I built 2 gray water tanks to fit in my 64 Overlander. I kept hearing about the terrible reviews on tank monitors, and decided I didn't want to deal with it. However, I'm looking at a camp site that offers electric and water, but a dump station. Now, I don't know when the gray tanks are full until they are over loaded.
My thought is this: I have the 2 tanks side by side, and they both have vent pipes coming out the top, tying into the kitchen vent pipe. I had to drop them once, so I cut the pipe and have the rubber fittings on them. No big deal. What I'm thinking about is using an aquarium float sensor. Drop it down into the vent pipe, then drill a tiny hole for the wires to come out and then seal that. Hook that up to my 12v system, and basically, when the float comes up, it just turns on a 12v LED to let me know my tanks are full. I won't get a gradiated system, but I could set it when they are 75% full.
Any thoughts? It would cost me about $15 for the whole deal.
