Quick Answer
Common signs of submersible pump failure include reduced water flow, increased power consumption, and unusual noises or vibrations from the pump. Failure to turn on or a sudden loss of flow are also potential indicators. In extreme cases, the pump may even short circuit and cause a fire.
Warning Signs of Failure
A submersible pump failure can occur due to various reasons, including corrosion, electrical issues, or mechanical wear and tear. To identify potential problems, monitor your pump’s performance closely. Check for reduced water flow rates, which may indicate a clogged intake screen or a faulty impeller. If your pump’s power consumption increases significantly, it could be a sign of a faulty motor or a blocked discharge line.
Diagnostic Techniques
If you suspect a submersible pump failure, perform a series of diagnostic tests. Start by checking the pump’s voltage and amperage draw using a multimeter. Measure the water level in the well and the flow rate at the surface to ensure the pump is operating within its designed parameters. Additionally, inspect the pump’s electrical connections and wiring for signs of damage or corrosion.
Preventative Maintenance
Regular maintenance is key to extending the lifespan of your submersible pump. Schedule annual inspections to check for wear and tear on moving parts, corrosion, and electrical issues. Clean or replace the intake screen and impeller as needed, and always follow the manufacturer’s guidelines for maintenance and repair. For wells deeper than 300 feet, consider installing a pressure switch to prevent over-pressurization and extend pump life.
