The Ultimate Guide to Resetting Your Well Pump Pressure Switch

As a homeowner, you rely on your well pump to provide a consistent supply of water for your household needs. However, if your pressure switch malfunctions, it can cause disruptions to your water system, leaving you without water or with inconsistent pressure. Fortunately, resetting the pressure switch on your well pump is a simple process that can be done with a few basic tools and some knowledge of the switch’s function.

Common Causes of Pressure Switch Malfunctions

Debris buildup on the switch contacts is one of the most common causes of pressure switch malfunctions. Over time, debris such as dirt, dust, or mineral buildup can accumulate on the contacts, causing them to stick together or become less conductive. This can result in inconsistent pressure readings or the pump failing to turn on or off properly.

Another common cause of pressure switch malfunctions is corrosion or rust on the switch contacts. Exposure to moisture or humid environments can cause the contacts to corrode, reducing their ability to conduct electricity properly.

Broken or damaged pressure switch components can also cause malfunctions. Over time, the components of a pressure switch can become worn or damaged, causing the switch to function improperly.

Finally, power surges or electrical issues can also cause pressure switch malfunctions. When the power supply to the well pump is unstable, it can cause the switch to malfunction or fail altogether.

Signs of a Malfunctioning Pressure Switch

It is important to know the signs of a malfunctioning pressure switch so that you can identify the problem early and take corrective action before it causes damage to your well pump. Here are some signs to look out for:

The well pump is turning on and off frequently: If the pressure switch is malfunctioning, the well pump may turn on and off frequently, even when there is no water demand.
The well pump is not turning on: A malfunctioning pressure switch can also prevent the well pump from turning on. This may be caused by a switch that is stuck in the off position or a switch that is not sending the correct signal to the pump.
The well pump is not turning off: In some cases, a malfunctioning pressure switch may prevent the well pump from turning off, even when the pressure in the tank has reached the cut-out pressure.
Low water pressure: A malfunctioning pressure switch can cause low water pressure in the house. This is because the switch is not sending the correct signal to the well pump, which results in insufficient water being pumped into the pressure tank.
High electricity bills: If the well pump is turning on and off frequently due to a malfunctioning pressure switch, it can result in higher electricity bills. This is because the pump consumes a lot of energy when it turns on.

How to Reset Pressure Switch on Well Pump

Resetting the pressure switch on a well pump is a common task that can help to restore normal water pressure to your home. Once you have identified that the pressure switch is the root cause of the problem, you can proceed to reset it. Here’s a step-by-step guide on how to reset the pressure switch on well pump:

Step 1: Turn off the power supply to the well pump. You can do this by turning off the circuit breaker or unplugging the well pump.

Step 2: Locate the pressure switch. It is usually located near the pressure tank.

Step 3: Remove the cover of the pressure switch. The cover can be removed by loosening the screws that hold it in place.

Step 4: Locate the pressure switch lever. It is a small metal arm that is attached to the switch.

Step 5: Adjust the pressure switch lever. You can adjust the lever by turning the screw that is located on top of the switch. Turning the screw clockwise will increase the cut-in pressure while turning it counterclockwise will decrease the cut-in pressure.

Step 6: Set the cut-in and cut-out pressure. The cut-in pressure is the pressure at which the pump starts, while the cut-out pressure is the pressure at which the pump stops. The ideal cut-in and cut-out pressure for a well pump is usually between 20-40 psi. Consult your well pump manual for the recommended settings.

Step 7: Put the cover back on the pressure switch and tighten the screws.

Step 8: Turn on the power supply to the well pump.

Step 9: Monitor the well pump to make sure that it is working properly.

How to reset the pressure switch on well pump without the lever

Most pressure switches have a lever that can be used to manually reset the switch, but some models do not have this feature. In such cases, resetting the pressure switch may require a different approach. Here are the steps to follow if your pressure switch does not have a reset lever:

Turn off the power supply: As with any electrical work, it is important to turn off the power supply to the well pump before beginning any work on the pressure switch. You can do this by shutting off the circuit breaker or disconnecting the power cord.
Remove the cover: Use a screwdriver to remove the cover from the pressure switch. This will expose the electrical contacts and pressure adjustment screws.
Locate the contacts: Locate the two electrical contacts inside the pressure switch. These contacts are usually made of metal and will be visible once the cover is removed.
Disconnect the contacts: Use a pair of pliers to carefully disconnect the electrical contacts from the pressure switch. Be sure to grip the contact terminals and not the wires themselves to avoid damaging them.
Wait for a few minutes: After disconnecting the contacts, wait for a few minutes to allow any residual electrical charge to dissipate.
Reconnect the contacts: Use the pliers to reconnect the electrical contacts to the pressure switch. Make sure the contacts are securely in place.
Replace the cover: Carefully replace the cover on the pressure switch and secure it with the screws.
Turn on the power supply: Finally, turn on the power supply to the well pump and check that the water pressure has been restored to normal levels.

Safety Precautions Before Resetting Pressure Switch

Before resetting the pressure switch on your well pump, it is important to take certain safety precautions to prevent any accidents or injuries. Here are some safety tips to keep in mind:

Turn off the power supply: Before starting any work on your well pump, make sure to turn off the power supply to prevent electric shock. You can do this by shutting off the circuit breaker or disconnecting the power cord.

Release pressure from the system: Release any pressure from the water system by opening a faucet or the pressure relief valve on the pressure tank. This will prevent any water from spraying out when you remove the pressure switch cover.

Wear safety gear: When working on your well pump, it is important to wear safety gear such as gloves and safety goggles. This will protect your hands and eyes from any debris or sharp edges.
