Submersible well pumps are necessary for extracting water from deep underground sources. If your pump isn’t operating as planned, you need to know how to test it. In this article, we’ll walk you through the process of testing a submersible well pump, ensuring that you can detect problems before they become more serious.
What Is Submersible Well Pumps
A submersible well pump functions underwater, pushing water to the surface via a conduit. Submersible pumps, unlike jet pumps, are meant to be fully immersed. This design has various advantages, including higher efficiency and lower noise levels. However, they can fail over time, usually owing to electrical problems or wear and tear. Understanding how to test a submersible well pump can help you keep it in good condition.
Signs of a Failing Submersible Pump
Before getting into the testing techniques, it’s critical to understand the symptoms of a faulty submersible pump. Common symptoms include:
- Insufficient water pressure
- fluctuating water levels
- unusual noises from the pump
- Water Quality Issues
If you observe any of these signs, it’s time to examine them deeper.
How to Test a Submersible Well Pump
Safety First
Before doing any experiment, check your safety. To avoid electrical shock, disconnect the pump’s power supply. Always wear safety equipment, like gloves and glasses, to protect yourself during the procedure.
How to Test a Submersible Water Well Pump
To begin testing, you can evaluate the pump’s performance. Take these steps:
Measure Water Output: Use a flow meter to determine how many gallons per minute (GPM) the pump delivers. Compare this to the pump’s specs. A substantial decline suggests a concern.
Check Pressure: Using a pressure gauge, test the pressure at the discharge line. Abnormal readings may indicate a blockage or pump failure.
Testing 2 Wire, 3 Wire, and 4 Wire Submersible Pumps
Submersible well pumps are available in three configurations: two-wire, three-wire, and four-wire. Each category demands a somewhat different testing strategy.
How to Test a 2 Wire Submersible Well Pump
For a two-wire pump, simply verify the voltage provided to it. Use a multimeter to confirm that the voltage matches the desired value. If there is no voltage, the fault may be with the control box or the circuit.
How to Test a 3 Wire Submersible Well Pump
Testing a three-wire pump requires several procedures. Here’s a simple procedure:
- Check the power supply: Again, use a multimeter to measure voltage.
- Inspect the wiring: Check for evidence of damage in the wiring. A frayed cable might cause performance concerns.
- Test the motor: If the wiring is intact, use an ohmmeter to verify the motor’s continuity.
How to Test a 4 Wire Submersible Well Pump
Testing a four-wire pump is identical to testing a three-wire pump; however, testing the ground wire requires additional procedures. Follow these steps:
- Measure Voltage: Check the voltage of the power supply.
- Inspect all wires: Ensure that all four wires are in good condition.
- Test the ground: Ensure that the ground wire is firmly attached and operating properly.
How to Test a Submersible Well Pump Motor
To fully evaluate the motor’s condition:
- Check for a burnt smell: A burned odor signals a possible motor failure.
- Perform an Ohm Test: With a multimeter, measure the resistance across the motor windings. Compare the readings to the manufacturer’s specs.
How to Bench Test a Submersible Well Pump
If you’ve removed the pump, you may bench-test it. This strategy enables a full evaluation.
- Connect to a regulated power source to power the pump.
- Observe performance. Keep track of how the pump performs. Check for leaks and strange noises.
How to Ohm Test a Submersible Well Pump
An ohm test is critical for determining the integrity of the motor windings:
- Disconnect electricity: Always turn off the electricity before starting.
- Measure Resistance: Using a multimeter, measure the resistance across each motor terminal.
