Well Pump Running But Not Building Pressure

Well Pump Running But Not Building Pressure: Troubleshooting Guide

Meta Description: Is your well pump running constantly but not producing water pressure? This comprehensive guide explores common causes, from simple fixes like air in the lines to more complex issues requiring professional help. Learn how to troubleshoot and resolve this frustrating problem.

A well pump that runs continuously without building pressure is a frustrating problem, leaving you without water when you need it most. This issue can stem from various sources, ranging from relatively simple fixes to more complex and potentially costly repairs. This troubleshooting guide will walk you through the most common causes and help you determine the best course of action.

Identifying the Problem: More Than Just a Low Pressure Situation

Before diving into solutions, it's crucial to understand the difference between low water pressure and a pump running without building any pressure. Low pressure might indicate a leaky faucet, a clogged aerator, or a minor issue within the well system. However, a pump running continuously without producing any pressure indicates a more significant problem requiring immediate attention. This article focuses specifically on the latter scenario.

Common Causes of a Running Well Pump with No Pressure:

Here's a breakdown of the most frequent culprits, from easiest to most complex:

1. Air in the Lines:

• Cause: Air trapped within the well pump system prevents water from flowing properly. This is a common occurrence after repairs, power outages, or periods of low water usage.
• Solution: Try bleeding the air from your plumbing system. Locate the pressure tank (usually a large cylindrical tank near your pump) and look for a bleed valve. Open this valve slowly to release trapped air. You may need to repeat this process several times. If you're unsure where the bleed valve is located, consult your well pump's manual or seek professional assistance.

2. Faulty Pressure Switch:

• Cause: The pressure switch controls the pump's on/off cycle based on water pressure. A malfunctioning switch might keep the pump running continuously, even with insufficient pressure.
• Solution: Inspect the pressure switch for any visible damage. If it appears damaged or corroded, replacement might be necessary. This usually involves turning off the power to the pump, carefully disconnecting the wires, and installing a new switch – a job best left to a qualified professional if you lack experience.

3. Issues with the Pressure Tank:

• Cause: A pressure tank stores water and helps maintain consistent pressure. A damaged bladder, leaking air valve, or insufficient air pressure within the tank can lead to constant pump operation.
• Solution: Check the air pressure within the tank. It should generally be about 2 psi less than the pump's cut-in pressure (check your pump's specifications). If the pressure is low, you may be able to add air using a tire inflator; however, a severely damaged bladder usually requires tank replacement.

4. Clogged or Damaged Well Screen or Pump:

• Cause: Sand, silt, or other debris can clog the well screen or the pump itself, restricting water flow. A damaged pump impeller might also be the culprit.
• Solution: This typically requires professional intervention. A well service technician can inspect the well screen and pump for obstructions or damage. They have the specialized equipment to clear blockages or replace damaged components.

5. Low Water Level in the Well:

• Cause: The water level in your well may have dropped significantly due to drought, overuse, or other factors. This prevents the pump from drawing enough water.
• Solution: Contact a well drilling or water well service company. They can assess your well's water level and explore possible solutions, such as deepening the well or implementing water conservation measures.

6. Electrical Problems:

• Cause: A faulty wiring connection, a tripped breaker, or a problem with the pump's motor can all lead to the pump running constantly without building pressure.
• Solution: Check your circuit breaker to ensure the well pump's circuit hasn't tripped. If the breaker keeps tripping, there might be a short circuit in the wiring. It's best to call a qualified electrician to troubleshoot and repair any electrical issues.

When to Call a Professional:

While some simple troubleshooting steps can be performed independently, certain issues require the expertise of a qualified well pump technician. Don't hesitate to call a professional if:

• You're uncomfortable working with electrical components or plumbing systems.
• You've tried basic troubleshooting and the problem persists.
• You suspect issues with the well screen, pump, or pressure tank.
• You're dealing with a significant drop in water level.

Addressing a well pump that runs without building pressure promptly is crucial to avoid further damage and ensure a reliable water supply. By following this guide and knowing when to seek professional help, you can get your well pump back up and running efficiently.
