Well Not Building Pressure? 7 Fixes You Need to Know!

Hydraulic systems, crucial components in industries ranging from construction to manufacturing, rely on consistent pressure for optimal performance. When the American Society of Mechanical Engineers (ASME) guidelines aren’t followed, or if you’re experiencing issues with components sourced from manufacturers like Parker Hannifin, you might encounter the challenge of well not building pressure. Addressing the problem of well not building pressure requires a systematic approach, ensuring the longevity and efficiency of your machinery through proper maintenance and troubleshooting techniques.

Well Not Building Pressure? 7 Fixes You Need to Know!

This article aims to help you troubleshoot why your well isn’t building pressure. Low water pressure can be frustrating, but often the cause is something you can fix yourself. We’ll explore several common reasons and provide actionable steps to restore your water pressure.

Understanding How Your Well System Works

Before diving into the fixes, it’s crucial to understand the basic components of your well system and how they work together to deliver water to your home.

• The Well: This is your water source. Water is drawn from an underground aquifer.
• Submersible Pump (or Jet Pump): This pump, located either in the well (submersible) or above ground (jet), draws water from the well.
• Pressure Tank: This tank stores water under pressure, allowing the pump to cycle less frequently.
• Pressure Switch: This device monitors the water pressure in the tank and signals the pump to turn on or off to maintain a specific pressure range (e.g., 40-60 PSI).
• Water Lines: Pipes that transport water from the well, through the tank, and into your home.

Common Reasons for Low Well Pressure and Their Solutions

Here are seven common reasons why your well might not be building pressure, along with actionable fixes:

1. Low Water Level in the Well

   This is a fundamental problem. If the water level in your well is too low, the pump won’t be able to draw enough water to build pressure.

   • Symptoms: Pump runs continuously but delivers little or no water; sputtering faucets.

   • Fixes:

     • Check Well Depth: Consult your well log or have a professional measure the water level.
     • Lower the Pump (if possible): If the water level has dropped significantly, you might be able to lower the submersible pump. This is a job best left to professionals.
     • Consider Drilling Deeper or a New Well: If the aquifer is depleted, you might need to consider more drastic measures.
     • Conserve Water: Implement water-saving practices to allow the well to recharge.

2. Faulty Pressure Switch

   The pressure switch is responsible for turning the pump on and off. If it’s malfunctioning, it might not be signalling the pump correctly.

   • Symptoms: Pump doesn’t turn on at all, runs constantly, or cycles rapidly.

   • Fixes:

     • Inspect the Pressure Switch: Look for signs of corrosion, damage, or debris.
     • Clean the Switch: Sometimes, debris can clog the pressure switch. Carefully clean it with a small brush or wire.
     • Adjust the Pressure Settings (If Possible): Some pressure switches have adjustable settings. Refer to your switch’s documentation for instructions.
     • Replace the Pressure Switch: If cleaning and adjusting don’t work, replace the pressure switch. These are relatively inexpensive and easy to replace.

3. A Bladder Tank Issue

   The bladder inside the pressure tank maintains air pressure, which is crucial for storing water under pressure. If the bladder is damaged or has lost air, it won’t function properly.

   • Symptoms: Waterlogged tank (heavy when tapped), short cycling (pump turns on and off frequently), fluctuating water pressure.

   • Fixes:

     • Check the Air Charge: Use a tire pressure gauge to check the air pressure in the tank. It should typically be 2 PSI below the pump’s cut-in pressure (e.g., 38 PSI for a 40-60 PSI system).
     • Add Air to the Tank: If the pressure is low, use an air compressor to add air.
     • Replace the Tank: If the bladder is damaged, the entire tank will need to be replaced.

4. Clogged Well Screen or Pump Intake

   Over time, sediment and debris can accumulate around the well screen or the pump intake, restricting water flow.

   • Symptoms: Reduced water flow, pump straining, cloudy or discolored water.

   • Fixes:

     • Shock Chlorinate the Well: This can help break down some organic matter.
     • Professionally Clean the Well: A well service company can use specialized equipment to clean the well and pump intake.

5. A Leak in the System

   Even a small leak can significantly reduce water pressure.

   • Symptoms: Low water pressure, wet spots around pipes or fittings, pump running more frequently than usual.

   • Fixes:

     • Inspect All Plumbing: Carefully check all pipes, fittings, and connections for leaks. Pay particular attention to areas near the well, pressure tank, and pump.
     • Repair or Replace Leaky Components: Replace any damaged pipes or fittings.

6. A Failing Well Pump

   Pumps have a limited lifespan. Over time, they can wear down and lose efficiency.

   • Symptoms: Low water pressure, pump running constantly but delivering little water, unusual noises from the pump.

   • Fixes:

     • Test the Pump’s Electrical Circuit: Ensure the pump is receiving adequate power.
     • Replace the Pump: If the pump is old or showing signs of failure, replacing it is often the best solution.

7. Sediment or Debris in Plumbing

   Accumulated sediment can block pipes and fixtures, reducing water flow and pressure.

   • Symptoms: Low water pressure, especially at specific faucets or fixtures; sputtering water.

   • Fixes:

     • Flush the Plumbing System: Open all faucets and run them for a few minutes to flush out any sediment.
     • Clean Aerators and Showerheads: Remove and clean aerators on faucets and showerheads, as these are common places for sediment to accumulate.
     • Install a Whole-House Filter: A whole-house filter can help prevent sediment from entering your plumbing system.
