So ive piped to the tank that contains the pump, it will be draining a washing machine and laundry sink. The inlet and exit are 1 1/2. So i will vent to the stack vent, but the drain is where im unsure of the best course of action.
Should i ..
A. Pipe pump exit up and to the drain for the shower ? This is a 1 1/2 pipe
B. Pipe pump exit to the main trunk that is a 4 inch pipe? And then should there be an aditional gas trap if located in the drain? Or will the pump check valve serve this purpose?
