Inspecting the well pressure switch is an important step in troubleshooting well pump issues. The pressure switch controls the on/off cycling of the pump based on water pressure in the system.
At the heart of each water well system is a pump, and the most common types are jet pumps and submersible pumps.
If your area you live in does not have a high water table, or if it lacks a stable supply of potable water near the surface, you must dig deeper and a deep well means that the water has to be lifted farther by water well pumps.
