Tips for troubleshooting:

Troubleshooting a water well system starts with simple checks and moves to more complex components such as the power supply, pressure switch, and pressure tank. Common problems include low water pressure, a dry run(weak water well recovery), a pump that won't turn on, or a pump that runs constantly. Begin by checking for tripped breakers or fuses, then inspect the pressure switch for obstructions or damage, and test the pressure tank's air charge.

• If in doubt, when there is NO water, make sure the POWER is OFF until our Mills Pump Service crew arrives and asks to have it turned back on.
  Power issues

• Check breakers and fuses: A tripped breaker is a common cause of the pump stopping. Reset it, but if it trips again, there's likely an underlying problem with the pump. Call us if it trips a second time, as this will require a service call and testing by our technicians.

• Verify the well switch: Ensure the switch located near the pressure tank is in the "on" position.

• Inspect the pressure switch wiring: With the power off, check for loose or damaged connections. Burned contacts or melted wires are signs of a problem. Call MPS for testing at that time.
  Pump and system performance

• Pump runs constantly: A leak in the system is the most common cause. If you don't find a leak, the pressure switch or other components may be failing.

• Pump doesn't run: After checking power, inspect the pressure switch. A plugged nipple can prevent the switch from working correctly.

• Pump doesn't shut off: This can be caused by a plugged nipple in the pressure switch, which prevents the switch from sensing the correct pressure.

• No water: The most common cause is a problem with the pressure switch; you can test it by manually flicking the contacts (with power off). If they spark, the pump is likely working, and the issue is the switch. If they don't spark, the problem could be the pump or wiring.

• Water quality issues: Poor taste or odor can be caused by bacteria, sediment, or other contaminants. This often requires water testing and professional treatment solutions.
  Pressure issues

• Check the pressure tank: its air charge is a frequent cause of low pressure. Turn off the pump, drain the tank, and check the air pressure. It should be 5 PSI below the pressure switch's cut-in pressure. (i.e., if your system starts on 40 psi, then the tank should be 35 psi when empty of all water)

• Clean clogged fixtures: If only one faucet has low pressure, clean the aerator or showerhead to remove mineral buildup.

• Inspect filters and regulators: Check for clogged or dirty filters in the system. A failed pressure regulator can also cause low pressure.

• Look for leaks: A continuous leak can cause the pump to run constantly and lower pressure. Check for wet spots and listen for running water. You can use ball valves to isolate sections of the system to help find the leak. 
  When do you call Mills Pump Service for service? At any time or after trying the above actions.

• If a breaker continues to trip, call MPS.

• For complex electrical issues, use a multimeter to check for voltage (if you wish and can safely do so) at the pressure switch. If voltage is present, but the pump still won't start, it may indicate a faulty pump motor or a myriad of other problems. Stop and Call MPS. You have done what you can.

• If you suspect a broken pipe, pump failure, or dry run where the well does not refill, contact MPS.
