TankWatch lights not lighting

Good Morning All,

We have a TankWatch monitor panel in our 1999 boat. It has three lights: Green for low, Amber for middle, and Red for full. After a pumpout, which we had about three weeks ago, typically none of the lights are lit. We add about a tablespoon of NoFlex Digester and flush it through to the tank. After a couple of uses, the green light on the TankWatch panel comes on. When the amber light lights up, we schedule another pumpout.

After more than a dozen uses of the VacuFlush heads, the green light is still not lit. It could be the Low sensor is just stuck. Could be some other power supply issue. We have made no repairs to anything in the vicinity of the holding tank, the heads, or the TankWatch panel in recent weeks.

Could someone please recommend a diagnostic methodology on tracing down the issue? I'd like to get the lights lighting up again.

Thanks.

John

Re: TankWatch lights not lighting

The senders are clogged with the animal fats in waste. The shortest route to making 'em work again is, remove the device from the tank and clean the senders by hand with a strong solution of detergent and water.



Better yet, leave the sending unit in place and replace it with tank level monitor system that uses senders attached to the OUTside of the tank. You should be able to keep the TankWatch wiring. Take a good look at the SCAD system Scad Tank Monitors

That Scad system does seem to be better. I'll have to keep that in mind. Thanks. In the meantime, I might have a messy job this weekend.
