SENSORS
In a 23 ft travel trailer for about 6 months and the black water and grey water sensors are stuck at 2/3 for the last month. We tried some of the granular stuff from camping world but didnt do a thing...

Just had to do a black tank repair at the spin weld to toilet down pipe.....so I had cleaned/dumped the tank about 10 times. Before final install of toilet I put a mirror down there and could see (in my case) the sensors. They still had toilet paper mache on them and they had never given me problems. One of those wands with a hole squirting water out with a hose was the trick. Visually clean as a whistle afterwards.
Wand was like $12
