Sewer Venting ?
Posted by Bob Whitemyer on February 11, 19101 at 07:09:19:
Problem: When washer or tub drains there is air pushed up into the down-line toilet(s).

Current setup:
(washer)=>20'=>(vent)=>(3')=>(kitchen)=>(5')=>(full bath)=>(5')=>(half bath)=>(5')=>(sewer pipe exits house)

I'm thinking I need another vent between my (half bath) and the (sewer exit) to fix this problem. Is there something I am missing or maybe more is needed.

Thanks in advance for your input.
