SENSORS

[luvmydogs]

In a 23 ft travel trailer for about 6 months and the black water and grey water sensors are stuck at 2/3 for the last month. We tried some of the granular stuff from camping world but didnt do a thing. Any ideas of how to get sensors working again? Seems strange to us that both are stuck on the same reading when they are different tanks. Anywhere else I should look for a malfunction?? HELP!

I have had similar problem, solved by letting the tanks dry out. Kind of nasty but once home I put a five gallon bucket under the dump value open them up, usually don't get to much out, leave it open a couple days and dry's out the tanks. Condensation is the issue I believe, may not be the best way but it works if you are suffering from condensation on the inside of the tanks.

They very seldom work.
Debris gets on them that is hard to get off.
I use dish soap to aid in cleaning them. Doesn't always work! I put the soap in while we are traveling. The sloshing cleans part of the debris off.
