I'm installing a half-bath (toilet, sink) on my second floor. I'm doing the work myself. Right after the rough-in was finished, the city inspector came in to inspect. At that point, I had to perform an air pressure test on the new lines. (Plug up vents and drains with test balls, which was a major pain since the balls kept slipping out and it was hard to fill them up and etc....). It passed.
After I am done with the rest of the project (i.e. with sink and toilet in place and hooked up), the inspector will come back to have me perform a SECOND test. This second test will also be involve closing up the vents and drains, but will also involve putting a flexible plastic tube down into the trap of the toilet.
Can anyone fill me in on the details of this test? I'm not really confident that I know what I'm supposed to do.
The tube is supposed to be shaped into a U-shape. One end goes down into the toilet. The other end I blow on, to blow air into the system. Then, I supposedly read the level of the water in the tube? Okay, but how do I get the air into the system if I have water in the tube? Do I use two tubes, one to blow air into the system, and one to read the pressure?
What is being tested with this test?
Any help would be much appreciated.
Thanks,
