In this video, I give you a look at a replacement for the traditional P-Trap called a HepvO valve.
Being waterless it holds many advantages for RVers most important being less chance of waste tank odors entering the rig. It also saves space which can then be used for extra storage.
I’ll show you my installation of one under my kitchen sinks. As usual with RV mods, it wasn’t as straight forward an install as I hoped but I got it accomplished with a few extra plumbing adapters and elbows.
