Quick Answer
A jet pump malfunction can be indicated by a sudden drop in water pressure, increased power consumption, or unusual noises such as hissing, gurgling, or whining sounds.
Common Red Flags
A jet pump malfunction can be caused by various factors, including worn or damaged seals, clogged or dirty intake screens, and low water pressure. Inspect the pump’s impeller and check for any blockages in the suction line. A 1/4 inch restriction in the suction line can reduce pump performance by up to 50%.
Troubleshooting Techniques
If the pump is making unusual noises, check the pump’s motor for any signs of overheating. A temperature rise of more than 10°F above normal operating temperature can indicate a malfunction. Use a multimeter to check for any electrical issues, such as a short circuit or open circuit.
Maintenance and Inspection
Regular maintenance is key to preventing jet pump malfunctions. Inspect the pump’s intake screen and clean or replace it as needed. Check the pump’s suction line for any kinks or blockages and straighten or replace it if necessary. Consider using a water flow meter to monitor water flow and pressure, allowing you to catch any issues before they become major problems.
