Well Pump Water Pressure Adjustment

Water well pump pressure control switch adjustment.

Well pump water pressure 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. 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 should never be adjusted to cut on below 20 psi or cut off above 60 psi. System pressure the pressures in a well pump system must keep a set relationship.

How to set the water pump cut in and cut out pressures. Typical settings for the pump to kick on and off include 20 for pump cut in and 40. Adjusting the pressure switch changes the high and low water pressure limits. It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems.

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. Shut the water valve off and pay attention to the pressure gauge to note the pressure when the pump turns off. 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.

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. The starting and stopping of a well water pump is typically controlled by a pressure switch similar to the one shown below. To lower any pressure turn the nut counter clockwise. We explain which adjustment nuts to turn and in which direction to change pump cut in pressure or cut our pressure settings.

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. You can make minor adjustments to the pressure regulator with a nut driver. This is the pressure the pump produces when not moving water as with a closed outlet valve.

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. The well pump water pressure switch controls the rate at which the pump will turn on and off. 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.
