Quick Answer
A submersible pump may need replacement if it's producing lower water flow rates, making loud noises, or exhibiting a high power consumption. You might also notice a decrease in water pressure, or the pump fails to turn on.
Signs of Wear and Tear
A submersible pump’s motor and impeller are prone to wear and tear over time. Check for signs of corrosion, mineral buildup, or worn-out components, such as worn-out seals, clogged intake screens, or damaged impellers. For instance, if your pump’s flow rate has decreased by 20% or more, it may indicate a clogged impeller or screen that needs cleaning or replacement.
Increased Power Consumption
If your submersible pump is consuming significantly more power than usual, it could be a sign that the motor is failing or that there’s a problem with the electrical connections. Check the power consumption by comparing it to the manufacturer’s specifications or previous usage. If the power consumption has increased by 30% or more, consider replacing the pump.
Failure to Turn On
If your submersible pump fails to turn on, check the electrical connections and the circuit breaker. Also, ensure that the pump is properly submerged in water and that the float switch is functioning correctly. If the issue persists, it may be due to a faulty motor or a problem with the pump’s control system. In such cases, replacing the pump might be the best option.
