How does a sprinkler pump relay work?
A pump relay acts like a switch that the controller can turn on to provide power to the pump. Since the controller outputs 24Volts AC power, and most pumps require anywhere from 110-220 Volts AC, the pump relay acts as a step-up transformer to route additional power to the pump and activate it.

How do you know if your pump relay is bad?
If the coil or contacts on the pump start relay are bad then the pump will not run. Likewise, if the irrigation controller is not sending that 24 VAC signal to the pump start relay, then the pump will not run.
Why is my sprinkler pump not turning on?
If it isn't turned on or if it's tripped, you may just need to reset it. If you reset a tripped breaker, and it continues to trip you may have an issue with the wires running to the pump or the pump motor itself — or some other issue that's causing your pump to get too little electricity – or too much.
Why is my irrigation pump turning on and off?
If the water pressure is too low, the pump turns on. If the water pressure is too high, the pump turns off. This process of turning on and off is called cycling. Unfortunately, cycling can be very destructive to a well pump because it shortens the life of the motor and puts excessive wear on the control components.
What is a well pump relay?
The well pump relay switch is used to turn on and off higher horsepower well pumps. The pump pressure control switch operates the pump relay switch that in turn operates the pump.
What is a pump relay switch?
A pump relay switch is used with higher horsepower submersible pumps and signals to the pump when to turn on and off. Pump relay switches can be thought of as buffers between the pump pressure control switch and a heavy-duty water pump.
How do I know if my well pressure switch is working?
Then Check the Pressure SwitchYou'll find the pressure switch mounted on a 1/4-in. tube near the pressure tank. ... Remove the cover and bang a screwdriver handle sharply against the tube below the switch to jar the electrical contacts.If you see a spark and the pump starts, the pressure switch is the problem.
What is a pressure switch on a well pump?
Pressure switches monitor your water system to electrically “start” or “stop” your pump at pre-set water system pressures. Pressure switches are used on submersible, reciprocating and jet pump systems. In a well system, pumps are used to bring water from the well and to pressurize the piping system in the home.
What is a water pump relay?
Water pump relay switches control the operation of the pump's electrical motor . The relay itself is remotely controlled by the water system pressure switch. Typically, the relay is employed when the pump's load amperage exceeds the pressure switch's electrical capacity. Damage can occur to the pressure switch's electrical contacts by excessive amperage. The physical installation of the relay switch should be in a dry location. A high moisture environment can cause a premature failure to the switching mechanism and the electrical contacts.
How to mount a two pole relay switch?
Mount the two-pole pump relay switch in a dry area, preferably 5 feet off of the floor. Use the vendor provided mounting screws to secure the switch mechanism to a solid wall with the screwdriver.
What is the second wire on a 220 VAC pump?
The second pair of wires will be coming from the main panel electrical source or power feed. A 220 VAC pump will use a two-pole circuit breaker or two fuses. The last pair of wires connected to the relay will be going to the pump motor itself.
How many wires are in a two pole relay?
Understand that there will be three pairs of wires connected to the two-pole relay switch. The first pair of wires will be tied to the relay's control coil. The coil produces a magnetic field that operates the relay's electrical contacts. The second pair of wires will be coming from the main panel electrical source or power feed.
How to reenergize a main power?
Re-energize the main power by turning on the circuit breaker or reinstalling the power fuses.
Step 1
To prevent electric shock, turn the main circuit breaker switch to “off” prior to making any electrical connections.
Step 2
Assemble conduit piping and connect AC power from the power source to one side (LINE IN) of the relay.
Step 3
Assemble conduit piping and connect wiring from the pump motor to the other side of the relay (LOAD OUT).
How to wire a pump relay?
Route the wires from the control box to the pump relay. If desired, use wire clips to attach the wire discretely to the wall so it is out of the way and visually unobtrusive; these are found at any hardware store and have a small nail attached to a plastic clip that is hammered into the wall to hold the wire in place.
What voltage is a relay for a pump?
The wire from the power source to the pump relay, as well as the wire from the pump relay to the pump, needs to be rated AWG 12 and will be used for a 120-volt or 220-volt current, depending on the pump model. Make sure to use a relay that is compatible with the voltage of the pump.
Can you use water from a river for irrigation?
Check with local authorities regarding the use of water from rivers, lakes, streams and artificial impoundments for irrigation purposes, as property owners do not always have the right to use the surface water that passes through their property.
Can you use a pump relay box in direct sunlight?
Do not mount the pump relay box in direct sunlight to prevent overheating.
How far from the timer should a pump start relay be mounted?
Pump start relays must be mounted at a minimum of 15 feet from the timer and pump to avoid electrical interferences that cause malfunctions. When a pump is to be operated by the controller, a pump start relay must be used. To connect the pump start relay:

Why is it dangerous to replace a relay switch?
Because power being on while installing the relay switch is extremely risky. This might eventually force you to replace the well pump later on.
How to tell if a well pump is tripped?
Answer: Ensure the well switch near your pressure tank hasn’t been turned off first. Then look to see if the well’s double-pole circuit breaker has tripped. If it has, it should be reset. A breaker that is constantly tripping indicates a problem with the well pump. This requires the assistance of a professional.
How to clean a pressure switch?
Answer: Start by cleaning and inspecting the switch relay contacts. Look for burning or pitting on the surface of the four contacts afterward. If the pressure switch shows symptoms of wear, it may need to be replaced. If not, sand it down with fine-grit sandpaper. This will aid in the removal of any dirt or debris, revealing the gleaming metal.
