I have heard two opinions from two plumbers. One said adding a small expansion tank would help protect the well system, the other said the well's expansion tank would handle any back-pressure from the hot water expanding in the heater. Do I need to put a check valve and a small expansion tank at the inlet of the hot water heater?
The well system maintains good pressure at 55psi with a 50 gallon tank. I don't see any backflow valves in the current system. All the shutoffs are needle valves that have frozen open, so I will replace them with ball valves. I am also planning to add a sediment filter just after the pump, with a bypass loop for filter changes. My water is very hard which probably contributed to the water heater's death, so we'll also add a water softener as soon as we can afford it.
