More newbie question..
I read in the FAQ's that you must male sure there is water in your black water tank vent trap, to prevent odors in the coach. The post didn't elaborate on how one is to do that.
So after you dump the black water tank do you always add some fresh water to it? If so, how much is usually needed to fill the vent trap?
Wandering the RV parts store the other day, and I spotted these tank cleaning wands. There were a few different types, and a range of prices. Are they actually a good investment, and if so, what type is the better one to go with?
Would the use of these help prevent failure of your in-tank monitors, or could they potentially cause damage to them?
Would you use these wands at full water pressure?
Is it best to use a wand each time you dump the tank, or is it more a yearly maintenance thing?
