Use voltmeter to check at pressure switch or terminals nearest pump | If voltage under recommended minimum, check size of wiring from main switch on property. If OK, contact power company |
| Motor wired incorrectly | Check motor
wiring diagram |
Reconnect for proper voltage as per wiring diagram |
| Inadequate ventilation | Check air temperature where pump is located. If over 100ºF overload may be tripping on external heat | Provide
adequate ventilation or move pump |
| Prolonged low
pressure delivery |
Continuous operation at very low pressure places heavy overload on pump. This can cause overload protection to trip | Install globe
valve on discharge line and throttle to increase pressure |
