plumbing advice

[indyjps]

need some help on this one. wanting to put lift station in basement for bar sink and hopefully urinal. i think i can run it all with a grey water pump if its vented correctly with the rest of the house. what size pvc is required to run up to attic to tie into existing "stink pipe"
can anyone suggest a good plumbing message board if we dont have any licensed plumbers in the house. thanks

1 1/2 is all you need for vent With 4 DFU and less then 50' (UBC) I believe. Wisconsin has its own plumbing code so it might be A little different. Pit needs to be 30''X18'' min ,pump should have 2'' out let by code here...there again could be different there.

trying to avoid the pit, thinking if the sink is mounted normal ht in counter and urinal is mounted, well, crotch high i may not need to bury it.
