Wavin BV1B/UB HepvO Sanitary Waste Valve - 1-1/2"

Used to lower the show pan in RV and didn't have to deal with a ptrap.

This was perfect for under my RV shower. I had no room between the drain and the floor for a P-trap and this fit perfectly. So I didn’t have to cut an oversized hole.

For my RV. This is very well made , unlike the cheaper competitors I returned, it's not installed yet but already it looks lime a great idea. My pipes were taking up my cabinet space with this I will delete the P-trap and AAV

All of the parts needed were included in the kit with simple replacement instructions included.

Found out after buying my house that one of my mini split condensate lines was ran into the sewage which caused foul odor in the room. Use this as a condensate drain to prevent sewer odors from coming up since the condensate line goes straight into sewage. It was extremely difficult to find the pipes and connections to make this work since this is mainly for sinks. But the documentation says it can be used for condensate lines and so it is. Works great a little ugly but does the job. Amazing how little water it takes to flow down the membrane. Makes a very good condensate p trap solution.

This is the brand-name exact match replacement for the trap in our Lance camper galley sink. Easy install, perfect fit.

As a tester, this worked perfectly.

I have two Wavin HepVo sanitary waste valves in my converted Sprinter van. One that the builder put just before the gray tank, and one I put underneath the sink. I've been conversion is a very small living area and I don't have any smells from the plumbing system.I installed the second HepVo under the sink to save space, the builder had an S trap under there which took up way too much space and, because I had a shower pan in between the sink and the gray tank do it was possible to get a little backflow smell from that point. I did it mainly for space.
