fresh water tank filling system
I fill our fresh water tank about twice a week. I do this before travelling, to prevent instability from a partially filled tank. I also use tank water for showers, as we often stay at a farm where the water pressure is very low. The pump gives a much better pressure for this. When boondocking, we need to top up every few days. I find the filling procedure to be inefficient. The filler point is on the opposite side to the mains water connection. A hose has to be passed under the stabilizing jacks to avoid kinks, and the end of the hose has to be plugged and unplugged to prevent dirt from entering the end of the hose. Kneeling in the dirt, especially in the wet, is not my idea of fun. I have to find and install a fitting to allow the end of the hose to fit down the neck of the filler. To avoid this boring and messy task, I intend to buy a $15 water heater bypass kit, and install it as a "water pump bypass". When the two valves are turned to the bypass position, the city water will flow backwards into the tank, which has an air vent. When the panel indicators show "full", or I hear water overflowing out of the air vent, I can turn the bypass valves to normal flow. The bypass could include the in-line filter, but I probably won't do that. I keep that filter clean, so back-washing it won't put a load of dirt back into the tank, and I have a water filter on the outside city supply. Winterizing the bypass loop would be carried out by emptying it when the filter is emptied. Are there any aspects I haven't considered? Any reason why this wouldn't work?? Nick.
