Most residential well owners prefer a submersible well pump over jet types because of their longevity. However, even with their long life spans, a submersible well pump can have problems here and there. As the owner of a private well that is harvested by a submersible well pump, it is best to get to know the symptoms that there is something wrong and understand the potential causes. Because the submersible well pump is situated inside the well, it can make it difficult to pinpoint issues if you are unfamiliar with the signs. Here are a few of the most common problems with submersible well pumps and the causes and solutions you should know.
Problem: The pump is starting up and running more often than usual.
Cause and Solution: As long as your water demands stay fairly consistent, there is no reason for the pump to start kicking on to pump water more than usual. If you start to see this problem, it is a good indication that the check valve is stuck open so pressure is not being regulated as it should. If a manual inspection of the check valve reveals that the valve is stuck open or otherwise defective, it will need to be replaced. To purchase the valve and other well equipment, check out contractors like Modern Pump & Equipment.
Problem: The pump runs, but no water is delivered.
Cause and Solution: This is perhaps the most common problem with well pumps in general and can be caused by a couple of different things. For one, you should check to ensure that the well pump is actually still resting just beneath the water line of the well. If the water level has changed and is too low, it will prevent the pump from doing its job. Another reason for no water being delivered by the pump could be that the water line is clogged with sediment or debris. Pull the pump from the well and clean the inlet valve and line to rectify the situation.
Problem: The motor runs, but the overload breaker constantly trips to interrupt the power.
Cause and Solution: Submersible well pumps are designed with a protective overload breaker that prevents damage to the pump during times of system overload or an overload of connected current. Therefore, if the overload switch continuously trips, it does mean there is an issue that should be resolved. You can check the line terminals of the pump by using a voltmeter. Check the results with the manufacturer's guidelines for your specific pump model to make sure the delivery of current is at an adequate level.
