Getting my 57 Overlander stripped down to do a shell off and found this P trap under the shower drain. It also had a brass one way valve down stream. The valve is just a flapper with no seal or spring tension. Any one have any experience with this shallow P trap? Wouldn't mind installing in the new shower/bath tub we'll install.
I reinstalled mine. I replaced the flapper check valve with a new one because I was running forward to a new gray tank and I didn't want water sloshing back into the shower pan every time I accelerated. It doesn't need to seal tight, just prevent mass flow in the opposite direction.
Has worked fine.
Thanks guys I hadn't come across the hepvo valve so this helps sort out dealing with the sinks and not losing what little space is available. I will probably use the Cunningham on the shower with a hepvo past it, just to keep it on the trailer.
