A submersible well pump is a crucial component in many water supply systems, especially in rural areas where access to municipal water might be limited. As a supplier of Submersible Well Pump, I've encountered numerous situations where customers face issues with their pumps not working. In this blog, I'll share some practical steps to troubleshoot a submersible well pump that has stopped functioning.
Check the Power Supply
The first and simplest step in troubleshooting is to check the power supply. A lot of times, the problem can be as basic as a tripped circuit breaker or a blown fuse. Head over to your electrical panel and look for any breakers that have been switched to the "off" position. If you find one, switch it back on. If it trips again immediately, there might be a more serious electrical issue with the pump.
Similarly, check for blown fuses. In some older electrical systems, fuses are used instead of circuit breakers. A blown fuse will have a broken filament inside. Replace it with a new fuse of the same amperage rating.
It's also a good idea to check the power cord of the pump. Look for any visible signs of damage, such as cuts or frayed wires. If you find any, the power cord will need to be repaired or replaced. Sometimes, the power cord might have come loose from the electrical connection. Make sure it is securely plugged in.
Inspect the Pressure Switch
The pressure switch is an important part of the well pump system. It controls when the pump turns on and off based on the water pressure in the system. A faulty pressure switch can cause the pump to stop working.
First, check the pressure switch settings. Most pressure switches have two settings: the cut - in pressure (the pressure at which the pump turns on) and the cut - out pressure (the pressure at which the pump turns off). These settings are usually adjustable. Make sure they are set correctly according to the manufacturer's specifications.
Next, look for any signs of damage or wear on the pressure switch. Check the electrical connections to make sure they are tight and free of corrosion. If you suspect the pressure switch is faulty, you can test it using a multimeter. A bad pressure switch will need to be replaced.
Examine the Well and Water Level
The well itself can be a source of problems for the submersible well pump. If the water level in the well has dropped too low, the pump might be running dry. This can cause the pump to overheat and eventually stop working.
You can check the water level in the well using a well water level meter. If the water level is below the pump intake, you might need to wait for the water level to rise or consider installing a deeper well or a pump with a lower intake.
Another issue could be debris or sediment in the well. Over time, dirt, sand, and other particles can accumulate in the well and clog the pump intake. This can reduce the flow of water to the pump and cause it to malfunction. You can try flushing the well to remove any debris. If the problem persists, you might need to hire a professional well driller to clean the well.
Check the Pump Impeller and Motor
The impeller is a key component of the submersible well pump. It is responsible for drawing water into the pump and pushing it through the system. If the impeller is damaged or clogged, the pump will not be able to function properly.
To check the impeller, you will need to remove the pump from the well. This is a job that should be done carefully, following all safety procedures. Once the pump is out, inspect the impeller for any signs of damage, such as cracks or chips. You can also check for any debris that might be stuck in the impeller. If you find any debris, clean it out carefully. If the impeller is damaged, it will need to be replaced.
The motor is the heart of the pump. If the motor is not working, the pump will not run. Check the motor for any signs of overheating, such as a burning smell or a hot surface. Overheating can be caused by a variety of factors, including a clogged impeller, low water level, or an electrical problem. If the motor is overheating, you need to identify and fix the underlying cause.
You can also test the motor using a multimeter to check for continuity. If there is no continuity, it indicates that the motor has a problem and might need to be replaced.
Look for Leaks in the System
Leaks in the water supply system can cause the pump to work harder and eventually fail. Check all the pipes, fittings, and connections in the system for any signs of leaks. Look for water stains, drips, or puddles around the pipes.
If you find a leak, you can try to repair it using pipe sealant or by replacing the faulty fitting. In some cases, a more extensive repair might be required. Make sure to address all leaks promptly to prevent further damage to the pump and the system.
Consider the Age and Condition of the Pump
Submersible well pumps have a limited lifespan. If your pump is old and has been in use for a long time, it might simply be reaching the end of its useful life. Over time, the components of the pump can wear out, leading to reduced performance and eventual failure.
If you have an older pump that has been experiencing multiple problems, it might be more cost - effective to replace it with a new one.
