What is the purpose of a well pump control box?

The pump control box turns the well pump motor and the Electrical Outlet on or off when the water level control box signals it. The Chlorine Feed Pump runs when the electrical outlet has power, adding chlorine solution to the source water entering the reservoir.

Can you run a well pump without a control box?

But it is not the fact that the pump comes on every time you use water, it needs to do that. A high electric bill from a pump would be because the pump is running when you are NOT using water, or if the pump cycles on/off rapidly WHILE you are using water. Nope, a 3 wire won’t run without a control box.

How do I know if my well pump control box is bad?

Some of the most common indicators of a faulty well pump and pressure tank include:

  1. Fluctuations in water pressure throughout the home.
  2. Strange noises or rapid clicking sounds coming from the tank.
  3. Spitting faucets.
  4. Scalding shower water.
  5. High electric bills.

Are well pump control boxes universal?

However, one major manufacturer makes its own motor and control box, which are not interchangeable. As for the others, motors and control boxes may be interchanged as long as horsepower, phase, and voltage are a match.

Does a well need 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 do you bypass a well pump control box?

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.

What is the difference between a 2 wire and a 3 wire deep well pump?

The difference between a 2-wire and 3-wire pump is based on the type of motor that is used. It is called a “3-wire” due to the three “hot” leads, though there are actually four wires when you count the ground wire. The 2-wire motor requires no control box because is does not use a starting capacitor.

How do you know if your well pump is frozen?

If water pressure is low and little or no water comes out at the faucet, it’s a good sign of frozen pipes. It’s important to thaw pipes right away to prevent cracks.

Should a well pump be on its own breaker?

Yes, well pumps should be on a dedicated circuit.

How does 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.

Will a well pump start with a bad capacitor?

Without a functioning capacitor, there’s no way to get power to your pump’s start winding and the pump will not start. To check the control box, first locate and switch off the breaker that powers your well pump. If the capacitor is indeed leaking, it can be easily replaced.

Where are the control boxes on a well pump?

Well pump control boxes are used with 3-wire well pumps. Deep well control boxes contain the starting circuits for the pumps–the starting components for the well’s motor. These control boxes are mounted on a wall above ground, outside of the well.

Where are the check valves on a well pump?

Check valves prevent back-flow of water through piping for any of several reasons such as preventing loss of well pump prime by a check valve located at an above-ground water pump or at the water pressure tank – Electrical Power (Labeled SW in the sketch at page top) – Electrical switch at the water pump.

How does a pressure switch work on a well pump?

When the water tank’s pressure switch detects low water pressure, its switch closes, which turns on the electricity to the control box. Once the water pressure reaches the switch’s high-pressure limit the switch opens, turning off the electricity. Well pumps with control boxes have start and run circuits.

How does a well casing vent work in a well?

A well casing vent can be seen as the vertical copper pipe which forms an upside down “U” shape and is connected to a fitting on the cover of the well casing. This well vent permits air into the well during water draw-down during pump operation. Details about well casing cap vents are
