Well Water Pressure Switch Adjustment

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.

Well water pressure switch adjustment.

Changes cut in and cut out simultaneously moving them both up higher pressure or down lower pressure. The rate of increase is 2 1 2 psi for every complete turn of the nut. It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems. To increase the cut off and cut on pressure turn nut 1 clockwise.

The starting and stopping of a well water pump is typically controlled by a pressure switch similar to the one shown below. Turn off the circuit breaker that supplies power to the well pump and pressure. This is the range adjustment nut. The second post allows adjustment of the cut off pressure independently.

As the pressure switch ages these components can weaken and. Pressure switches with two posts allow adjustment of the cut on and cut off pressure at the same time. 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. 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.

Adjust the pump pressure control switch if your pressure gauge doesn t match the control unit. To improve the well water s pressure requires a few quick adjustments to the pressure tank and pressure switch. 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. The switch is preset with both the cut on and cut off pressure.

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. Basically your pressure switch tells your well pump which delivers water to your home when to turn on and off.
