Re: Waterless traps
I was informed by Advanced RV that they have been using the Hepvo valves for some time and that they work well. I didn't even know these things existed. When I saw the title my thoughts went to the waterless urinals with oil traps. In my former job we experimented with those.
I know from experience regular plumbing traps in an RV lose their water quickly as I imagine a combination of heat and jostling expedites it. It is probably a weekly maintenance chore to make sure the bathroom floor drain is trapped with water if you don't use it with a shower or if you just had a rather bumpy drive.
