Pressure Testing Our Drain-Waste-Vent Pipes

If you do a pressure test and don't find any leaks, did you really do a pressure test??

Isn't tape and pipe dope overkill? Shouldn't pipe dope be sufficient?

[@shawnfahey7243]

I totally liked watching your review on the DWV testing.

[@ChristopherBurger-m2s]

A positive air pressure test is not allowed in the state of Connecticut. The only two acceptable options is a vacuum test or a water test. Some manufacturers may actually require you to replace all of your DWV pipes if you put an air test on the system. Please make sure to give your local jurisdiction a call.

[@MasonDixonAcres]

Our area is either 5psi air or hydrostatic water, most jobs I've seen by plumbers in both residential and commercial settings use air

[@michaelvrbanac6923]

You don't need both tape and dope. They act only as a lubricant.

[@jackiehowes9092]

I love following your progress and enjoy how thorough you are. Can wait to see what the future holds for you youngsters ❤

[@BOSS_805]

Using air to pressure test PVC is a bad idea, positive air pressure is combustible and PVC drain lines are not ready for pressure which could in turn lead to an exploding sort of pipe bomb. Never exceed 5 PSI. Your best bet is to use negative air pressure AKA suction and watch your gauge to test for leaks. Next time just use it 4-in plug instead of that insert bladder thing

[@JTTTTx]

Please remind your viewers that not all plumbing codes are the same. There are some jurisdictions that would fail you for the Fernco inside a building, air admittance valves anywhere on the installation and most importantly the wrong gauge used for the test-- must be a lower range attached to the system.

amazing....you are the best

[@lukekaz9]

I get the adapter with threads and screw it into a clean out so I don’t need to glue it on

[@MasonDixonAcres]

Very good idea - will steal that for the next build

[@bgd5339]

If you only had one small leak, I would call that a success. 👍

[@johnf8877]

I just got finished watching your AC video, have you considered the amount of room needed to install your stone between the AC unit and the wall. I am putting this here hoping that you see it instead of a month old video. It is hard to see with the camera angle in that video.

[@MasonDixonAcres]

Yep it should be okay, a little tight but about 30” I believe

[@robertbuck7186]

good job...

[@envoyabroad104]

Thank you!!!

[@DarrylHamilton-dm1de]

Hey buddy where'd you find the yellow extension?

[@MasonDixonAcres]

Supplyhouse.com as per usual

[@VINODPVARGHESE]

Good video

[@jamesc1283]

I was curious so did a bit of googling and found this: "Fernco (Rubber) fittings are not approved in wall framing unless they have a metal sheathed hose clamp assembly covering the entire fitting as part of the design, Which limit them to straight couplings or reducing couplings. The reason is that vermin can chew through the rubber. They are suitable for underground but are more expensive than standard no hub couplings or regular pvc fittings. So the reason for wanting to use them for that is questionable unless there is some sort of access issue." So I doubt having that coupling in the wall would not be acceptable to your inspector. It sounds like the full-metal covered couplings are ok, and honestly based on the way that was bulging I'd think you'd want that anyway. I'm curious if your inspector already passed it though.

[@jamesc1283]

And to not just be negative in comments, I've watched a few of your videos and I'm enjoying them so far!

[@MasonDixonAcres]

Thanks for the research! Is that in the IRC or where did you find that? I really can’t imagine a mouse chewing through that boot and not also chewing pvc wire insulation, PEX, etc. so I’m not too worried. The inspector did already pass it 😄 There’s no inlets above it so it should never ever be under that kind of pressure again (if the drain stops up, it will come out the utility room floor drain).

[@stevestadterman9270]

believe or not,,mice/rats find the rubber more tasty,,@@MasonDixonAcres

[@JohnFarrell-jo2sw]

Don’t know why he didn’t just redo the thing right and glue on anew couple of fittings and be done with it forever and not have to worry about it coming back to haunt him later on but hey that’s on him
