Gray water tanks!

[kvsoccer5]

Have a 2019 Thor Miramar with two gray tanks, kitchen and bathroom. Is there a way to clean out the tanks as sometimes the sensors may be covered by soap/dirt and do not show up on the digital display showing the tanks empty when they are actually full! ty

Most RVs have the opposite problem with their tank indicator systems: they indicate higher than the actual level as the sensors get "shorted" with debris. I would think your problem may be more likely related to a poor wiring connection problem.

I wouldn't spend too much time, worry or money trying to improve the accuracy!! I've owned several RVs & never had one that the those sensors were of any useful information after the first couple times the tanks were filled.
Your kitchen/galley tank will out last the others unless you run excessive water doing dishes.
You'll know the bath tank is full when it backs up into the shower, usually about the time you get all lathered up & is the tank that will fill the quickest. Usually I leave the bath tank valve open when connected to sewer so not dumping every other day.
The toilet has a very distinctive burp/gurgle when that tank is nearing full.

NEVER leave the black tank open. Water will run out and you will build a poo pile in the bottom of the black tank that will dry like concrete!

That should've read the the bath grey tank valve.
TOTALLY agree!
NEVER EVER leave the black tank valve open, dump when needed!
