Why Your Well Pressure Switch Won’t Turn Off and What to Do About It

Any system that uses a water well needs a well pressure switch. By switching the water pump on and off as necessary, it keeps the system’s pressure constant. Unfortunately, there may be instances where the pressure switch does not shut off, resulting in a number of problems. In this post, we’ll look at the reasons why a well pressure switch won’t turn off, warning indications to look out for, and solutions.

Causes of a well pressure switch not turning off

Pressure Switch

There are numerous and diverse factors that could prevent a well pressure switch from turning off. Among these, a defective pressure switch is a major offender that can cause a variety of problems, such as:

Faulty pressure switch

If the contacts within the switch get stuck or jammed, the pump may still run and cause an unremitting increase in pressure.

Malfunctioning pressure tank

A broken pressure tank is another possible source of issues since it might keep the pump from stopping the pressure switch by causing it to operate continuously. Also, if the pressure tank leaks or becomes soggy, it may be unable to maintain the necessary air pressure, rendering the switch useless.

Clogged Water Filters

Water filters that are clogged can also prove to be a severe problem since they can prevent water from flowing freely, which forces the pressure switch to keep operating in order to keep the system’s pressure at a certain level. It is crucial to maintain the filters by replacing them on a regular basis in order to avoid this problem.

3 Signs of a Well Pressure Switch Not Turning Off

If you observe any of the following indications, it may suggest that your well pressure switch is not turning off:

  1. Water Hammer: A noisy banging sound, referred to as a water hammer, may ensue when the water flow is swiftly halted. This auditory clue serves as an indicator that the pressure switch is not turning off, which can result in this peculiar noise.
  2. Reduced Water Pressure: When the pressure switch fails to turn off, the water pressure within the system may be adversely affected, resulting in diminished water output from your faucets and showers.
  3. Cycling On and Off: If your well pump is frequently activating and deactivating, it is a telltale sign that the pressure switch is not turning off, causing it to repeatedly cycle on and off.

How to Fix a Well Pressure Switch Not Turning Off

In the event that you happen to be encountering any of the aforementioned symptoms, it is of paramount importance to promptly remedy the situation in order to circumvent any adverse effects on your health system. To this end, we shall now elucidate the course of action necessary to rectify a malfunctioning well pressure switch that refuses to deactivate:

Step 1: Commence by deactivating the power supply to the well pump.

Step 2: Proceed to expunge the entire system of any superfluous water by initiating the opening of the drain valve, thereby facilitating the smooth drainage of the water.

Step 3: Next, carefully remove the cover of the pressure switch and meticulously scrutinize the contacts. Should the contacts appear to be worn out or corroded, it is incumbent upon you to substitute the pressure switch.

Step 4: Following the successful installation of the new pressure switch, reattach the cover to the pressure switch.

Step 5: At this juncture, switch the power supply back on and proceed to perform a comprehensive system test to ensure that the pressure switch has indeed been successfully deactivated.

Tips on Maintaining the Pressure Switch

Maintaining a good pressure switch is essential to ensuring that it functions properly. Adhering to several rules that aim to improve the system’s longevity and prevent it from failing to turn off might reduce the complexity of this process. Some things to keep in mind are listed below.

To begin, the air pressure in the pressure tank must be checked and adjusted on a regular basis to ensure proper operation. By adhering to this procedure, potential problems can be avoided and the switch’s longevity increased.

Important maintenance tasks include replacing water filters as directed by the manufacturer. The goal of this procedure is to keep the filters from becoming clogged and slowing down the system.

In addition, it is crucial to inspect the pressure switch contacts on a regular basis to detect any signs of wear or corrosion. To keep the system running well, a faulty switch must be immediately replaced upon detection. By adhering to these procedures, you may extend the life of your well pressure switch and guarantee its perfect operation.


The failure of a well pressure valve to turn off can result in a number of issues with your well system, including decreased water pressure and intermittent operation. By comprehending the issue’s causes and symptoms, it is possible to diagnose and resolve the issue. In addition to preventing the issue from arising in the first place, routine maintenance can help prevent its occurrence. In order to avoid damaging your well system, it is best to seek professional assistance if you are unsure of how to resolve the issue. By adhering to these guidelines, you can ensure that your well system operates effortlessly and effectively.
