Review: Good product although a little expensive for the application
Review: The gray water tank on my class A RV was smelling terrible. It was getting inside the living area and making everything smell terrible. I couldn’t find a leak anywhere. When I looked at all the connections and the tank, the only thing I could find was how this pipe went into the top of the tank, there was no rubber connection with clamps. That seemed very suspicious to me. It just appeared to be stuck into the top of the tank, and sealed in there with what appeared to be plumbers putty. I called the manufacturer and asked if this was how it was supposed to be. I would purchase a rubber connection if it was available. They said they are still doing it this way and if they have a problem to use a Sikaflex gray compound. I purchased a tube, and although the pipe comes out of the top of the tank I used the self leveling compound. I started applying it above the suspect area and let it flow down over the existing stuff and let it flow onto the top of the tank. It actually made a very nice looking cone shaped seal. By that evening, I could tell the smell was getting better. It’s been about two weeks and you can’t detect it in the RV anymore. I have aired out the basement in the RV and that seems fine now too. I would highly recommend this flexible sealant. It’s amazing how flexible it is and how well it sealed this connection. We suffered with the smell for years until I had checked every fitting and the tank. The only thing left was this connection, but it appeared fine. The crack filling abilities of this self leveling system must have flowed into the source of the problem! Best ten bucks I’ve spent in a long time!
