thanks for all the great help - I think you got it. It is on the bottom of the fresh water tank. Why would they have a separate drain for the fresh water tank? I would have thought the low point drains would cover it. I turned off the faucet and the water stopped.
Low point will only drain the lines while a separate drain for the tank ensures you get every bit of water beyond what the pump will pull out. Also makes it easier to drain after sanitizing.
Camping buddy's fifth wheel has what looks like a 1 1/2" drain valve. Dumps the tank in seconds. I have a 3/8" petcock to drain my tank. I open it and come back the next day to finish what I was doing.
