A pressure switch is a device that senses water pressure and turns a pump on or off to maintain a desired pressure range in a water system. In a well pump system, the pressure switch is responsible for starting and stopping the pump to maintain water pressure in the home or building. Setting the pressure switch correctly is essential for the proper operation of the well pump system.
The pressure switch is typically mounted on the well pump or near the pressure tank. It has two main adjustments: the cut-in pressure and the cut-out pressure. The cut-in pressure is the pressure at which the pump turns on. The cut-out pressure is the pressure at which the pump turns off. The difference between the cut-in and cut-out pressure is called the differential. The differential is typically set between 2 and 4 psi.
To set the pressure switch, first, turn off the power to the well pump. Then, open a faucet in the home or building to relieve pressure in the system. Next, adjust the cut-in pressure to the desired value. The cut-in pressure should be high enough to ensure that the pump will turn on when needed but low enough to prevent the pump from cycling on and off too frequently. Finally, adjust the cut-out pressure to the desired value. The cut-out pressure should be high enough to provide adequate water pressure in the home or building but low enough to prevent the pump from running against a closed system.
1. Cut-in pressure
The cut-in pressure is a critical setting on a well pump pressure switch. It determines the pressure at which the pump will turn on to maintain water pressure in the system. Setting the cut-in pressure too high can cause the pump to cycle on and off too frequently, which can shorten its lifespan. Setting the cut-in pressure too low can prevent the pump from turning on when needed, which can lead to a loss of water pressure.
