My system needs an AAV as the point at which the 22mm pipe joins the drain is about 3 meters below the position of the saniflo. This causes suction and pulls the water out of the sink and bath traps which in turn creates a smell in the bathroom. Fitting an AAV would stop this as any suction...

Did anyone come up with a solution for the 22mm air admit valve. Thanks

I have fitted a saniflo system in a house i am renovating and have found i need to fit an air admit valve. As the discharge pipe is 22mm copper does anyone know where i can get a 22mm air admit valve that would do for a pressure system. Thanks
