I have a new water well with an 80 gallon pressure tank. I have installed a filtration system although all but 1 of 8 tested categories exceeds the existing county supplied water. I intend to place a backup water system in the well house in addition to the equipment that is now there (well house is 8 X 10 with 7' ceiling so plenty of room to work).
I'm wondering if I can connect my emergency system and run it at the same time as when the well is functioning normally (on grid). The way the emergency system works is that there is a T coming from the water supply pipe after the filtration system, that runs over to two 150 gallon water storage tanks. A T there allows water to flow into the storage tanks and both shut off when the water level rises by a "Hudson" Valve in each tank.
At the bottom of the tanks are the water exit valves which T together and the center of the T is connected to a 12V RV style demand pump. The demand pump is then connected back to the water supply pipe where it T's in just before the water exits the well house.
My question is this. Will I have to place a check valve on the water supply pipe "above" the demand pump feed or will the check valve in the well system suffice, and anytime the water pressure in the water supply to the house drops below 45psi, the emergency system would just be "supplementing" the water to the house?
