My valves were sticking the black tank. I seen this on a rv site and tried it. I was 100 shocked but it worked! I am purchasing another 2 bottles to keep.

We were struggling with a clogged drain and the Plummer suggested we get some drain lubricant. I found this one on amazon and thought I would give it a try. It has worked great for us. We have not had any issues (knock on wood) and I plan on continuing to use this product monthly. Anyone who has had clogged drain issues knows how not fun they are. I highly recommend this drain valve lubricant.

This is a very specific product for a very specific need. If you have an RV sooner or later you will need this. My black tank valve was starting to stick! Stuck open, stuck shut- either one is bad news. Put it down there once, helped a little, did it again - smoother! No miracle yet, but we’re going in that direction! I DO have video of the results, but absolutely no one should be made to watch it.

Very good product. I have used it for years. Instructions are clear. Simple to use. Basic RV tank maintenance lubricants for the valves on the grey and black water tanks.

This really workedJust like it said it would.Bothe black and grey water valves were almost seized.So since we're hooked up.I forced the valves shut.Poured the stuff down the shower drain and the toilet.Added some water and started working the valves back and forth little by little until they ran smooth as butter.
