Isata 3 24FW cleaning black tank sensors

[hhl]

My black tank sensors started first reading 1/3 and last week 2/3 full after dumping the black tank. Ordered valterra master blaster tank wand.
Connected to water hose and held toilet valve open with my foot and lowered wand inside tank. Turned on water and rinsed driver side tank wall. Rinsed from left to right while lowering wand down into tank. 15 seconds of spraying
and sensors are working again.

Great tip! I wonder if you could get that down the shower drain and do the same for the grey tank? My grey tank sensors are wacky.

I couldn't get my black tank lights down to one. Before a 'boondocking' trip I dumped a cup of dishwashing soap down the toilet. When I returned home after 4 days after dumping the black tank the lights were down to one. Sloshing around with the dish soap did the trick. FWIW
