Has anyone seen an effluent or brown ejector pump with an inch and a half discharge? I have only seen these with two inch discharge pipes.
The reason I ask is that we have that we have recently performed an inspection with a basement bath and overhead sewers. The toilet is draining into an vented ejector pit. The vent pipe is 2 inch, and the pipe above the check valve is 2 inch but the pipe from the pit and the pump is only 1 1/2 inch.
The municipality says they have provided the certificate of occupancy but I still believe the pump is potentially wrong.
