Is your well running dry? You might have pressure switch problems.

Over 34 million Americans rely on a well for access to water. Well owners know the importance of identifying and resolving issues themselves when possible.

Below, we’re taking a look at seven common well pump pressure switch problems.

Switch Won’t Turn On

If your switch won’t turn on, this could be a sign your tank pressure is above your switch’s cut-in pressure. 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.

Switch Won’t Turn Off

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.

Check your water supply from the well, along with any leaks which could be affecting your pressure cut-off.

Switch Clicks On and Off

If your pump seems to be cycling (turning on and off repeatedly), there are a few common causes. One of the most frequent culprits is a blown bladder in the water tank. You’ll need to replace this component, and also inspect the switch contacts to see if they’ve suffered any damage from the cycling.

Pressure Sensor Clogging

If you live in an area with high mineral content or sediment in your water, your pressure sensor can become clogged.

Try cleaning the tube that connects your switch to the water supply. You may also need to clean the bottom of the switch itself. If you have enough debris to cause a clog, however, it’s often more economical to replace the switch.

Damaged Diaphragm

Water from your supply creates pressure against the diaphragm of the switch to give a pressure reading. When the diaphragm is old, wear and tear can prevent it from sensing the correct water pressure. If this occurs, it’s time to buy a replacement switch.

Failed Connection

A malfunction in your switch could indicate a problem elsewhere in the system. For instance, if your piping is of the wrong size, it can cause a leaky connection. This will stop the pressure switch from doing its job effectively.

Inspect your piping to ensure you’re using the right diameter for the job. Look for any leaks or signs your pipe doesn’t fit snugly to the switch.

Bad Contacts

The electrical contacts in your pressure switch can degrade over time. Frequent cycling of power to the switch and the presence of corrosive substances are two common causes.

You make a temporary repair to contacts by filing away the affected area, though be sure to kill all power to the pump before you do. For a more permanent fix, you’ll need to replace the switch.
