AAV on a laundry sink pump

[Stephen Silver]

Can I use an AAV on a laundry sink ejection pump? Just to be clear, this handles gray water only.

No. An AAV is a one way check valve that allows air to flow only into the pipe. As the sump fills with water air has to escape from the tank. As the water is pumped out, then air is needed back into the tank.
