Venting for sink pump

I want to install a sink in my basement. It is close to where the sewer line exits the house. The pipe exits 36" above the floor, so I was planning on using a sink pump from Flotec. Do I need to vent the pipe from the pump to the sewer main or can I pipe in directly.

Welcome to the forums! You may be able to get by with a studor valve (air admittance valve), mounted a little higher than the exiting lateral pipe. The pump may move more water than the sewer pipe can handle without admitting air above the water column.

if the pump you plan on using is enclosed in a sump (or tank) then you'll need a vent for the line entering the sump and you'll need a vent for the sump itself. i suppose you could use a autovent for the drain line but the tank needs to be vented to the atmosphere due to the waste water that is held in the tank, you don't want those odors in your basement.
