need advises: plan to add a new 2nd FL bathroom, but main stack is 30' away...
Hi, all, any advise is appreciated.
Do I just use a long 3" pvc to connect the main stack? or dig out the basement ground to make a new stack?
If I choose the long pvc option, slope drop would be 1/8" per foot times 30 feet= 6.6', right?
