Guide to Well Pump Pressure Switch Contacts Sticking Causes, Symptoms, and Fixing

If you rely on a well pump to supply water to your home, you are probably familiar with the well pump pressure switch. This essential component controls when the pump turns on and off based on water pressure levels. However, if the pressure switch contacts start to stick, it can lead to a range of problems, from low water pressure to noisy operation. In this article, we will discuss the causes, symptoms, and solutions of well pump pressure switch contacts sticking.

What is a well pump pressure switch?

Before we delve into the issue of sticking contacts, it is important to understand what a well-pump pressure switch is and how it works. Essentially, a pressure switch is a device that senses changes in water pressure and triggers the pump to turn on or off accordingly. There are two main types of pressure switches: the traditional electromechanical switch and the more modern solid-state switch. It is important to maintain your well pump pressure switch to ensure it functions correctly and reliably.

Causes of well pump pressure switch contacts sticking

Now that we know what a well pump pressure switch is and how it works, let’s look at the causes of contacts sticking. There are several reasons why pressure switch contacts can become stuck:

Electrical issues: If there is an electrical issue with the switch, such as loose connections or a damaged wire, it can cause the contacts to stick.
Mechanical issues: If there is a mechanical problem with the switch, such as a bent contact or a damaged spring, it can also cause sticking.
Environmental factors: The switch contacts can become dirty or corroded due to exposure to moisture or other environmental factors.
Age and wear: Over time, the switch contacts can wear out or become damaged due to normal use, leading to sticking.

Symptoms of well pump pressure switch contacts sticking

Now that we know the causes, let’s look at the symptoms of sticking contacts. Some of the most common symptoms include:

Low water pressure: If the contacts are stuck, the pump may not turn on when it should, resulting in low water pressure.

Frequent cycling: If the contacts are stuck, the pump may turn on and off frequently, which can cause premature wear and tear on the pump.

Noisy operation: If the contacts are sticking, the switch may vibrate or make a humming noise when the pump is running.

Inaccurate pressure readings: Sticking contacts can cause the pressure switch to reading inaccurate pressure levels, which can lead to improper pump operation.

Water hammer: Sticking contacts can also cause a water hammer, which is a loud banging noise that occurs when the pump turns on or off abruptly.

Solutions for well pump pressure switch contacts sticking

If you notice any of the above symptoms, it is important to address the issue as soon as possible to avoid further damage. Here are some solutions for well pump pressure switch contacts sticking:

Cleaning the contacts: In some cases, the contacts may simply be dirty or corroded. Cleaning them with fine-grit sandpaper or a contact cleaner can often resolve the issue.

Replacing the switch: If the contacts are too worn or damaged, replacing the switch may be necessary. It is important to replace the switch with one that is compatible with your pump and to follow manufacturer guidelines for installation.

Upgrading to a solid-state switch: Upgrading to a solid-state switch can often provide more reliable operation and eliminate sticking contacts.

Seeking professional help: If you are unsure of the cause of the problem or do not feel comfortable performing any repairs yourself, it is important to seek professional help from a qualified well-pump technician.

FAQs

Q: What is a well pump pressure switch?

A: A well pump pressure switch is a device that controls the water pressure in a well water system. It turns the pump on and off based on the pressure of the water in the system.

Q: What causes the contacts of a well pump pressure switch to stick?

A: The contacts of a well pump pressure switch can stick due to a variety of reasons, including debris or corrosion buildup, damage to the contacts, or a malfunctioning spring that controls the switch’s movement.

Q: How can I tell if the contacts of my well pump pressure switch are sticking?

A: One common sign of sticking contacts is inconsistent water pressure or a failure of the pump to turn on or off as expected. You may also hear a clicking or humming sound from the switch.

Q: How can I fix sticking contacts on my well pump pressure switch?

A: The first step in fixing sticking contacts is to turn off the power to the pump and remove the switch cover. You can then clean any debris or corrosion from the contacts using a wire brush or sandpaper. If the contacts are damaged or worn, they may need to be replaced. In some cases, it may be necessary to replace the entire pressure switch.

Q: Can I prevent the contacts on my well pump pressure switch from sticking?

A: Regular maintenance and cleaning can help prevent sticking contacts on your well pump pressure switch. Additionally, avoiding exposure to moisture or extreme temperatures and ensuring that the switch is properly installed can also help prolong its lifespan and prevent damage.

Q: Should I attempt to repair my well pump pressure switch myself?

A: If you have experience with electrical systems and feel confident in your ability to safely work on the switch, you may be able to repair it yourself. However, if you are unsure or uncomfortable working with electrical components, it is best to hire a professional to perform the repair.

Conclusion

In conclusion, well pump pressure switch contacts sticking can cause a range of problems for your well system. It is important to understand the causes and symptoms of sticking contacts and to address the issue as soon as possible to avoid further damage. Regular maintenance of your well pump pressure switch can also help prevent sticking contacts and ensure reliable operation. If you are experiencing any issues with your well pump pressure switch, don’t hesitate to seek professional help from a qualified technician.
