I bought a steam generator for a steam shower that I am constructing. It sits in a "Smitty pan " for leakage or overflow that allows a 3/4 pvc outflow pipe.
The only place I can drain this is into a nearby drain stack that the sink empties into.
because pan should never have water in it I can not use a p-trap so I need a way to prevent the return of sewer gas in this open system.
I thought about a horizontal one way gravity closing valve but I am not sure this would close completely in a zero pressure situation.
I foung a device called e-z tap on the web which is basically a trap using a ball that sits in a cup blocking sewer gas. I have recreated this "waterless trap" using pvc pipe and a superball and think it will work well.
Does anyone have any other comments or suggestions?
Thank you
