Gray and Black tank sensor issue

Hello everyone,

My wife and I have a fleetwood Bound 2010 35H and our black/gray sensors never show empty. Actually the black tank shows full and the gray flashes 2/3 to full even when the tanks are emptied

And they never will show empty unless you get very lucky.

The "Sensor" is basically a nail (Technically it is a metal rod) stuck in the side of the tank. if the side of the tank is "Slimed" then the nail is wet all the time and thus the sensor does not show empty.

There are several possible solutions

HORST miracle probes These are still "Nails" but they have some added features and are advertised as being immune to the problem above.

Pneumatic sensors (Pressure switches) I"m supposed to have some but I don't (long story) these work..... on pressure. they can also fail.

See-Level sensors. DO not have them but everyone I've spoken with who does says very nice things.. These work..... differently.


What can you do with the existing sensors
Cleaning the tank (Geo method) has worked for me so has "Blasting" the sensor wall with a home made version of the Valtera Master Blaster tank cleaning wand... But not often

Haveing the tank professionally steam cleaned would work but is expensive.

I'd suggest the See Level system or what most of us do. Live with it.
