Hi,
I'm designing the basement finishing and have an interesting problem. The builder put in an ejector pit, stubbed bathroom, drain extension, vent extension, capped water lines etc. on the upper left side of the basement. My wife wants a full kitchen on the right side.
Using a pump to push the sink & dishwater wastes is actually easy since the existing kitchen is right above it and the drain is easily accessible in the basement ceiling for a pump to push it up.
The problem is the vent for the pump in the kitchen. Since the kitchen above only has a sink and dishwasher, the builder put an AAV (to code) in the drain. So no vent to tap into. I know I can't use an AAV here since the pump needs to pull/push air.
How can I run a vent line 50+ feet to the vent at the ejector pit?
The joists run north/south (assuming the top of the picture is north). They are 12" high I beams, so getting a pitch that long would be hard/impossible. All the plumbing runs from the lower right, across the wall then under the stairs to the sewer in the upper right, so the rest of space on the bottom is pretty open.
Thanks
Chris
