For some reason the kids tend to throw used TP in the bathroom trash can.
Real problem. Get one to stop and another starts doing it.
Ugh!
If you aren't lazy and will dump the BW tank frequently, you won't be likely
to have problems. Fill the tank with water when it is less than halfway full
from flushing, and dump it. My tank looks almost squeaky clean and the level
indicator works fine (24 yrs old). Of course this is when you're in a park
with water and sewer connections at site.
