I'm draining a utility sink to a sewage ejector pump. The 1 1/2" drain is dedicated to the sink; there is nothing flowing into it before it reaches the pump basin. The pump basin is vented 2".
I've heard that each fixture should be vented, but the only thing that could siphon the trap is the pump, and it has a vent. So, do I really need to vent the sink additionally?
