This P-trap is perfect for an RV bathroom vanity. After watching YouTube videos, it can placed vertically and still stop angels from entering the RV.

Living off grid I have a grey tank under my kitchen sink and a compost toilet with a urine diverter. These are a must have for odor. They work great and last quite awhile.

Direct replacement for the HepvO valve that was in my 2020 Vanleigh Vilano 370GB shower. The old one was partially clogged and the seals had dried up at the couplings. This kit came with everything I needed to replace the valve and solve the leaks.

My van conversion didn't come with a P-trap so smells from the grey tank came up into the cabin. Not nice, not nice at all.

My under-sink plumbing was also a bit non-standard. It went straight from the galvanised metal drain into vinyl-braided tubing. Since the Hepvo is designed for standard PVC plumbing I needed to find an adapter. I found a marine supply company online that had one that fit, and that did the trick. Voila! A clean smelling sink.

Used this in the RV bath sink drain to help with smells and burps. Seems to help with them, it did burp once, and the pressure was so high, it leaked out of the fittings. With that known, I cranked them down extra, I'm gonna regret that later.
Want to install one in the kitchen, but not nearly as easy to reach.
Didn't have any install issues, pretty self explanatory. I installed mine vertical to lessen any cleaning or potential clogs.
Plan to get the kitchen when im motivated.
