Replace the grommet that connects your RV's 1-1/2" drain pipe to your gray-water tank with this durable rubber grommet. Grommet installs in a 2-1/2" hole in the bottom of your RV's gray-water tank. Rubber material won't rot.

Hi there. I'm Michael with etrailer.com. Today we're taking a look at the Valterra rubber tank grommet. This is a one and a half inch rubber tank grommet to be used with polyethylene holding tanks. It does require a two and a half inch tank hole. Once you have that hole made, you can simply push this down into the hole, making sure that the edges of the hole line up with this gap here, this ridge in your tank grommet.
Once you have the grommet in place, you can go ahead and install your drain pipe, making sure that it goes inside the tank grommet, and then you can seal it with a hose clamp. The hose clamp is not included with this product, however, it can be easily found at most hardware stores. The purpose of the tank grommet is to make that seal nice and tight so that you don't get any gases leaking, which could be unpleasant and potentially harmful. And that's going to complete our look at the Valterra rubber tank grommet.
