    Black Tank Flush

    Does the water supply being used to flush the black tank need to be pressured regulated like the feed into the potable water supply at the Nautilus ?

    Would depend on the supply pressure. If if was reasonable (say 40 to 60 psi) probably not. We stayed in a KOA in Salt Lake once. The pressure at the pedestal was 100 psi. In that case it would definitely good idea given how delicate the water systems on these trailers seem to be.

    Thanks. Another question, I read where someone said they usually travel with 10 Gallons of clean water in their black tank. Is that a good idea and do you just put the water into the tank thru the flush valve at the Nautilus and just keep the dump valve closed ?

    It is a good idea, though you probably don't need ten gallons. I usually put Borax water softener and Dawn dish soap in with the water (search for "GEO Method" for more info) before traveling. The objective is to get a washing-machine-like action going to clean the tank and the sensors in it and my experience is that it probably works.
