Where do the wires go on a pressure switch?

A wiring diagram is normally found on the inside of the cover. Loosen (do not remove) the screws on the pressure switch terminal with a screwdriver by turning in a counterclockwise direction. Feed wires from the pump motor and main power supply through the openings on either side of the switch.

Can you wire a well pump backwards?

The pump is AC so you cannot make it run backwards by reversing the leads. Likewise, you cannot hook it up so that it’s lifefspan will be reduced. It will either work or trip a breaker.

What happens if you run a water pump backwards?

If the motor and pump are running backwards, the pump can often still move water, and the water will flow the normal direction through the pump. A backward running pump will deliver less water, at a lower pressure, and will typically consume less electricity.

What happens if you wire a pump backwards?

A common myth is that in reverse rotation, the pump causes backward flow, that is, IN the discharge and OUT the suction. In reality, a pump operating in reverse rotation because of wiring or phase change will pump in the normal direction. Now, it won’t pump very well. Its flow will be reduced, as will its head.

How do you replace a well pressure switch?

Replace a pressure switch for a water well by turning off the power, disconnecting the wiring, draining the tank, removing the old switch and installing the new one. All pressure switches eventually require replacement.

How to test a well pressure switch?

Remove the metal or plastic cover from the pressure switch. You may need a screwdriver to remove a couple of screws first.

Check and clean the switch relay contacts. Examine the four contacts for burning or pitting on the surface.

Make sure the wires are making full contact and are firmly secured by their screws.

Find the pressure adjustment nut,typically located near the front of the compartment next to the switch relay contacts.

How do you test a pressure switch?

To test the pressure switch we need to use a multimeter and measure the continuity of the switch as it opens and closes. A multimeter will be needed to test the switch for continuity. Basically The switch needs to be tested to see if it is closing when the pressure diaphragm pulls in.

What is a well water pressure switch?

A pressure switch is the mechanism that will turn on and turn off the well pump based on the pressure in the water system. Most switches we use are 40-60 switches, meaning that the switch will activate your pump to turn on when the water pressure lowers to 40 lbs. and will kill power to your pump when the water pressure reaches 60 lbs.
