Why won’t my well water pressure switch turn off?
If the well water pump isn’t creating the appropriate pressure, it won’t signal your pressure switch to turn off and on. Aside from checking the pump, check your water pressure gauge to ensure that it’s working before diagnosing a pressure switch issue. If your pump seems to be cycling (turning on and off repeatedly), there are a few common causes.
Why does my well pump keep cutting out?
If the screen or foot valve and jet is clogged the pump may not be making enough pressure for the pressure switch to reach the cut out pressure. Worn impellers can also reduce pump pressure. I seldom work sandpoint wells and rarely think about the faults of such.
What does a pressure switch do on a well pump?
What a Pressure Switch Does A pressure switch is a switch that signals to the well pump to start or stop pumping depending on the pressure in the water system. Pressure switches are designed to have two pressure settings: cut-in and cut-off pressure.

How do pressure switches work?
Pressure switches are designed to have two pressure settings: cut-in and cut-off pressure . These are the numbers you may find on the switch itself and they typically are 40-60, 30-50 or 20-40 measured in psi. The lower number is the pressure at witch the pump will kick in and start filling up your pressure tank. The higher number is the pressure at which the pump will stop. Both numbers can be adjusted as needed depending on your unique water supply needs.

What is a switch in a car?
The actual switch is a set of points that look like two sets of points in an old car. There are adjustments for the cut in and out pressures. A pump can only produce just so much pressure. The adjustment for shutting off the pump at the higher pressure may be set higher than the pump can produce so it never shuts off.
Why do my contacts pop up on my amp?
If the contacts are sticking together then arcing across them is the culprit. Check connections, verify voltage. Low voltage can cause amp pull to sky rocket. Also if you clean the contacts use nothing rougher than a normal piece of paper. Anything else will ruin them.

What is pressure switch?
The pressure switch comprises a simple internal spring mechanism connected to a set of electrical contacts. Over time, the spring weakens, parts clog with debris, and the electrical contacts corrode and degrade. Even though the switch usually has a sturdy cover, humidity and frequent use all play their part in the inevitable wear and tear of this simple piece of equipment.
