Our black and gray tank sensors are not giving accurate readings, the gray tank is stuck at 69%. It looks like what monitors the tanks are pressor sensors from Serta, "Setra Systems Pressure Transducer 2091001PG2M45P1". I have the CMP-20 monitor panel.
Although a little pricey to replace, I have no problem replacing them if it is a sure fix. Does anyone else have this setup in their coach and had success changing them?
I tried to have the tanks hyro-cleaned to see if the sensors were plugged but he was afraid his pressor nozzle would ruin the them. I've located the sensors behind the wet bay partition, a little tight to get to.
Thanks, Steve
