What is a pressure switch?
A pressure switch is typically used to turn a jet pump or submersible well pump on and off. The pressure switch signals the pump to start when the water system drops to a set PSI and off when the system increases to a set PSI. They can be wired to work with 115 or 230 volts. Pressure switches must be used with a pressure tank.
Can I adjust my pressure switch?
Yes, pressure switches are adjustable. They are typically preset at 30/50 (on at 30 PSI, off at 50 PSI) or 40/60. There is a nut to adjust the differential and a nut to adjust the range. Check out our blog or YouTube videos below:

What should my settings be?
If you are a homeowner, whether you have your pressure switch set at 30/50 or 40/60 is a matter of personal preference. You will need to take into consideration whether you are satisfied with the amount of water pressure in the different areas of your home. For a single level home or a two story home without water fixtures on the 2nd floor a 30/50 PSI setting may be sufficient. For two or more levels with water fixtures on more than one level you may want to use 40/60 PSI setting

What is my pressure switch currently set at?

What is a low pressure cut-off switch?
Some switches come with a low pressure cut-off switch. The low pressure attachment drops to turn off the pump when it loses its prime and the pressure drops to a specific low pressure cut-off point.
