Black water and gray water gauges switched

[RV Girl]

In my Thor Gemini 23TR, when our kitchen sink fills up, the gauge for the black water registers full, not the gray water. One of the gray water gauges appears to measure the black water level.

The simple option is to relabel them. If you want them to be correct, and the tanks are close to each other it is a simple task to unscrew the harness from the side of the tanks and swap them (provided you have easy access--those are usually underneath the coach).

I dump both tanks every 4 days as I have figured out that with 2 of us it takes about that long. As for the useless gauges the read how they want. My other rv were the same no matter what you did to keep them clean. They read wrong after the first outing. There was a site that told about differences in bath wipes but the video was removed.

I agree: re-label them, and the problem is solved!

Make sure your kitchen sink doesn't drain into the black tank. Thor's drawings, show both the bathroom sink and the kitchen sink draining to the black tank in our Gemini. When I tested it, turns out the bathroom sink goes to the black tank, kitchen sink goes to grey, which works much better for us, but is not as the drawings show.
