Gray Water Transfer

Most serious boondockers find that their gray water holding tank fills up before their black water holding tank. The obvious solution is to devise a way to transfer the gray water to the black water tank. Bobby Williams devised a nifty system to accomplish this. An added benefit is that the extra gray water in the black water tank aids flushing.

On my 37V, I cut the gray drain pipe and put in a Tee. I used a rubber connection, so it was easy to put back together. I got a 110v pump at Granger and use an extension cord to plug it in. I used a flushing kit from Camping World and mounted it at the top of the black water tank to transfer the gray water into the black holding tank. The cost was about $100.00.
