Hi - I don't know if this should appear here or in 'Plumbing Code Question' forum so let me know.
I'm doing a kitchen remodel and am planning the DWV plan. The standard appears to be to use one san-T in a vertical vent drain configuration and one p-trap connected to the two basins and disposer. This is what the old sink location had and I've seen plenty of on these forums.
For the new location I was thinking of using two san-T's, one right above the other, say at 13" and 16". This would allow a seperate p-trap for one basin and another for the disposer and second basin. Is this allowed? I did an extensive search here and on the internet and didn't find much. Although it is possible to use a double TY and spread the to drains horizontally (which I did see posted here by Terry) there really isn't room for this and I'd just as well revert to one san-T. It just seems have each sink with it's own trap would be more reliable and easier (after the rough-in is done).
A secondary question as well: I've been searching for the code requirements regarding the kitchen DWV pipe size. Is 2" required? This is somewhat OBE since I think I'll use 2"" anyway to be safe - but it would be good to know. What about a 2" drain and then necking down to 1 1/2" about 6" above the fixture flood line?
P.S.
I had trouble logging into my old handle (Earl001). I didn't know where the password reset was sent to so I had to create a new account.
