Well Pump Water Pressure Adjustment

How to set the water pump cut in and cut out pressures.

Well pump water pressure adjustment.

The well pump water pressure switch controls the rate at which the pump will turn on and off. Adjusting the pressure switch changes the high and low water pressure limits. System pressure the pressures in a well pump system must keep a set relationship. The switch is preset with both the cut on and cut off pressure.

A well pump uses a pressure activated regulator to maintain water pressure. Water well pump pressure control switch adjustment. 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. Typical settings for the pump to kick on and off include 20 for pump cut in and 40.

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. To lower any pressure turn the nut counter clockwise. Shut the water valve off and pay attention to the pressure gauge to note the pressure when the pump turns off. You can make minor adjustments to the pressure regulator with a nut driver.

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. Here we are discussing setting the water pressures at which a water pump will turn on to get more water and off to stop pumping water from the water source into the water tank. There are a variety of causes of potential well water pressure problems but many can be fixed at home. 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 starting and stopping of a well water pump is typically controlled by a pressure switch similar to the one shown below. This is the pressure the pump produces when not moving water as with a closed outlet valve. It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems. How to adjust the pump pressure control switch using the square d pumptrol as an example.

Never adjust the pressure switch above the stage tank s. If your home s water supply comes from a well you may notice issues with low water pressure. 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.
