Capt Jim, For boat cleaning I dip into the river with a
bucket. And I fill my water tank with the melt water from the jugs of ice I bring down. We use only about 4 gallons of tank water per day. Melt water is for drinking and cooking, river water for first rinse on dishes, tank water and soap for wash and rinse. For hot water we boil tank water and store in 2 quart commercial coffee thermoses, one in the head and one in the galley. Pressure water is cold and pumped from the tanks into a 5 gallon stainless steel garden sprayer tank that I pressurize by hand pumping. Even if we leave a faucet running we can't lose more than 3 gallons.
