. My only question is: how do I drain water from the storage tank without a drain at the bottom and the removal of the drain valve at the top?

[@paulmo4076]

Turn the aux tank upside down with a little air left
