vents
Posted by Greg William on April 13, 2003 at 11:55:32:
I live in city that uses 1995 international plumbing code. I want to upgrade bathroom and limit vents running through roof. Currently have tub, WC, sink, and shower with one 4 inch and one 1.5 inch vent. From what I've found on internet I think I can use one 2inch vent (half the size of the 4 inch house drain). If trap distance to vent doesn't exceed 5 ft. for a 1.5 inch trap/drain; 6 ft. for a 2 inch trap/drain; and 10 ft for a 3 inch trap/drain. Am I looking at this correctly? I need a new roof this summer and went to limit number of vent pipes. Thanks.
