Why Is My Well Pump Running Constantly?
Common Causes, Troubleshooting Tips, and When You Need Well Pump Repair
If you are wondering why your well pump is running constantly, your well system may have a problem that needs attention. A properly working well pump should turn on when water pressure drops and shut off once the pressure tank reaches the correct level.
A well pump running constantly can waste electricity, put unnecessary stress on your equipment, and eventually lead to a complete system failure. In many cases, the issue is caused by something simple like a plumbing leak or pressure switch problem. Other times, it may require professional well pump repair.
At H&M Water Solutions, we help homeowners diagnose and repair well system problems throughout Western Montana. Understanding the possible causes can help you know what to check and when it is time to call for help.
How a Well Pump System Works
A private well system uses several components that work together to provide water to your home.
These include:
- Well pump
- Pressure tank
- Pressure switch
- Electrical controls
- Water lines
When you use water in your home, pressure inside the tank drops. Once it reaches the cut-in pressure, the pressure switch turns the pump on. The pump then fills the pressure tank until the system reaches the correct pressure and shuts off.
When a pump keeps running without stopping, it usually means the system cannot build enough pressure to tell the pump to turn off.
Signs Your Well Pump Is Running Constantly
Many homeowners first notice a problem when they hear the pump running longer than normal.
Common warning signs include:
- The pump never seems to shut off
- Low water pressure throughout your home
- Fluctuating water pressure
- Higher electric bills
- The pump becoming hot
- The pressure gauge not reaching normal levels
- Water pressure dropping when multiple fixtures are used
If you notice these issues, it is a good idea to investigate before the pump wears out.
Common Reasons Your Well Pump Keeps Running
1. A Plumbing Leak
A leaking pipe is one of the most common reasons a well pump keeps running.
Your well pump turns on when pressure drops. If water is constantly escaping somewhere in your plumbing system, the pressure never reaches the shut-off point.
Possible leaks include:
- Broken underground water lines
- Leaking faucets
- Running toilets
- Outdoor spigots
- Irrigation leaks
Even a small leak can cause your pump to run far longer than normal.
To check for leaks:
- Turn off all faucets and water appliances.
- Watch your pressure gauge.
- Listen for water running when nothing is being used.
If pressure continues dropping, there may be a leak somewhere in the system.
2. Pressure Tank Problems
Your pressure tank stores water and helps prevent your pump from turning on every time someone uses water.
A failing pressure tank can cause:
- Frequent cycling
- Poor water pressure
- Longer pump run times
- A pump that will not shut off
Common pressure tank issues include:
- Failed bladder
- Incorrect air pressure
- Waterlogged tank
- Internal damage
A damaged pressure tank is a common reason homeowners need professional well system service.
3. Faulty Pressure Switch
The pressure switch controls when your pump turns on and off.
If the switch becomes damaged, dirty, or stuck, it may not signal the pump to shut off.
Signs of a bad pressure switch include:
- Pump running continuously
- Clicking sounds
- Inconsistent pressure
- Burned electrical contacts
Because pressure switches involve electrical connections, repairs should be handled carefully.
4. Low Water Pressure Well Problems
A low water pressure well issue can happen for several reasons.
Some common causes include:
- A failing well pump
- A clogged filter
- A failing pressure tank
- A restricted water line
- A low-producing well
If your well cannot supply enough water to keep up with demand, the pump may continue running while trying to maintain pressure.
Signs of low water pressure include:
- Weak shower pressure
- Faucets slowing down
- Pressure dropping when appliances run
- Air or sputtering from faucets
If your home has ongoing low water pressure, professional testing can help identify the cause.
5. A Worn-Out Well Pump
Like any mechanical equipment, well pumps eventually wear out.
Over time, pump components can lose efficiency and prevent the system from reaching the correct pressure.
A failing pump may cause:
- Constant operation
- Low water pressure
- Reduced water flow
- No water at all
Most well pumps last many years, but their lifespan depends on water quality, usage, installation, and maintenance.
When a pump can no longer build pressure, well pump repair or replacement may be needed.
6. A Clogged Water Filter
A clogged sediment filter can restrict water flow and make your pump work harder.
Before assuming you need major repairs, check when your filter was last replaced.
A simple filter replacement may solve the issue and help your system operate normally again.
7. Check Valve Failure
The check valve prevents water from flowing back into the well after the pump shuts off.
If the valve fails:
- Water can drain back into the well
- Pressure drops
- The pump continues running
This problem often requires professional diagnosis because the valve may be located inside the well system.
Can a Well Pump Running Constantly Damage the System?
Yes. A pump that runs continuously can shorten the life of your equipment.
Potential problems include:
- Overheated pump motor
- Increased electric costs
- Damaged pressure switch
- Premature pump failure
- Complete loss of water service
Addressing the issue early can help prevent a much larger repair.
What Should You Do If Your Well Pump Won't Shut Off?
Before calling for service, you can check a few things:
Check for leaks
Look for dripping faucets, running toilets, or wet areas around your property.
Check your pressure gauge
If the pressure never reaches the shut-off point, the system may have a mechanical issue.
Check your filter
A clogged filter is a simple problem that can affect system performance.
Avoid letting the pump run for hours
If your pump has been running continuously, shutting it off temporarily may help prevent damage until the issue can be diagnosed.
Can I Fix a Well Pump That Runs Constantly Myself?
Some causes of a constantly running well pump are simple issues homeowners can check on their own. Before calling for service, you may be able to identify obvious problems and rule out a few common causes.
You can check for:
- Clogged water filters that may be restricting flow
- Plumbing leaks from faucets, toilets, outdoor spigots, or water lines
- Pressure readings on your pressure gauge
- Visible signs of damage around your well equipment
However, many well pump problems require specialized tools and experience to diagnose correctly.
Professional well pump repair may be needed for issues involving:
- Pressure switch replacement
- Well pump replacement
- Electrical testing
- Pulling and inspecting a submersible pump
- Well system diagnostics
- Pressure tank replacement
Well systems combine electricity, pressurized water lines, and equipment that is often located underground. Attempting repairs without the proper knowledge can lead to equipment damage, electrical hazards, or a larger repair.
If your well pump is running constantly and basic checks do not identify the problem, H&M Water Solutions can inspect your system and determine the right solution.

Frequently Asked Questions
Why is my well pump running constantly?
A well pump may run constantly because the system cannot build enough pressure to reach the shut-off point. Common causes include a plumbing leak, failing pressure tank, faulty pressure switch, clogged filter, low water supply, damaged check valve, or a worn-out pump.
If your well pump is running constantly, it is important to identify the cause quickly. A pump that continues running without stopping can increase energy costs and put unnecessary strain on the motor and other components.
Can a bad pressure tank cause a well pump to run constantly?
Yes. A failing pressure tank can prevent your well system from maintaining proper pressure, causing the pump to run longer than normal or never shut off.
Pressure tanks help regulate water pressure and reduce how often your pump needs to start. If the tank becomes waterlogged, loses its air charge, or the internal bladder fails, your system may struggle to operate correctly.
Can low water pressure mean my well pump is failing?
Yes. Low water pressure can be a sign that your well pump is struggling to keep up with your home's water demand. A worn-out pump may still run, but it may not be able to move enough water or build enough pressure for your system to operate properly.
Low water pressure can also be caused by a failing pressure tank, clogged filter, plumbing leak, faulty pressure switch, or a low-producing well. If your home has weak water pressure, fluctuating pressure, or a noticeable drop in flow, your well system may need professional troubleshooting.
How long should a well pump run before shutting off?
A normal well pump cycle depends on your system size, pressure tank capacity, and water usage. In most homes, the pump should run for a few minutes and then shut off once the pressure tank reaches the correct level.
A pump that runs continuously for an extended period is a sign that something is preventing the system from reaching its shut-off pressure.
Should I turn off my well pump if it will not stop running?
If your well pump has been running continuously for hours, turning off the power may help prevent additional damage. A pump that runs nonstop can overheat the motor and shorten the life of the equipment.
After shutting off the pump, check for obvious leaks and contact a professional for diagnosis. H&M Water Solutions can inspect your system and determine if you need well pump repair or another type of service.
Can a leaking pipe cause my well pump to keep running?
Yes. A leaking pipe can cause your well system to continuously lose pressure, which signals the pump to keep running. Underground water lines, outdoor faucets, toilets, and irrigation systems are common sources of leaks.
Finding and repairing the leak can often restore normal pump operation.
Is it expensive to repair a well pump that keeps running?
The cost depends on what is causing the problem. Simple issues like a clogged filter, pressure switch adjustment, or minor leak may require a smaller repair. More serious problems involving the pump motor, electrical components, or underground lines may require more extensive service.
Having the system inspected early can help prevent a complete pump failure and a more expensive replacement.
