Hi Zim, My my water city valve located up of the valve that you turn off in the video. If I turn it off the valve, then the city water is not going to the system as picture. Should I turn off the valve or not? Thanks

[@fixitwithzim]

@@nhatlinhvo no, don’t ever turn off the water feed to the system. That always needs to stay on! Many residential systems don’t have a low water cutoff. You can create a dangerous situation with the makeup water turned off

Hands down the best explanation of “how to” video. I am super impressed by you taking the time to explain everything including the expansion tank. I am still new to hydronic boilers so this is a blessing to see first hand.

[@fixitwithzim]

Thanks, glad the video helped you!

[@jaybee1930]

Yes thank you for this very well explained purging process

[@bnice12]

This is a great purging video for sure...only discrepancy I have is regarding inlet of expansion tank. The orientation of the label means nothing. How the info is printed on the tank is only that way because of manufacturer. The correct way to tie in an expansion tank on horizontal piping is not hanging below directly it, particularly in a system with iron components. Eventually particulate matter from these components, or copper shavings, etc will settle in that port and on top of the diaphragm causing he tank to fail. Upright is best, if the tanks Schrader valve is not too high and accessible. Many if not all horizontally plumbed air eliminators have a 1/2" port on the bottom for expansion tank hookup and this is fine as long as it's offset with a few elbows. Expansion tanks lose about 1# of air per year thru osmosis...so they need to be checked yearly included in the annual inspection. They should be plumbed in as near to the boiler as possible and as near to the Autofill/prv as possible. This is your point of no pressure change and if possible...ALWAYS pump away from this. You will have virtually zero air issues if it's done this way. Expansion tanks should be plumbed in to the system with a valve and then boiler drain before they tie in because the pressure must be drained off the tank before checking with gauge. Hope this helps!!!

[@dubmob151]

​@@bnice12 that all makes sense, that the inlet should be on the bottom and the air bladder above. If the expansion tank has no air pressure in it and then filled with water to the nominal 12 or so psi, would that damage the bladder in the tank or does it have enough flexibility to push all the way to the walls of the tank?

Hi! My aunts home as inherited, was built in 1942. I went from Florida to Maryland for Thanksgiving. There was only heat in the living room and dining room. Needless to say, my Florida butt was freezing in the house. (30 degrees inside) So all back story aside, I wanted to thank you. My son and I watched your video, and then went into the basement and fixed the baseboard heating for the whole house! Thanks so very much for sharing this information.

[@jdoyle4811]

I have been cleaning, maintaining, and repairing my Buderus/Riello burner with indirect 40 gallon water tank since installed in my house 15 years ago. I empty the horizontal hot water tank which sits directly below the boiler every two years to vaccum out salts and sand that fall out of the water. I was surprised how much the sacrificial rod had eroded in two years after replacement. The fill valve information was super important as I had problem of air entering into the system automatically under normal 12 psi because of too much air in the system. I had not left the faucet open on second floor so too much psi in system. When I open the metal tab on fill valve all the way to allow water at city pressure I good to go from there. Best hydronic instructions for hot water boiler on KZbin bar none, Zim.

[@edwardyoung5644]

This is a great instructional video for many with baseboard heating systems that need to be purged to get the air out. Great job. There is one of your statements that I disagree with… and I feel that it is very important to make a note of herein.. At about 10 minutes and 25 seconds you state that "you do not want to have a relief valve discharge because once it opens up it will never close again." THIS IS A DANGEROUS STATEMENT to be telling the DIY community. If you read the instructions that come with that particular relief valve, it clearly states that you "MUST OPERATE THE RELIEF VALVE ANNUALLY" to be sure the passageways are not blocked. There are three things that can happen when you operate a relief valve. 1. The valve will not discharge any water at all because it is stuck closed. That is not a safe condition and can cause a boiler explosion. You MUST NOT OPERATE that boiler until there is a working relief valve installed. 2. The valve will open and release water as it should, then the valve will attempt to close and may leak. You can try to clear the debris that is keeping the valve from closing 100% by operating it again and again until it seals completely. If it does not seal completely then you need to replace it. 3. You operate the relief valve and when you release the valve handle the valve closes and the water stops flowing. I find this happens about 75 to 80% of the time when you operate the valves annually. In all three outcomes, you end up with the knowledge that you are operating a safe boiler in your home. NEVER TELL PEOPLE NOT TO FOLLOW THE MANUFACTURER'S INSTRUCTIONS WHEN IT COMES TO RELIEF VALVES.

[@fixitwithzim]

[@sptrsttradr4918]

Thank you! For anyone struggling--read this. Basic premise is you need to know the direction of the water flow. You want city or well water to come into the boiler through the pressure regulator, go through the boiler, and out into ONE zone at a time but before it gets back to the boiler you want to close a valve to stop it from going back into the boiler. Hopefully, right above that valve, you have a drain valve that you can hook a hose up to and let the water circulate until no bubbles come out. I have one circulator and three zone valves. The zone valves are usually on the return side and they have arrows on the brass to show the direction of water flow. To help others, in the Read More down below, I've listed Nine steps that worked for me. Step 1--shut off power to boiler. Step 2--note what the pressure is, there should be a dual gage that shows temperature and pressure. Mine was 18lbs but I think most are lower. Step 3--figure out direction of water flow, usually up out of boiler, past expansion tank and splitting off into multiple zones. Step 4--wherever the zones come back, shut the valves on all but one of them. If there are no physical valves, you can leave the zone valves in the auto position and just put one of them in the manual position, which is open, and you can bleed that zone first. Step 5--close the main return valve to prevent water from going back into the boiler. Step--6 hook up the hose to the drain valve which should be right above the return valve you just closed, and put the hose in a 5 gallon bucket where it can overflow and you can see the air bubbles stop. On my three zones, there was one that took a full five minutes before I saw no air bubbles. Step 7--Close the drain valve, close the physical valve on that zone or put the zone valve back in auto mode and open the valve on another zone. Repeat the whole process. Step 8--Close the drain valve, open the main return valve so that water can get back into the boiler. Use the lever on the pressure regulator to bring the water pressure back to where it was. Step 9--Pat yourself on the back for being a can do person!!!

[@ScaesarBtech]

@sptrsttradr4918 I have just one zone but my drain valve is below my main return valve. If I'm understanding this correctly, the only way I can drain my system would be to have the water run the opposite direction through the system than it normally does. Is this OK?? The city water water coming in through the pressure regulator would go first through my whole house radiator system then come back past the expansion tank, into the boiler, then out the boiler, through the recirculating pump and finally get to my drain valve attached to my hose. Will this mess up my boiler to purge this way?

[@sptrsttradr4918]

@@ScaesarBtech The water can only run in the direction that the circulator is set up to pump it. Without seeing your setup, it's hard for me to give you advice. If it's not clear what you need to do, it's best to hire someone. Sorry to say that, but that's the best advice I can give.

Hello ZIM.... I saw your video on how to stop your furnace from continually running. Remember you replaced a Relay inside your furnace? Remember how that fixed your furnace and it stopped running when the thermostat told it to? I replaced my Relay, like you did, and it did NOT stop the furnace from running. For sure that relay was BAD and needed to be replaced. You were Spot On. But I had to shut the main power off. I've been doing that since winter of 2019. But guess what? I found two metal boxes outside the furnace, mounted on the wall. I finally took the covers off of them and found that each one had a RELAY in them!! So I replaced those on Thursday, November 5th, 2021. Now my Furnace DOES work again!!! So, having replaced that first RELAY inside the furnace and then the other two.. well It does shut off and stay off when it should!! The reason I'm posting this message on THIS video is because I see you have TWO metal Boxes just below your Main Power Switch. Have you looked inside those? Do they each have a Relay in them? Your videos have been VERY HELPFUL!! Thank you so much!!

[@fixitwithzim]

[@TheNYgolfer]

Good info. I wouldn't however recommend turning the fast fill lever to max pressure. Good chance the inexperienced home owner will cause the pressure to rise too high inside the boiler, causing the pressure relief valve to open. Most importantly though the procedure of turning the max fill lever to it's maximum can be very dangerous if you don't know what you are doing, or you forget to return it to it's normal position once done bleeding. Why? There have been cases of pressure relief valves failing to open and boilers exploding due to high internal pressures.

Fantastic Video. It worked perfectly for me following the instructions. The only thing i would add is that for people like me who have “Zone Valves” that open each zone when the thermostat calls for heat, there isnone more step that needs to be done, that is to manually open the zone valve in the zone you are purging the air from so water can flow thru that zone. There is a lever on my zone valves that I move to do this. Then after that zone is purged, I move the lever on my zone valves (Taco) back to the normal (closed) position.

Definitely took the time and effort to think about how people don’t just automatically know about different names for different valves and how the system works and I gotta say you have the best how to video I’ve looked at others and they confuse you more then they help Thank you for your video god bless 🙏💪💪

[@fixitwithzim]

That’s great to hear!! Thank you so much!!

[@KevinMagnani-ot1ux]

Phenomenal Video! Extremely well explained for the novice! Easy to follow!

[@fixitwithzim]

Thank you, appreciate it!!

[@PeiN361]

Best clear tutorial I have seen so far thanks for the vid buddy I have watched about 3 videos before you and they they weren’t thorough. Thanks again for the clear well put explanation

[@fixitwithzim]

I appreciate that! Thank you!!!

[@rshaddock]

This video has the clearest instructions,

[@fixitwithzim]

Thank you!!

This fixed my system and I learned about my fill valve. It saved me some coin and warmed my house a day faster than the service people could get here. Thanks!

[@fixitwithzim]

Great!! Thank you!!

[@tsgrimey]

Thanks for the informative video. I have an exact same heater system with 2 zones. All I could see before this video was a spaghetti of pipes, but now after watching this video, it all makes sense.

[@fixitwithzim]

That’s great!! Thank you!

[@mickm8594]

By far the best video I've seen on the topic, especially with those extra handy tips! I'd also mention that all the new water added also has some air trapped in it and that it's the job of the air vent (which is beside my expansion tank) to slowly bleed that off. After I purged my system it gave off a couple hisses soon afterwards that was reassuring to hear. Also, it's a good idea to permanently keep a 5 gal bucket below both the pressure relief outlet pipe and backflow preventer outlet pipe.

Glad it was helpful! Thanks for the suggestions and feedback!

[@graniteforestdojo1372]

Wow! You, sir, are a superb speaker. I don't think I heard an "uh" or "um" once, and you were just free-thinking while you worked! Oh, yeah-and super helpful, too! My house is 45º right now, but I hadda take the time to write that. Many thanks, and brilliantly done.

[@skiskate4food]

Great explanation, a long winter without the sloshing and whooshing, much appreciated!

[@cindymarino4969]

I cannot tell you how much I love this video! Now we need to figure out how to drain since we do not have a shower only a slop sink.

[@fixitwithzim]

You can run it outside through a window or up the stairs of you have to. It’ll take a little longer but will still work the same 👍🏻

[@niceday8888]

Thank you so much for such detailed, step by step explanation! Got the air out of my heating system. Liked and Subscribed. Also had my husband and son watched this video multiple times, saved and liked. Cannot thank you enough!

[@fixitwithzim]

That’s great to hear and thank you for the sub! 👍🏻😁

[@constantelevation5702]

Thank you so much for this! Others that I’ve seen did not point out the opening of the fill valve and I think that missing piece is why air remained in the system. Once again, I appreciate you bro!

[@fixitwithzim]

You're welcome, glad to help

[@steveraymond6169]

Oh Man! Thank you! We purchased an 1840 home with forced water radiator heating, but always noisy with gurgling water in the pipes. We have three zones in the 2700sf home. My wife thought we should be bleeding the radiators, but this looks more direct and efficient.

[@williamdyckman9704]

I used your video to purge air in lines from oil fired boiler. It worked very well and I want to thank you for saving me $$ !

[@theotherserge]

Your bucket trick is some blue collar genius, I was about to give up on purging my HydroTherm radiant boiler, I could not figure out how much water I needed to run through the system. tyvm!

[@knightofthelivingdrones2646]

I have been maintaining my boiler since 2004. I have not had air issues until this year. This is very through and helpful! I only have 1 zone with bleeder valves and that was added during a remodel. I had no idea how to purge the other zones. Thanks for making the video!

[@fixitwithzim]

No problem and I’m happy to hear you found the video helpful!

[@SparkeyDogfish]

OK, I am totally jealous. I see what you are doing. You are the same type of DYIer as I am. You however videotaped your projects. Real cool. You got me thinking if I made different clips of my projects as well as documented existing things, it would go a long way towards having anyone else understand my systems and such. I have a couple of three ring binders with written documentation of my electrical, plumbing, boilers (gas and coal) and different things I have implemented. Now I need to start taping. Thanks for the inspiration.

[@fixitwithzim]

You’re welcome. I’m not going to lie, filming the work makes the job 10 times longer but I’m the end, it’s all good and gives me a sense of satisfaction. Good luck, It’s a fun process!

[@dicklemieux7441]

I agree with the other posters who are complimentary. This was the 5th video I watched before tackling the job and it clarified everything the others only confused. Thanks for a good job!

[@TheEzmortal]

First guy to clearly explain the procedure.

[@Samlol23_drrich]

You didn’t miss a trick. Well done.

[@fixitwithzim]

Thank you!!
