Would just like see what others have experienced.
We have 2 black tanks, the sensors on either have never work correctly more or less since we received it Nov 2019
we used every trick on here and the net.
Just tried this, Unique Sensor Cleaner Liquid, filled both tanks to top with hose, let it sit for days. didn't do squat!
even when ours says are full on screen, still a 1/3 of empty tank.
