: I'm want to install a sewage ejector in my basement,the drain to the ejector is what size,if i'm installing a sink where do I vent to, What is the proper pitch for venting and draining .Is there any place I can get some information on installing a ejector??
The drain from the ejector is 2". You need to vent the lift can and all the fixtures. The vent should be 2" on the can and 2" on the toilet, 1-1/2 on the lav and shower. The vent should terminate out the roof. The vent can be level or so graded as to drain back to the fixture it serves.The drain line needs to have 1/4" per ft grade on 3" and less and if needed 1/8th on 4" and more.
