 Plumbing vent inspection testing
Author: yzman720 (MO)

New constreuction home -
Wanting to test my venting with a pressure test before I sheetrock
At my clean out I have already connected my main drain to the neighborhood's sewage system

Is there anyway to test it now that I have already connected the main line? I can't think of a way to plug it its already buried so I am trying to brainstorm

Also I know this is for a leakage test but are there any test you can do to tell you if everything is trapped and vented correctly?

I guess your local codes do not require testing and inspections. You are going to have to cap all the vents and drains first. Then put a ball plug in the cleanout that should be located where the pipe comes through the wall. Then somehow rig up a system to get the air in the lines.

As far as testing the traps and vents, you can do a smoke test or a peppermint test.

First you can test ball with stem extensions to hold the connection point.for any true test all points below the roof will need to be capped or plugged.We have been allowed to test by segmented/first ground rough, second and third floors,so on through. to roof vents.each pipe must hold a five foot head above its full point horizontally. With the exception of the vent terminal which is exempt so far.

This is SO FAR FROM LEGAL, OK U want to test it Plug every place in the house you have a fixture, plug the ILLEGALLY connected main, go up on the roof stick a hose down the vent if you have one, let it run until it runs out on the roof, Shut the water off and let it set for 6 hours,call you local officials and have them take a look at it. if they approve then you can continue with your illegal connection.

If you have the "required" cleanouts on the exiting line, you can install a test ball to seal it. Testing will NOT tell if the vents and traps are correct. Only a visual inspection will show that.

A 'test tee'

will allow the insertion of a 'test plug'

Where I worked I had to do a water test on the DWV system. Put in the water until it ran out the roof vents.
That was always fun when there was no water on the job and I had to carry it to the job especially in the winter.
