How To Pressure Test Plumbing And Hydrostatic Test Plumbing! (for plumbing inspection)

In this video I will show you how to pressure test plumbing. I also show you how to do a hydrostatic pressure test on plumbing before a plumbing inspection. The pressure test with air is for water supply lines that are PEX pipe. The hydrostatic test is for the drain lines in the house.

One of the best demonstrations. To the point. No drama. Like your humour..

[@bobtribe]

Straight to the point and clear, thank you for this! I saw too many videos where people just jump right in already with all the components, makes me say; "Hey, if I'm looking up a pressure test video on youtube I don't have the components to test..."

[@alvinlowe843]

Very informative. Also, including your bloopers for all to see as well may indicate at least a few things about you, and about putting together good videos in general. Showing your bloopers tells me you're persistant, pretty comfortable with yourself and who you are, and you are serious about and diligently work at whatever you do. And in general, putting together good videos like this one requires a lot more preparation, time, and patience to produce than is otherwise apparent. So thanks a lot for taking the time to do them and for saving viewers like me lots of time and money (saved).

[@kyscott4561]

I had to do a hydrostatic pressure test on the drains, in an addition that my mother had built on her house. The inspector wouldn't let anything short of a full fill pass. So it took me a good while sitting on the roof holding the water hose. Lol it passed but your talking about fun when I let the bottom plug loose.

Great tandem video to your pex install, thanks!

[@TheExcellentLaborer]

I appreciate that! Thanks for watching, and take care!

Love the outtakes. Production takes work. Shout out to all those who don't mind putting in the work like Josh.

[@TheExcellentLaborer]

Glad you like them!

[@wsnider28]

This helped so much. Thanks for the quality videos-enough detail to cover everything, but no fluff to scroll past. Nice to have that confidence in the system before the walls are buttoned up!

[@BathroomRemodelingTeacher]

Another great tutorial! No doubt experience shows. Can always tell by the presentation if someone is demonstrating for the first time or has done it many many times. Great job 👏

[@TheExcellentLaborer]

Thanks a lot! Yes I have done at a time or two 😉. I appreciate your comment. Good luck on your bathroom remodeling!

[@77Avadon77]

[@majid_us]

Is it okay to use the inline valves (e.g., under kitchen sink) instead ( in place) of capping the ends of the hoses when pressure testing? The valves of course would be in closed positions.

I just re-watched it to see what you were talking about. I had to laugh watching it again lol. Every once in a while I’ll have some pretty funny out takes and I will add them to the end of my videos. Thanks a lot for watching till the end that is so awesome!

[@MatteoMazzulloRevel]

@@TheExcellentLaborer usually people watch those videos out of necessity like I find myself now. They tend to be a boring topic if this isn’t someone’s main profession, so it was refreshing to see someone that doesn’t take himself so seriously and definitely put a smile on my face during this frustrating inspection process for my home. Should be your signature on all videos. Good work!

😎 bloopers. Learning allot thanks

[@TheExcellentLaborer]

Thanks for watching Tim!

[@plumbbuild6517]

Nice job dude , the drain lines is alittle problem sometimes, I was having problems on my drain lines leaking sometimes but I started deburring all my lines having had near as mush of a problem with them. I had a leaking water on a pressure test and found the Shark.bite on a similar set up as you have for your test leaking so it good to change them out after several test ,I guess the rubber seal cracked. Thanks for sharing this video hope all is well.

[@TheExcellentLaborer]

Drain lines are always more of a pain than the pressure lines I have learned too. I have never had a rubber seal cracked. I bet that was an interesting find! I am glad you are liking my videos. Stay tuned!

I am 100% confident that I will be building my own house after watching your playlsits... u r the MAN! The bloopers at the end were priceless :). I hate smiling... so that, along with not knowing anything, keeps me from making videos 🤣. I know it varies but a 20-minute video has to have 4 to 6 hours +/- into it with the re-takes and editing... right?

[@bybryanwhite]

I appreciate you bro bro!

You are welcome!

[@Bschintz_67]

love your videos. And the Bloopers at the end made me laugh...thanks

[@Andy-gw7hd]

If you water heater is hooked up wouldn’t it connect the hot and cold already

[@BOSS_805]

Love the video, but when pressure testing the water lines doesn't the hot water tank interfere? Also is there a way to pressure test the drain lines with a pneumatic adapter of short?

[@arun4846]

Thanks ❤️❤️❤️

[@TheExcellentLaborer]

No problem!

[@marc714714714]

Great videos and you are awesome.

[@camborwade6546]

What is the next step to depressurize the lines/gauge?

[@rodneyarnold5970]

Hello Josh, Thanks for doing your videos. I have learned tons. I do have a question. In your pressure test video I noticed you have a stacked double drain pipe connection at your kitchen sink location. Why did you make up that configuration?

[@TheExcellentLaborer]

Hey Rodney! I’m going you install a Studor Air Admittance Valve on the top portion of that setup. I did that because I would had to drill through the jacks of the window and it would have weakened the framing. So with this set up I can just put a ventless valve to do the trick. Hope that helps!

[@akclary999]

New homeowner, So I'm can this be done on my house after it's already built and I am losing about a gal an hour with nothing on? Or should I get different test done?

[@DesignbuildsolutionsLLC]

How long does it take to pressurize your system?

[@user-lf7en6rf8m]

Thanks josh lmao. Beep beep beep. Your videos kick ass ,

[@TheExcellentLaborer]

Thank you P! I’m glad you are enjoying my channel. Stay tuned for more 💪🏻🔨!

Got 100 psi in my sweated copper currently. This house is my house I'm building and I've never sweated copper before so wish me luck

[@jasondeleon5511]

When you slipped on the pressure test adapters to the PEX. Did you have to crimp the fitting to PEX, then cut off later.

[@jasondeleon5511]

Ohh it’s that shark bite fitting. I caught that. Just needa get that plastic removal tool👍🏽. Thank you again, for you videos.

[@WallerAve]

Can you still do this if you have a tankless water heater installed already without it damaging the electric tankless water heater?

[@watavuemountain481]

Thanx for the how to…. We are done with our install, pressurized to 60 last night, at 10 today. Did the soapy water on the fittings, NO bubbles anywhere.!! Any recommendations?

[@winterfar2814]

How much did the temp change? This is late but may help someone else.

[@watavuemountain481]

@@winterfar2814 I think about 20 degrees and it’s all still exposed. We didn’t even think about that having an effect.

[@charlesbutterfield995]

For some reason I cannot see any link to the valve stem and pressure gauge. I DO see a link to your Amazon store but cannot find either item there.

[@johntherat339]

Would this method work if there might be some water still in the line? I am trying to make sure I have no leaks before I install my wall panels.

[@TheExcellentLaborer]

Yes it will work if some water is in the line. Good luck!

[@barrym266]

Re the drain pipe testing: What about the tub overflow? Why doesn’t the water pressure push water out?

[@pelidomi1975]

Do you have a vide how to install a water heater

[@TheExcellentLaborer]

Not yet. In about a month I will. Stay tuned!

[@pelidomi1975]

@@TheExcellentLaborer thank you

[@Packer9037]

If you run every line back to a manifold would you still need to pressure test? I’m assuming no since every line runs right to the fixture, but can’t find the answer online.

[@lillithjones993]

Hey Josh thank you for your informative video! I have a partial remodel and I have installed Pex A and I have already installed the shower diverters. Will I still be able to do a proper air pressure test with having all the valves closed? The water heater lines are capped I decided not to connect them to the water heater and just pressure test the hot and cold lines separately since I’m not sure what I’m supposed to do to the water heater during a test

[@oldoldpilgrim7898]

I couldn't find the valve stem in your Amazon store. Where should I look?

[@TheFlyingZulu]

Under 312.5 water supply system test in the IPC codes states you can only use air pressure on pipes other than plastic ones... So this is not a correct way to pressure test your plastic PEX lines... How do you past inspections doing this? Does your area use different codes?

[@Faruk651]

Yes dummy every area has different riles. Get out of that bubble.

[@user-od3wm1rl5w]

Do you leave the hot water tank connected?

[@levileach1786]

Can I pressure test with a cartridge already installed in my shower valve or do I need to get a cap for it

[@missyrabbit5250]

the temps dropped below 20' and my pvc blew off the booster pump. I noticed there is water in the gauge. Should I be concerned?

[@joycebuchanan1349]

How or what is used to cap off the toilet?

[@mattarenz1195]

Hey Josh, what is that piece on your drain testing rig that has threads for both the inlet and gauge, I cant find that part anywhere. I dont see it in your amazon store either

[@brunoumoffia6098]

We have the same tattoo on the same arm 😅

[@Trifiveguy]

I just tested my water lines with pressure and I c at find the leak it won’t give me a chance to find it it bleeds out that fast working on my own !

[@stripedaddydiggs8780]

I’m Not a professional, but don’t you use water instead of air, or is it dependent on your local code

[@ChrisUhlik]

Suggestion: I'd like to see a video of how to safely release a 3" test ball after a drain test. I've got a remodel where I need to test the new drain upstream of a 3" wye. I've got a 3" test tee in the new line and I can get a test ball into that tee, but it's going to have 2 stories of pressure behind it and more than 30 gallons of water. I'm imagining that when I release the test ball pressure, it's all going to come blasting out of that tee in my face and all over the crawlspace. How do you guys handle that?

[@stevenbruce2362]

You can get a transfer pump and a long hose and pull the water directly out of the pipe using the pump. Put the other end of the hose in a spot where water can flow like the grass or something. I see this is a year ago, but thought I’d answer it just for others

[@Christianwarrior2014]

Hey man! Awesome video! I was hoping you can help me answer a question for plumbing rough in? For the shower rough in lines, do I attach them together for test? Thanks man!

[@TheExcellentLaborer]

I usually install the shower valve and then plug the drop ear for the pressure test. If not I would just plug the hot and cold separate. I hope that helps!

[@Christianwarrior2014]

[@Christianwarrior2014]

@@TheExcellentLaborer Hi! Good morning! I had one more question for the rough in plumbing for my small shed home. Do I need to connect the main water water line from my water pump or can I just cap off the main line? Thanks man!

[@danrichards496]

Ugh. Ran Pex under the house, making sure to get my cinch clamps on right. Aired it up to 100 lbs and 36 hrs later it lost 30 or 40 lbs. didn’t hear any hissing when I done it. I guess I’ll spend my next days off trying to figure out what’s wrong. So disappointed.

[@blondestrainger]

As a Master Plumber we never use air on tests especially PLASTIC ! The potential energy in air will send parts flying !!! Hydrostatic test everything but you can always fill with water and use an aircompressor to build to 150

[@ModernMessiah]

To test plumbing on tiny homes you use this method by code
