Question Hi: I hope you can make sense out of my questions
about my project. I have a small bathroom with tub, toilet and sink. It is still in the rough stage. The vents for the tub and toilet are each 2" ABS. On the right of those fixtures on the same wall is the sink. The sink drain must be "wet vented" since it does not have it's own connection to the ABS. The height of the sink 2" "wet vent (arm)" is determined by the code requirements for 'P' trap height and the wet arm will have to travel left 2' + - to join the 2" toilet vent in the same wall. From that same junction, the 2" will travel left 2' + - to the 2" tub vent in the same wall. Question: If you can picture my project, what are the fitting type, drain slope and height requirements of the pipe/vent/etc. throughout the above system including the toilet-to-tub vent pipe connection etc. I assume that the horizontal connection between the toilet and tub vents has to be higher then the "wet vent" so the sink waste drains only into the toilet vent pipe. This whole scene is also complicated by the window that is 1' + - above the horizontal vent sections. Make any sense of this? Your thoughts are much appreciated. Thanks, Larry
Answer Hi Larry, You can't wet vent the lavatory. That would build a "S" trap which is outlawed by all city and county codes. Run this past the inspecter. You run the vent off the lavatory. You discharge the toilet downstream fron the lavatory and you wet vent the tub into the lavatory drain. That eliminates the need for two vents unless your local code calls for a individual vent on the toilet. Make your slope,(pitch) 1/8 to 1/4" for each foot of run. More questions? I'm as close as a click. Good luck, Tom
