Well Water Pressure Switch Adjustment

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

Well water pressure switch adjustment. 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. Pressure switches with two posts allow adjustment of the cut on and cut off pressure at the same time. Turn off the circuit breaker that supplies power to the well pump and pressure.

It makes use of two pressure systems to control the water flow and adjusting the water pressure involves adjusting these systems. The rate of increase is 2 1 2 psi for every complete turn of the nut. The starting and stopping of a well water pump is typically controlled by a pressure switch similar to the one shown below. Adjust the pump pressure control switch if your pressure gauge doesn t match the control unit.

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. To improve the well water s pressure requires a few quick adjustments to the pressure tank and pressure switch. As the pressure switch ages these components can weaken and. 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. 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. To increase the cut off and cut on pressure turn nut 1 clockwise. 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.

Changes cut in and cut out simultaneously moving them both up higher pressure or down lower pressure. It turns off when the maximum psi is reached. The second post allows adjustment of the cut off pressure independently.
