Grey Water Tank Guage Reads High
Our 2017 Bambi FC 20FB seems to have a calibration or location issue with the grey water level. Capacities are 23/21/18 Fresh/Grey/Black.
When tanks are empty all read zero. When fresh water tank is down to 40% the grey water tank reads 100%. (Black maybe 20%).
I guess I can do some filling and emptying to measure actual capacities (like starting with empty tanks and adding 10 gallons to each and checking readings. However since it is obviously off, wondering what might be the problem and if there is a way to calibrate it, or of has somehow "slipped" out of position.
This is of course with no "city water" connection.
