I have been trying to find a complete drawing of a water system from well to house that shows how the system parts all go together. That drawing would include items from the well, pump, pressure tank, holding tank, pump to house, filters, check valves and fittings using PVC piping. I am in the process of changing out my system that went from well to house (100 ft) to a system that will go from well to holding tank (300 ft 50 ft climb) and then to house. I am also trying to find a LOW VOLTAGE RELAY SWITCH that goes from 12 or 24 volt to turning on 240 volt for the 1 HP pump at well. I will have a float switch in the tank with the low voltage relay switch 300 ft down in the well house. There will also be a ½ HP pump from holding tank to house that will work off of a pressure switch. I want to run low voltage from holding tank to main pump to operate the 1 HP well pump. The pump house has high voltage 240, 30 amp breaker box.
