Low Well Water Pressure & How to Fix It

Are you struggling with low well water pressure? If you rely on a well for your home’s water supply, you expect consistent water pressure for showers, faucets, appliances, and outdoor use. So when the pressure suddenly drops or is consistently low, it’s more than just an inconvenience—it can signal an issue that needs fixing. 

If you’re asking, “Why do I have low well water pressure?” here are the most common reasons, what they mean, and how you can fix them.

1. Clogged Pipes or Fixtures Can Attribute to Low Well Water Pressure 

Mineral buildup in pipes and fixtures is one of the most common causes of low water pressure in homes with well water. Over time, minerals like calcium and iron can collect inside pipes, narrowing the space water can flow through.

Signs to look for:

• Pressure is low at one or two specific fixtures.
• You see rust or mineral deposits on faucets or showerheads.
  

Solution: Clean or replace the affected fixtures. If the buildup is extensive, an experienced plumber may need to flush or replace parts of your plumbing system. Installing a water softener can help prevent future buildup.

2. Water Pressure Tank Issues

Your well system includes a pressure tank that regulates water pressure throughout your home. If the tank isn’t functioning properly, you’ll notice drops in water pressure.

Possible causes:

• The well pump pressure switch is set too low or is malfunctioning.
• The tank’s air charge is off balance.
• There’s waterlogging (too much water, not enough air in the tank).
  

Solution: Check the pressure switch and adjust it if needed (common settings are 40/60 psi or 30/50 psi). If you’re not sure, call a professional to inspect the tank and make the necessary adjustments.

3. Pump Problems Causing Low Well Water Pressure 

Your well pump is responsible for moving water from the well into your home. If it’s failing or undersized, your water pressure will suffer.

Common problems:

• The pump is wearing out and can’t keep up with demand.
• It’s too small for your household’s water usage.
• The pump is set too shallow and can’t draw enough water.

Solution: A professional can inspect the pump, check the flow rate, and recommend repair or replacement if needed. For larger households or high water usage, a constant pressure system may be worth considering.

4. Well Water Pressure Switch Settings

The pressure switch controls when your pump turns on and off based on tank pressure. If the settings are too low, your water pressure will also be low.

How it works:

• The switch typically has a cut-in and cut-out setting (e.g., 30/50 or 40/60 psi).
• If the switch is dirty, worn out, or set incorrectly, pressure will be inconsistent.
  

Solution: You can adjust the switch settings to increase pressure, but only if your pump and tank can handle it. A licensed well-specialist can safely make these adjustments.

5. Water Filter or Softener Clogs

Many homes with well water use filters or softeners to improve water quality. But if these systems are clogged, they can choke water flow and lower pressure.

Warning signs:

• Water pressure drops suddenly.
• Filters haven’t been changed recently.
• Water softener regeneration seems off-schedule.

Solution: Replace clogged filters and maintain your softener regularly. Check the user manual for recommended maintenance intervals.

6. Leaks in the Plumbing System Can Cause Low Well Water Pressure

Leaks in your water lines can lead to noticeable drops in pressure, especially if the leak is large or continuous.

What to watch for:

• Unexplained damp spots around the house or yard.
• High energy or water bills.
• Constantly running well pump.
  

Solution: If you suspect a leak, turn off all water and listen for the sound of running water or check the pump. A well-specialist can use specialized tools to find and fix hidden leaks.

7. Peak Demand Times

Sometimes, the problem isn’t your well system—it’s the demand. If multiple appliances and fixtures are running at the same time, you may experience a temporary drop in pressure.

Common culprits:

• Washing machine, dishwasher, and showers running at once.
• Outdoor irrigation systems

Solution: Stagger water use when possible. For larger households, upgrading to a constant pressure system can help maintain stable pressure regardless of demand.
