Testing Drains
 
I roughing in drains to a new construction basement project. Is there a method to test the drains? The toilet flanges have plugs installed in them and I'm not sure as to wether or how to test the drains. I'm following the IRC book, but it's a little vague on things. bjr23

one way is to pull a long water hose onto the drain and turn on the water... you need to remove the cover of the toilet drain of course....

Pressure test them? Yea, they make plugs for all points (vents, main stack, etc) as well as a pressure gauge and fill point. I have never bothered because working with PVC is so easy.

You test all new drains, thru roof vent or to the point it connects to exitsting vent, test from take off for new drains using a test tee, then use a cherney test ball in the test tee filled with air, after that fill lines with water.

gee, didn't know or didn't understand it's that complicated to do the test... all I did in mine is use the water hose method and assuming vent are all working...... didn't know it has those test balls...etc...

Thats why we do four years of school. This test is required when new plumbing goes in and needs to pass an inspection.

All the PVC is supposed to be pressure tested (5lbs for 15 minutes) to make sure nothing's been missed - such as unglued joints.

I used my wash machine for three months on the plumbing I installed and no problem... they are ABS types... well for residential rough in... that probably extremely low chance of anything missed glued as they are underneath the concrete anyway... thanks for the knowledge though...

I don't know, I recently removed a partition wall in my basement... a stud fell on my shoulder as I was removing it. It had never been nailed in. All the others were toenailed but this guy was just sitting in place, tightly fit, but all it took were some hammer vibration and it nearly cranked me in the skull... somone forgot to nail it in, I guess you could forget anything. Especially pvc pipe where so much is dryfit and glued in sequence, its very possible.

well I then consider myself lucky and/or keep my finger cross no future issues/problems....

Another facet to this is a lot of localities require purple primer to be used on PVC, as a quick visual inspection that joints have been glued.

Obviously it doesnt' take a genius to figure out how that doesnt' have a 100% guarantee either.
