Thread: Pressure test

  1. #1

    Default Pressure test

    Well the remodel is going along fine, and I have installed most of the plumbing, my inspector came over today and told me that I would have to preform a 10ft water test on the system. I understand that I have to fill the entire drain and vent system with water and wait to see if there are any leaks for 20 minutes. He told me about an adapter that is available that allows you to hook the water up at any location rather then filling the system from the top of the roof. I haven't seen anything like that...does any one know of an adapter like this or am I stuck filling it from the roof! Any links or other information would be great!

    Thanks

    When I test with water I usually glue an 1 1/2 pvc female adapter onto the lav drain. Then install 1 1/2 x 1/2 blk or galvy bushing into the fem adapter and then srew in a 1/2 boiler drain or draw off same thing. Hook up garden hose and you're good to go! Of course don't forget to plug the other drains !

    I screw a 2" x 3/4" bushing into a cleanout tee, you do have cleanout openings I hope, with a hose faucet into it.

    HJ you’re a genius! I never thought to use the cleanout with a bushing...done deal! Now if only I could find a reasonable price on a long 3" inflatable plug to put in a 3" wye connection!

    Default test plug

    No such animal, but at least you can reuse them.

    Anyone have a good solution for what to put at the end of the pipe that I need to test? Right now I have 3" ABS connecting to the old 4" cast...the inspector told me that I needed to do the water test all the way to this location. He suggested to put a wye connection at the end near the 4" cast and buy or "find" a long 3" ballon that would fit into this wye. I have done some research and have found a manufacturer that supplies such a beast It's made by Cherne but I can't seem to find a local dealer...besides, if I did I am sure it's not cheap. Does anyone have any other solutions? I'm open to just about anything! Thanks again in advance.

    instead of a y install a 3" test tee. then install a 3" threaded test plug. cherne calls them a clean seal plug. follow instructions! test ball can kill! make sure you have secure plugs on all terminations.

    Question I'm curious about water tests too...

    Okay, so I fear I'm gonna have to do the same thing, so I have some questions about this also. Since the experts are already here...

    I am moving a sink, and so rebuilding a 1-1/4" copper DWV drain line and revent with 1-1/2" ABS (this has its own complications...).

    This is in a bathroom right near the main 3" copper stack, and so the lav drain is the second highest tee into the stack (back to back toilets are highest). The revent ties in at 42", so 10ft is basically to the roof.

    If I put a test plug at the cleanout and fill to 10ft above the revent, that would fill ALL of the 3-4 drain lines tying into the stack. But these lines have sinks, tubs, showers, etc. on them. So how does one typically plug these things off when performing a water test???
