I amended that required test out a long time ago when I saw a yahoo release a fernco cap under pressure and it about took his eyeball. I felt so bad I told the GC "that's it, not doing that anymore!"

The water test in a 10ft head pipe just about as asinine as testing with air, got to drag a stepladder up three flights of stairs, then go get the garden house, then the plumber's caps leak. Then they forget to cap the tub or don't glue the shower drain, what a waste of a day. Ooh, they changed the code lowering the pipe, thanks bunches!

In my neck of the woods which is endless summer, it is strictly water test with head pressure. In PA I saw a lot of air pressure but at low pressures.

Bit of information, if you research cast iron, copper, glass and other plumbing pipe manufacturers and standards you will discover they will tell you not to test with air alone. Some will allow a hydrostatic test.

Another bit of information; most of the caps used for testing are only listed for 4 psi, so doing a test with greater than 10 ft of head exceeds the listing of the caps.

Do you enforce any codes you don't agree with?

The purple glue requirement got a little testy, the plumb guys wanted to use blue glue, and the brand I did research on claimed that it did not need primer.

It's rough out here, a lot of itchin, bitchin and trickin goin on!

You do know that the 2000 IPC allowed air or water for plastic, right?
