In response to Re: Pressure test
: : : Does anybody have a good link on how to make a pressure test assembly for a DWV?

: : : Or maybe somebody has some info on what parts I could pick up at say Home Depot.

: : It's easier to do a water test if water is available. If you want to do a 5 pound air test you can connect at your lavatory or sink trap arm with a solvent weld by threaded adapter and then use a bushing to get down to 3/4" threads for your test guage and air inlet valve assembly.
: : DO NOT put over 5 lbs on DWV. When you are done cut off the thread adapter and attach your trap adapter. LonnythePlumber

: Thanks for you info. Our local inspector wants air pressure and not water.

: Also another question is what is best to use an air compressor or try to use an air pump?

: Ernesto
Ernesto; 5 PSI is not that much to pressure up to. I have used an old bike pump, had to pump several hundred pumps but it did it. (unless you got 0ver 100' of pipe.) good luck Hube
