If your well pump is cycling but no water is running, it can be a frustrating and costly problem for homeowners who rely on their well for water. The constant on-and-off cycling of the pump can wear out its components quickly and lead to unnecessary energy consumption.
In this article, we will explore the causes of well pump cycling with no water running and provide solutions to help you avoid this issue.

What is Well Pump Cycling?
Well pump cycling occurs when a well pump turns on and off repeatedly, even when no water is being used. This happens because the pressure in the well tank drops below the pump’s set point. When the pressure drops, the pump turns on to bring the pressure back up to the set point. Once the set point is reached, the pump turns off until the pressure drops again, and the cycle repeats.
While some cycling is normal, excessive cycling can cause the pump to wear out more quickly, consume more energy, and eventually fail. It can also be a sign of a deeper problem that requires attention.
Causes of Well Pump Cycling But No Water Running
There are several reasons why a well pump may cycle with no water running:
Leaking Faucets or Toilets
A leaking faucet or toilet can cause a significant amount of water to be wasted, even if it seems like only a small amount. This constant flow of water can cause the pressure in the well tank to drop, leading to the pump turning on and off repeatedly.
To check for leaking faucets or toilets, turn off all the water in the house, including outdoor spigots. Then, go to the well tank and listen for any water running. If you hear water running, there is likely a leak somewhere that needs to be fixed.
Faulty Pressure Switch
The pressure switch is the component of the well pump that tells it when to turn on and off. If the pressure switch is faulty, it may not be able to accurately detect the pressure in the well tank, causing the pump to turn on and off frequently.
To check the pressure switch, turn off the power to the pump and remove the cover from the pressure switch. Then, use a multimeter to test the switch’s contacts to see if they are functioning properly. If they are not, the switch will need to be replaced.
Waterlogged Pressure Tank
The pressure tank is a critical component of the well system that helps regulate the pressure and reduce the number of times the pump has to turn on and off. If the pressure tank becomes waterlogged, it can no longer hold the air that helps regulate the pressure, causing the pump to turn on and off more frequently.
To check if the pressure tank is waterlogged, turn off the power to the pump and drain all the water from the tank. Then, use a tire pressure gauge to check the air pressure inside the tank. If the pressure is too low, add more air until it reaches the manufacturer’s recommended pressure.
Clogged Well Screen or Pipes
A clogged well screen or pipes can reduce the flow of water to the pump, causing the pressure in the well tank to drop and the pump to turn on and off repeatedly.
To check for clogs, turn off the power to the pump and remove the well cap. Then, use a flashlight to inspect the well screen and pipes for any debris or buildup. If you find any clogs, use a brush or other tool to remove them.
Faulty Check Valve
The check valve is a one-way valve that keeps water from flowing back down the well when the pump is off. If the check valve is faulty, water can flow back down the well, causing the pressure in the well tank to drop and the pump to turn on and off frequently.
To check the check valve, turn off the power to the pump and disconnect the pipe leading from the well to the pressure tank. Then, use a flashlight to inspect the check valve for any signs of damage or wear. If the check valve is faulty, it will need to be replaced.
Solutions for Well Pump Cycling with No Water Running
If you’re experiencing well pump cycling with no water running, there are several solutions you can try:
Fix Leaking Faucets or Toilets
If you have leaking faucets or toilets, fixing them will help reduce the amount of water wasted and prevent the well pump from cycling unnecessarily. Learn to fix leaking faucets.
Replace Faulty Pressure Switch
If the pressure switch is faulty, replacing it with a new one will help ensure that the pump turns on and off at the correct pressure levels.
Recharge the Pressure Tank
If the pressure tank is waterlogged, recharging it with air will help regulate the pressure and reduce the number of times the pump has to turn on and off.
Clean Clogged Well Screen or Pipes
If the well screen or pipes are clogged, cleaning them will help restore the flow of water to the pump and reduce cycling.
Replace Faulty Check Valve
If the check valve is faulty, replacing it will help ensure that water doesn’t flow back down the well and cause the pump to cycle unnecessarily.
Preventing Well Pump Cycling with No Water Running
To prevent well pump cycling with no water running from happening in the future, there are a few steps you can take:
Conduct Regular Maintenance
Regular maintenance of your well system can help prevent issues from occurring. This includes checking the pressure tank’s air pressure, inspecting the well screen and pipes for clogs, and testing the pressure switch.
Install a Low-Flow Toilet
Replacing an old, inefficient toilet with a low-flow model can help reduce the amount of water used in your home and prevent the well pump from cycling unnecessarily.
Install a Water Softener
If your well water is hard, installing a water softener can help prevent mineral buildup in your pipes and well screen, reducing the risk of clogs and well pump cycling.
Install a Pressure Regulator
Installing a pressure regulator can help regulate the water pressure in your home, reducing the risk of pressure drops that can cause the well pump to cycle unnecessarily.
Some Additional Tips
Additionally, it’s essential to note that well pump cycling with no water running can also be a sign of more severe issues with your well system, such as a well running dry or a failing well pump. If you’ve tried the above solutions and are still experiencing cycling, it’s essential to call a professional well contractor to inspect your system thoroughly.
A professional well contractor will be able to identify any underlying issues with your well system and provide solutions to fix them. They may recommend a well yield test to determine if your well is producing enough water for your household’s needs, or they may suggest replacing your well pump if it’s failing.
