What is a water pressure switch?
Pressure switches monitor your water system to electrically “start” or “stop” your pump at pre-set water system pressures. Pressure switches are used on submersible, reciprocating and jet pump systems. Water is pumped into a well tank to compress the air that provides water under pressure when the pump is not running.
Are well control boxes interchangeable?
Control box with pressure switch and disconnect regulates supply of power to the pump motor at the bottom of the well. As for the others, motors and control boxes may be interchanged as long as horsepower, phase, and voltage are a match.
What kind of pressure switch do I need for jet pump?
Product Overview. This switch is to be used with submersible well or jet pumps. It can be wired 115-Volt or 230-Volt. This switch must be used in conjunction with a well pressure tank. The air pressure in the well tank, when empty of all water, must be set to 38 psi or the switch will not operate properly.
What can I do if my water pressure switch is not turning off?
Try running some water elsewhere in the building to reduce pressure below the cut-in level. You can also try gently tapping on the pressure gauge, the switch, and the tank. Several problems can prevent a pressure control switch from turning off. It’s important to cut power when this happens so the switch won’t burn out.
Can a pressure switch be wired to a well tank?
It can be wired 115-Volt or 230-Volt. This switch must be used in conjunction with a well pressure tank. The air pressure in the well tank, when empty of all water, must be set to 38 psi or the switch will not operate properly.
Where to place the pressure switch on a hydro tank?
Installing the pressure switch on the top or air side of these hydro tanks has been the norm. Placing the pressure switch on the air side of the tank eliminates any possibility of hydraulic shock on the pressure switch. Newer systems using bladder type tanks rarely have this option.
Where is the pressure switch on a water pump?
Pressure Control Switch location: in commercial or large building water supply systems using bladderless-type water pressure tanks check that the pressure control is mounted at a tapping on the tank top or high on the tank side (above the water level).

How to change the air pressure in a water tank?
Here is the procedure: Close off all plumbing fixtures that are using water in the building. Turn on the water pump and let the system run until the water pump cuts off. Open one or more plumbing fixtures to drain the water pressure tank; during this draining, watch and listen to the water… If
Why is my pressure tank not holding water?
Air up the pressure tank as suggested. If it won’t hold pressure while not in use, then the bladder is leaking. Don’t worry about going to the pressure switch until you eliminate the pressure tank. Pressure is the resistance to movement of the water. The pump moves water, the resistance increases pressure and the switch opens to shut off the pump.
