Seelevel sensors
We have seelevel sensors on our Monaco, I put them in in 2012. Most recently, maybe 2 months, the gray tank sensor says 100 all the time. (when draining it goes to 95 for a bit, then back to 100) T...

Some years ago, we had a similar problem with external capacitance sensors (not SeeLevel) on a Class C grey tank. I dumped a full bottle of Dawn dish detergent down the kitchen sink and filled the tank to nearly full. After a 20 mile drive on some moderately rough back roads, I drained the tank and the level monitor once again read correctly. I haven't had the problem yet with our current SeeLevel sensors, but I wouldn't hesitate to try the same fix again. Other detergents may work as well, but I know Dawn works well in cold water and is a good grease cutter.
