Tank Sentry

[cmillsap]

David,

There must be a virus going around. LOL! I had to deal with my black tank sensor always reading zero for 6 months until I could get to Marathon to get it fixed. My tank sensors are monitored through the TechLink system.

I always dump when I fill the fresh water tank

Since the fresh water and grey tanks sensors still worked, I just wrote a simple formula on my Excel to determine the black tank level (gallons) by adjusting the fresh water level (gallons) and grey water level (gallons) daily on Excel. With the family on board, you may want to adjust the levels more frequently! LoL!

IOW, as the fresh water gallons go down and the grey water gallons go up, the remainder gallons are in the black tank............. In order to make this work you have to pull water from the fresh water tank always and only use the shore water supply to fill the tank.
