What happens when a pressure switch on a well goes bad?

You’ll find the pressure switch mounted on a 1/4-in. tube near the pressure tank. It’s what senses when water pressure has dropped to the point where the pressure tank requires more water. If the switch is bad, it won’t start the well pump and you won’t have water, so testing the switch is your first step.

What does a low pressure cut off switch do?

What does a Low Cut-Off Pressure Switch do? A low cut off pressure switch turns the pump off in the event that the water pressure in your lines drops lower than the cut-in pressure (low number). Imagine that there was a leak or break in your water line.

What is the difference between a pressure switch and a low pressure switch?

A high-pressure switch is connected to the discharge, or “high” side of the system to sense discharge pressure. A low-pressure switch is connected to the suction, or “low” side of the system to sense suction pressure.

What causes pressure switch failure?

A high reading means the pressure switch has failed. Check for a clogged hose port or cracked hose running from the draft inducer motor or condensate collector box to the pressure switch. These problems can cause the switch to trip or fail.

What does a pressure switch on a well do?

If you have a private well water system, your pressure switch is an integral component. The pressure switch tells the pump that delivers water to your home when to turn on and off. When the pressure in the system drops to a preset low setting the pump will turn on (commonly known as the cut-on pressure).

What does a low cut off pressure switch do?

A low cut off pressure switch turns the pump off in the event that the water pressure in your lines drops lower than the cut-in pressure (low number). Imagine that there was a leak or break in your water line.

What is the low pressure cut off range?

The adjustable differential range is 15 psi to 30 psi and the cut-out range is 20 psi to 65 psi. The low-pressure cut-off (auto-start-off) operates at approximately 10 psig below the cut-in and will turn off the pump.

How does a low pressure water pump switch work?

Low pressure cut-off pressure switches turn the pumps off if the water pressure dips below 15 psi. In this video tutorial, we explain how these switches work, and the pros and cons in using them with your pump installation. Should I use a rain harvesting system to irrigate my lawn?
