You cannot use a cheater, studdor or mechanical vent or an AAV on any Saniflo product. As they are considered one way vents, they only allow air to flow one way. Saniflo pumps must have an 1 1/2" vent pipe vented to the open air, air must flow in and out of the vent pipe at all times, otherwise the pump will short cycle and the solids will not leave the toilet. You will have to flush it several times to get rid of the waste and eventually the motor will go bad. Make sure is vented properly.

This system can be put on a studor (AAV ) vent if vent can not be reached.

Any approved vent through Lowes , Home Depot or any plumbing supply house. Are allowable to use per plumbing codes in all states.
