Come along as I go into a residential Plumbing DWV (Drainage, Waste, Vent) and Supply Pressure Test.#inspection #residential #plumbing #drainagepipes #water
Thanks! I am ripping through all your videos. Reading the codes is one thing. Seeing it in the field is another. Very helpful when you not only point out the specific violation but where it applies elsewhere like you typically do. How about a video on plumbing cleanouts and where they are required?
I've never had the pleasure of shadowing a plumbing inspector so this is very informative. One question, just how far down the line is the ball placed in the drain line? And is there any test for the line beyond that, say, out to the street?
It really depends on the layout. There's an underslab plumbing inspection if the house is on a slab, which is what you saw in the video. There's also a sewer lateral inspection. (Sewer connection to the street). To answer your question, a test plug is installed where the new drainage meets the existing.
So if you have no water service to the building because you are waiting for the water department (construction held up) or it is winter..... cold temps. I would have concerns of testing with water you would never get all the water out of the lines unless you blew it out... . liner test yup great go ahead and sheetrock then during construction liner gets damage. I believe that all shower pans should be a copper pan with the brass drain soldered in.
The irc/Ipc has a major contradiction when it comes to the plastic testing. Both say you cannot use air on plastic but 312.7 forces sewer test of the IPC requires 5 lbs of pressure greater than then working pressure of the pump. So the only way to do that is to air test it. Cannot use working water pressure that will creates a cross contamination situation..
So, first of all, the plumbing section in the IRC is straight out of the IPC. Personally, I don't like air for any type of plumbing pressure test. It's easier to locate leaks with water
@@PPG1967 How do you stack fill an 1 1/2" lift station pressure line 5lbs higher than the working pressure of a 25 lb pressure pump? Thats where that contradiction come into play.
You're always informative. Thanks for the video
I appreciate your support, and thanks for watching!!

I'm about to get my inspection for a remodel thank you , very informative
Quick question , how do you make it so that the water doesn't overflow through the showers since they're are below flood lever rim ?
Plug or cap that shower drain.
Good video, thanks for the information.
I appreciate your feedback, and thanks for watching!!
Here in Michigan, you cannot have 3” elbows horizontal to horizontal.
What code book??

Normally, in the wintertime, we allow air.

The sewer drainage test required pressure can be achieved with a stack filled drainage system.

Ok, I misunderstood. You can use water or air with a forced sewer test.

Dirty arms are to long to the tee
Huh???...for the size pipe (1-1/4") the maximum is 5'
