So, I have taken my residential test twice now, and I failed! I have done well on everything but the waste and venting portion. I am beginning to believe there is something I'm just not getting, or maybe there is a sneaky trick to the test. Anyways, I would like to know how many 1.6 gravity tank toilets can be put on a 3" drain, (private/public)... and how many flushometer valve toilets can go on a 3" drain, (private/public).
