FAQ

What are the 3 wires on a well pump?

In a 3-wire well pump setup, the motor is connected using a black, red, yellow, and green (ground) wire. These pumps have a separate control box located outside the pump itself. This control box contains essential starting components and is typically mounted on a nearby wall at a height above the ground. This configuration ensures efficient and safe operation of the well pump system.

How does a well pump pressure switch work?

This device is designed to detect pressure changes in your home’s plumbing system. It uses a small diaphragm and spring mechanism to control the activation and deactivation of the well pump. The switch can be adjusted to specific pressure settings based on the unique design of your plumbing system.

What is the normal pressure switch on a well pump?

A well pressure switch is responsible for activating and deactivating a well pump based on the pressure levels in the system. When the pressure drops to a specific point called the cut-on point, the switch turns on the pump. Conversely, when the pressure rises to the cut-off point, the switch shuts off the pump. In well systems, typical pressure thresholds include 40 and 60 psi, 30 and 50 psi, and 20 and 40 psi. These thresholds determine the desired pressure range for optimal functioning of the well system.
