Booster pump pressure switch

A pressure switch is a device that is commonly used to control the operation of booster pumps. The switch is typically installed in the piping system between the pump and the water storage tank or pressure vessel. Here's how it works:

1. The pressure switch has two adjustable settings: the cut-in pressure and the cut-out pressure. The cut-in pressure is the point at which the switch will turn the pump on, and the cut-out pressure is the point at which the switch will turn the pump off.
2. When the water pressure in the piping system drops below the cut-in pressure, the pressure switch will activate and turn on the booster pump.
3. The pump will continue to operate until the water pressure in the piping system reaches the cut-out pressure, at which point the pressure switch will deactivate and turn off the pump.
4. The pressure switch will continue to monitor the water pressure in the system and activate the pump as needed to maintain the desired water pressure.

If you need to adjust the pressure switch settings, you can do so by turning the adjustment screws located on the switch. Typically, the cut-in pressure is set to 2-3 psi below the cut-out pressure, and the cut-out pressure is set to the desired maximum water pressure for the system.

It's important to note that improper adjustment or failure of the pressure switch can result in pump damage or system failure, so it's important to ensure that the switch is properly installed and maintained.
