Quick Answer
A failing jet pump may exhibit signs such as reduced water pressure, decreased flow rate, and increased power consumption. It may also produce unusual noises, such as loud hissing or gurgling sounds, and may not shut off properly when the tank is full. These symptoms can indicate a need for maintenance or repair.
Common Signs of a Failing Jet Pump
A failing jet pump can be identified by paying attention to changes in water pressure and flow rate. Typically, a healthy jet pump should be able to maintain a flow rate of at least 5-7 gallons per minute (gpm) at 30-40 feet of head pressure. If the flow rate drops below 3-4 gpm, it may be a sign of a failing pump.
Troubleshooting Techniques
When troubleshooting a failing jet pump, check the power cord and electrical connections for any signs of damage or wear. Ensure that the pump is properly installed and leveled, as uneven installation can cause vibration and premature wear. It’s also essential to check the water level in the well and the tank to ensure that they are at the recommended levels.
Advanced Diagnostic Techniques
If the pump is still under warranty or if you’re not comfortable with DIY troubleshooting, it’s recommended to hire a professional to inspect the pump and diagnose the issue. In some cases, a failing jet pump may require replacement of the motor, impeller, or other critical components. Advanced diagnostic techniques may involve using specialized equipment such as a multimeter to measure electrical resistance and voltage, or a pressure gauge to measure pressure drops across the pump.
