Tips For Troubleshooting Issues With Your Submersible Well Pump

When you own a home with a well, recognizing well pump problems is important. When you can recognize and troubleshoot problems with your submersible well pump, you'll be in a better position to restore your water flow as quickly as possible. Here are a few common issues you might experience and some troubleshooting tips for resolution.

Pump Motor Isn't Starting

If the pump motor isn't starting, the first thing to check is the power supply. Check the circuit breaker to be sure that the breaker isn't tripped. Reset it by flipping the breaker switch off then back on. If this doesn't fix the problem, there may be a blown fuse. Try replacing the fuse to see if that restores power. While you're checking the fuse and circuit breaker, you should also check the wiring. If any of the wiring is worn, frayed or broken, that can hinder the motor operation.

Another common problem with well pumps is sand binding. If the pump has drawn sand in, that can bind the motor. You'll have to have a technician pull the pump and flush it to fix this. If all else fails, your well pump technician should also check the pressure switch and control box before replacing the motor entirely.

Pump Motor Starts Too Frequently

If the pump motor is coming on too often, you're risking burning it out. One common cause for the motor to come on too often is a stuck valve. If the pressure valve is stuck open, it won't hold proper pressure in the motor, causing it to continually engage. The same can happen if the pressure switch is faulty. Try resetting the pressure switch limit. You should also have the entire system checked by a technician to identify any potential leaks. Leaks in the lines can affect the pressure in the system, which may cause the motor to run more often than it needs to.

Pump Motor Doesn't Shut Off

If the pump motor is running non-stop, that's a sure sign that the pressure switch is failing or needs to be adjusted. Try cleaning the contacts, adjusting the setting on the switch or replacing it altogether.

A non-stop motor can also be caused by low water levels in the well. If the pump is exceeding the refill capacity of the well, that can cause the well to run dry. Shut the pump off at the breaker and let the well refill for a while. If necessary, pull the pump and throttle the output a bit to slow the water draw. Just don't put the pump back in until there's enough water to avoid any sand draw.

A non-stop motor can also be caused by leaks in the pump system as well as an old or worn out pump. Your well pump technician can check both of these things. While inspecting the system, he or she will also check the motor shaft for damage or any wear in the coupling.

With these tips and the help of a reliable well pump technician, you can keep your well flowing at its best. Contact a business, such as Modern Pump & Equipment, for more information.
