Holding Tanks
a question regarding the holding tanks. I have a 25 gallon black tank, how much water should i add to it before i use it for the first time in our new trailer and whats the easiest way to do that?

For that size tank a couple of gallons should suffice, there is no exact amount really, some use a bit more and some use less, you want to have some water in the black tank at all times during the active RVing season.
