Fresh Water Tank Leak
Well, this turned into a bit of a cluster. It turns out the metal insert that the screw for the wire goes into was leaking. This is a spin in style sensor. So I pulled out the insert and enlarged the small hole to accept a 3/8Ē rubber sensor. Installed the new sensor and thought I had it cured. Nope! Still leaking. Well the area where the metal insert was (that is part of the spin in sensor itself) is thicker than the tank wall. Therefore the rubber grommet would not mushroom out to make the seal. I know, itís hard to explain. Anyway just know that drilling the hole in the spin in sensor bigger and installing a new sensor does ďnotĒ work. I had to plastic weld the hole closed. I used some polyethylene flat rod from Amazon and my HF Tools hot air plastic welder and closed up the hole I drilled. Then I drilled a hole beside the old one and installed my new sensor. Problem solved.
