Is there a water pump fuse?

Author: Dr. Ward Price Jr.  |  Last update: Saturday, February 28, 2026

Most water pumps don't have an internal fuse. They are normally fused at the power connection…at the plug for mains powered pumps, or at the control panel. So too are low voltage pumps, where the pump supply is tapped off a common line, or an additional in-line fuse (lower rate than the main line rate) if desired.

What would cause the water pump not to turn?

Inspect your breaker box and see if the breaker has tripped, and if it has, then reset it and you should restore power to the pump.

Why would a water pump shut off?

Too Much Air in the Reservoir Tank

In a traditional charged tank, the air pressure inside the tank is used to push water through the lines. However, too much pressure within the reservoir can lead to a problem. If the reservoir pressure is high initially, the pump will cut off much earlier than the optimum level.

Can you reset a water pump?

Hold the reset lever in the start position until the pressure builds up and the gauge reads over 40 PSI; then let it return to the AUTO position. The pump should now run on its own and continue until the pressure reaches the cut out setting, (usually between 50 - 60 PSI), and then shut off.
