The pressure switch to a well pump may shut down a well or cause the water not to flow, especially if both the switch and a pressure tank are affixed to the system. Both parts can cause an over-circulation of water, which, in turn, shuts down a system. The shut-off measure is a safeguard in case a pipe breaks while water is being pumped from the well.Continue Reading
The pressure switch for a well-pumping system typically is found in a gray box that sits on the feed line between the pump and the pressure tank. A silver bar sits next to the box. When the bar is tripped, it rests parallel to the ground. If the trip handle is operational, it sits at approximately a 45-degree angle.
To reset the pressure switch, shut off the water valves, and lift the handle until it is engaged. Allow the tank to fill with water before reopening the valves.
If everything is working correctly, the pressure in the tank should read 2 pounds per square inch less than the setting for the pressure switch. If the setting for the pressure switch is 28 psi, then the tank's reading should be 26 psi.
A power surge can cause a breaker to trip and shut off the flow of water as well. In order to fix the problem, find the pump's circuit breaker, and switch it off and on again.Learn more about Plumbing
To fix low water pressure in a well water pump, inspect the system to find out if there's a problem with hard water buildup that's causing the decline in pressure, advises Wellowner.org. Scale buildup can increase the friction in the pipes, which diminishes the water pressure for the entire system. Removing this scale can increase the pressure.Full Answer >
To install a water pump pressure switch, turn off the power and remove the switch, attach the new switch and replace the pressure gauge. Collect all necessary tools before beginning the project.Full Answer >
To improve water pressure from a water well, turn the power off on the water pump that is connected to the well, and locate the air fill gauge on the top of the pump. Use a tire pressure gauge to check the air pressure, and check the pressure reading on the gauge in the pressure switch box. Remove the cover on the pressure switch box, and adjust the screws inside the box to increase the water pressure.Full Answer >
Well water pressure switches work by detecting the air pressure inside the well's water-holding tank and using this to turn the water pump on and off. When the air pressure in the switch's tube can no longer hold the switch open, it engages the pump.Full Answer >
