Well Water Pressure Switch Adjustment

The rate of increase is 2 1 2 psi for every complete turn of the nut.

Well water pressure switch adjustment.

If the tank reading is 2 psi under the cut in when you measured it manually but the gauge on the control unit is still low when there s water in it adjust the pressure on your control switch. To improve the well water s pressure requires a few quick adjustments to the pressure tank and pressure switch. 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. Turn off the circuit breaker that supplies power to the well pump and pressure.

The switch is preset with both the cut on and cut off pressure. Adjust the pump pressure control switch if your pressure gauge doesn t match the control unit. The pressure switch is comprised of an internal spring mechanism which is connected directly to electrical contacts. The well pump water pressure switch controls the rate at which the pump will turn on and off.

To increase the cut off and cut on pressure turn nut 1 clockwise. You can adjust the differential by turning the short adjusting nut on the pressure switch clockwise to increase or counter clockwise to decrease the differential it s seldom required and i suggest you not tamper with this setting unless you know what you are doing. Pressure switches with two posts allow adjustment of the cut on and cut off pressure at the same time. At pressure switch nut adjustments in sum it might be possible to improve this condition by adjusting the pump control which sets the cut in water pressure to start the water pump and the cut out water pressure to stop the pump.

The second post allows adjustment of the cut off pressure independently. Basically your pressure switch tells your well pump which delivers water to your home when to turn on and off. As the pressure switch ages these components can weaken and. Range differential adjustment on a water pressure control switch the larger range adjustment nut the larger nut green arrow on the larger spring in the pump pressure switch.

Changes cut in and cut out simultaneously moving them both up higher pressure or down lower pressure. This is the range adjustment nut. It does this by monitoring pressure and letting more water flow into the system when the pressure falls to the minimum psi pounds per square inch.
