Why Your Well Pump Is Losing Prime

A well pump is an essential part of any household that relies on a well for water supply. However, well pumps can lose prime, leading to reduced water pressure and potentially costly repairs. In this article, we’ll explore the reasons behind prime loss in well pumps and provide expert tips on how to restore it.

Understanding how well pumps work is crucial in identifying the causes of prime loss and taking corrective action. A well pump uses a submersible or jet pump to draw water from the well and pressurize it for household use.

How Well Pumps Work

When a well pump is in operation, the pump creates suction and draws water from the well. The water is then pressurized and distributed throughout the household. The well pump relies on a priming mechanism to maintain a vacuum seal and prevent air from entering the system.

The priming mechanism typically consists of a priming valve, a fill tube, and a check valve. When the pump is turned off, the fill tube allows air to enter the system and the check valve prevents water from flowing back into the well.

Causes of Prime Loss

Prime loss in well pumps can occur due to various reasons, including:

• Air entering the system through cracks or gaps in the well casing or pipe
• Clogged or restricted pipes or fittings
• Worn or damaged priming valve or fill tube
• Incorrect pump installation or maintenance
• Electrical issues or malfunctioning pump controls

It’s essential to identify the root cause of prime loss to take corrective action and prevent future occurrences.

Restoring Prime

Restoring prime in a well pump involves addressing the underlying cause of prime loss and making necessary repairs or adjustments. In some cases, it may be necessary to replace the entire pump or reconfigure the plumbing system.

If air has entered the system, it’s essential to bleed the air from the pipes and recharge the system with water. This can be done by turning off the pump and opening the fill valve until water flows from the pipe.

Regular maintenance of the well pump, including inspecting and replacing worn parts, can help prevent prime loss and extend the lifespan of the pump.

Conclusion

Prime loss in well pumps can be frustrating and costly if left unchecked. By understanding the causes of prime loss and taking corrective action, homeowners can restore prime and ensure reliable water supply.

Frequently Asked Questions

What causes air to enter the well pump system?

Air can enter the system through cracks or gaps in the well casing or pipe, clogged or restricted pipes or fittings, or worn or damaged priming valve or fill tube.

How do I bleed air from the well pump system?

To bleed air from the system, turn off the pump and open the fill valve until water flows from the pipe. This allows air to escape and water to re-enter the system.

Can I restore prime in a well pump myself?

While some minor repairs can be done by the homeowner, it’s often best to consult a professional well driller or plumber to ensure safe and effective restoration of prime.

What are the consequences of neglecting prime loss in a well pump?

Neglecting prime loss can lead to reduced water pressure, increased energy consumption, and potentially costly repairs or even replacement of the pump.

How often should I inspect and maintain my well pump?

Regular maintenance of the well pump, including inspecting and replacing worn parts, can help prevent prime loss and extend the lifespan of the pump.
