Shut off electricity to the pump at the breaker box. Remove the screws on the box holding the pump control. Remove the box from the wiring attached to the back of the control plate. Loosen the screws holding the two wires to the back of the control knob or switch.
Do all well pumps have a control box?
Two wire well pumps do not use a control box. All the elements already come built within the motor or pump house itself. This allows for easier installation. However, if any of the starting components fail, the pump will have to be pulled up and the whole motor will have to be replaced.
How does a well control box work?
The main job of a well pump’s electrical control box is to cycle the pump’s pressure switch on and off. In a private well system, the pump draws up water from the groundwater supply and pumps it into a pressure tank. The pressurization that occurs inside the tank provides the force that gives a building running water.
How do you test a well pump control box?
Turn a multimeter to the “Ohm” setting. Touch the multimeter’s probes on the capacitor’s terminals and watch the meter’s reading. The meter should reach infinite, fall back slightly, then reach infinite again. If it does not, then replace the capacitor. Replace the wire connectors after testing the control box’s capacitor.
What do I need to know about my well pump?
Gauge (Label #3) – Water tank pressure gauge. The water pressure gauge on home water systems is one of the most helpful and simple devices used in diagnosing poor water pressure and pump, well, or pump control problems. This gauge has broken cover and needs replacement.
What does the control box at the bottom of a well do?
Control box with pressure switch and disconnect regulates supply of power to the pump motor at the bottom of the well. Many people assume that the well cable is made up of two hot legs with a neutral; however, that is not the case. The red is start, the black is run, and the yellow is common.
What to do if pressure switch on well pump is leaking?
Feel under the switch housing for leaking water or water leaking from the mechanism itself. If water is leaking under the switch’s plumbing connection, fit the jaws of the plumber’s pliers on the brass fitting. Turn the switch one revolution clockwise to tighten it. If water is leaking from the internal mechanism, the switch is bad.
