Well Pump Water Pressure Adjustment

Never adjust the pressure switch above the stage tank s.

Well pump water pressure adjustment. Typical settings for the pump to kick on and off include 20 for pump cut in and 40. Shut the water valve off and pay attention to the pressure gauge to note the pressure when the pump turns off. The well pump water pressure switch controls the rate at which the pump will turn on and off. The switch should never be adjusted to cut on below 20 psi or cut off above 60 psi.

This is the pressure the pump produces when not moving water as with a closed outlet valve. System pressure the pressures in a well pump system must keep a set relationship. The cut on pressure is the low pressure that starts the pump and the cut off pressure is the high pressure that turns off the pump. How to set the water pump cut in and cut out pressures.

Water well pump pressure control switch adjustment. A well pump uses a pressure activated regulator to maintain water pressure. Normally this switch is pre set to the correct pressure but you can modify it without any special tools or materials using just plumbers pliers. The starting and stopping of a well water pump is typically controlled by a pressure switch similar to the one shown below.

The regulator operates within a factory specified range activating the pump as pressure drops and stopping the pump when the pressure rises to a set level. Well pump pressure switch adjusment is a common way to boost your home s water pressure. How to adjust the pump pressure control switch using the square d pumptrol as an example. It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems.

This article describes how to adjust building water pressure by setting the water pump cut in and cut out pressure on the well water pump pressure control switch. To lower any pressure turn the nut counter clockwise. You can make minor adjustments to the pressure regulator with a nut driver. A well s pressure switch turns on the jet pump once the water pressure in the storage tank s bladder drops below a set low limit and turns off the jet pump once the water pressure breaks the high limit setting.

The switch is preset with both the cut on and cut off pressure. There are a variety of causes of potential well water pressure problems but many can be fixed at home. Adjusting the pressure switch changes the high and low water pressure limits.
