How to Test a Submersible Water Well Pump


Testing a submersible water well pump is crucial to ensure its efficiency and longevity. A properly functioning pump is essential for providing a reliable water supply for households, irrigation, and other needs. If you suspect your pump is not working as it should, performing a systematic test can help diagnose any issues. Here’s how to test a submersible water well pump effectively.


Safety First


Before conducting any tests, make sure to prioritize safety. Turn off the power supply to the pump at the circuit breaker to prevent any electrical hazards. Wear protective gear such as gloves and safety goggles, especially if you will be handling water and electrical equipment.


Gather Necessary Tools


You will need a few tools to test your submersible pump. These may include - A multimeter to measure electric current and voltage - A flow meter to measure the water output - A pressure gauge to check the water pressure - A bucket or container to collect water - A wrench set for removing fittings if necessary


Step 1 Inspect the Pump


Begin by inspecting the visible components of the pump. Check for any obvious wear or damage to the electrical connections, casing, and discharge pipe. Look for any signs of leakage or corrosion. If your pump is still submerged, ensure that the power is off before proceeding with further inspections.


Step 2 Measure Voltage and Current


Using a multimeter, check the voltage at the pump’s electrical connections. The voltage should match the specifications indicated on the pump’s nameplate. If the voltage is low or inconsistent, the issue may lie with the electrical supply or the wiring.

Next, measure the current draw of the pump while it is running. Compare this reading to the recommended amperage in the pump specifications. An amperage that is too high can indicate that the pump is working harder than it should, potentially leading to failure.


Step 3 Test Water Flow and Pressure


With the pump powered on, collect water in a bucket for a set amount of time (usually one minute). Measure the volume of water collected. This value will give you the flow rate of the pump, which should align with the manufacturer’s specifications.


In addition to measuring flow, attach a pressure gauge to the outlet pipe of the pump to check the water pressure. The pressure should generally fall within a specific range as outlined by the pump’s manual. Low pressure can indicate a blockage, while high pressure could signal a problem with the pump or system configuration.


Step 4 Evaluate Performance


After gathering data on voltage, current, flow rate, and pressure, evaluate the performance of your pump. If any of the measurements are off from the manufacturer’s specifications, it is essential to address the issues. Possible problems could include clogged filters, worn-out motor bearings, or a malfunctioning pressure switch.


Step 5 Troubleshooting and Maintenance


If the performance is not satisfactory, consult the pump’s manual for troubleshooting advice. Routine maintenance is vital for ensuring the longevity of your submersible pump, so consider implementing a regular inspection schedule. This may include checking wiring, cleaning filters, and replacing worn components.


Conclusion


Testing a submersible water well pump can seem daunting, but breaking it down into clear steps simplifies the process. Regular testing not only helps you identify potential problems early but also extends the life of your pump. By ensuring your submersible pump operates effectively, you can maintain a consistent and reliable water supply for your needs. Should you encounter persistent issues, consider consulting a professional to provide further assistance and repairs.
