Black Tank Valve Replacement
It seems every 2 years I need to replace the valve on the black tank because it become very difficult to pull. What am I doing wrong that causes this to happen?

One way that works for us that I do about once every couple of months.
Dump tank; dump a five gallon bucket of water through toilet, close dump valve and pour in about a pint of cheap vegetable cooking oil (canola) and then wait a few minutes to let the oil float on the surface of the water that remains. Next go out and work the valve open and closed as rapidly as you can. Valve gate will pick up enough oil after five or six open and closes to make a surprising difference. Works for us for a good twenty years so far.
