- Step 1 – Disconnect All Power.
- Step 2 – Ground the System.
- Step 3 – Make the Wiring Connections.
- Step 4 – Test the Pump Before Installing.
- Step 5 – Mount the Control Box.
- Step 6 – Install the Pump.
- Step 7 – Clear Out the Well.
- Step 8 – Attach to Water Tank.
What is the difference between a 2 wire and a 3 wire well pump?
The main difference between 2 wire and 3 wire well pumps is characterized by where the starting components for the motor are located. Three wire well pumps house the starting components (starting capacitors, running capacitors, relays, and thermal overloads) in a control box or panel.
Do you need a control box for well pump?
A well pump control box is essential in that it protects submersible well pumps from: Too high or low voltage. Clogged well screens. Malfunctioning motors and pumps.
Does a well pump need a neutral?
Neutral (white) isn’t used in this kind of circuit. Ground (green or bare) is necessary for safety. It sounds like the cable that was used to wire the pump had a white wire instead of a green (or bare) one.
What type of pipe is used for water wells?
Poly pipe is fast becoming the most common and efficient way to install a submersible well pump. With most well depths up to 350′ the 160psi HDPE Black Poly Pipe shown below in green is the top choice for well pumps and solar well pumps.
Do well pumps need a control box?
Why Is a Control Box for a Well Pump Important? Well pump controllers usually have microprocessors that monitor power-line pump and voltage motor power draw. A well pump control box is essential in that it protects submersible well pumps from: Too high or low voltage.
How many wires does a well pump have?
In a 3-wire well pump configuration, the motor is connected by a black, red, yellow, and green (ground) wire. Three-wire pumps utilize a separate control box outside the pump that houses the important starting components, which is usually mounted on a nearby wall above the ground.
Why does my well pump need a 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.
Does well pump need to be grounded?
It is recommended that all well pump motors have the ground wire connected to the same service ground as any other motor would be. Grounding is a safety issue and offers protection from electric shock or electrocution due to leaking current.
Should a well pump be grounded?
NEC 250.112(M) requires that where a submersible pump is used in a metal well casing, the metal well casing shall be bonded to the equipment-grounding (bonding) conductor of the circuit that supplies the submersible pump.
What size pipe do you need to pull a well pump?
It uses 3/4″ threaded pipe. To make one of these wrenches you just go down to the local hardware store, buy the threaded pipes and put them together. The long pipe (the one that goes down into the hole) needs to be at least 5′ long if you want it to reach.
What size pipe do I need for my well?
Use a pipe that is at least a schedule 80 in wall thickness. The heavier-walled pipe can withstand the stress of a submersible pump. Use the required diameter of piping that is called for by the pump’s manufacturer. This can range from 1 inch to 2 inches in diameter.
