Tank level gauges misreading

Hi,

I have level gauges on my RV (like everyone I assume) but they are currently misreading the correct levels.

Does anyone know how to clean the sensors? I have tried flushing my waste tanks.

How hard is it to replace the sensors?

  • Common sense on water usage will prevail over technology. don't waste your time & ' $ ' 'cleaning' the sensors. Even if it works for that time, it will not work for long.
    Know your tank capacities, educate your family on them, and the indications ( burping ) of a near full tank.
  • J-Rooster....I have used that product, but not exactly in the way you describe. I'm going to try that when I get home from my current trip. I've just added it with a bunch of water (maybe 1/3 tank) and let it slosh around while I drive to next campsite.
  • I've tried several of the suggestions on these forums and still, sometimes my sensors work and most of the time they don't.
  • I use RV Digest! 6 capfuls, then fill up your tank, let it sit 24 hours then flush! The principle behind RV Digest is the enzymes eat all the bacteria inside your tank, which also means it cleans your sensors. I've used it several times it works. My coach came with a built in oscillator inside the black tank so I rarely have those troubles. Good Luck
  • There are scores of monitor systems. Some use a probe INSIDE the tank. Some use glued on sensors on the outside of the tanks. BOTH can malfunction, but you need to know what type too see is flushing is the answer. We fill and flush a minimum of 3 times and then leave the valves open with the dump cap OFF to let the tanks dry out. Let the tanks dry for 48 hours and then see what the readings are. Doug
  • Hi,

    The only one that may work reliably is the fresh water one. If it is not reading correctly then cleaning is not likely the issue.
