Master well pumps key terms to deal with your water system needsDealing with a water well may be new to you, if you have always lived in a municipality that supplied water to your home. It can also be a new thing if you've decided to install a well for your garden or lawn irrigation needs. Whatever the situation, you will want to be familiar with well pumps key terms to deal effectively with your water supply needs.
Well pumps come in many forms and sizes. Knowing the key terms of well pumps will help you understand your options for bringing water to the surface, providing pressure and conveying water to the desired fixtures and outlets.
Deep wellThe usual demarcation separating a deep well from a shallow well is 25 feet. Pump manufacturers consider anything beyond the 25-foot depth as being a deep well.
Submersible pumpsAs the name suggests, submersible pumps operate while submersed in the well water. Submersible pumps serve deep wells without the need for priming and without relying on atmospheric pressure to operate.
Control boxWhatever pump you use, you will need controls to turn the pump on and off as you use the water. The control box houses start capacitors and a relay switch that actually turns the pump on and off.
Pressure switchThe pressure switch signals the relay in the control box by sensing the pressure in the water storage tank. When the pressure falls to a certain level, the pressure switch activates the relay, and the pump runs. When the pressure rises to the selected level, the pressure switch deactivates the relay, and the pump stops.
Pressure tankMost well pumps connect to a pressure tank. This serves as a storage tank and also as a way of saving wear and tear on the well pump. Without a pressure tank, the pump would "short cycle," which means it would turn on and off continuously.
