Well pumps are essential components for homes, farms, and businesses across the United States that rely on well water for daily use. These pumps deliver water from underground sources to your home or property, providing drinking water, irrigation, and other essential needs. When a well pump stops working or malfunctions, it can disrupt water supply and cause significant inconvenience. Knowing how to identify, troubleshoot, and repair common well pump issues ensures a reliable water system.
Whether you encounter a well water pump not working, a well pump not turning on, or pressure inconsistencies, understanding the underlying causes can save time, effort, and prevent costly repairs. Professional well pump service is often necessary, but many common problems can be identified and managed by homeowners with basic technical knowledge.
What a Well Pump Does
A well pump is a mechanical device that draws water from a well and sends it to your plumbing system. There are two main types of well pumps commonly used in the United States:
-
Submersible Pumps – Installed directly in the water well, these pumps push water up from deeper sources. They are efficient for deep wells and typically operate quietly.
-
Jet Pumps – Located above ground, jet pumps pull water using suction and are suitable for shallow wells.
Well pumps operate in conjunction with a well pressure switch, which controls the pump by turning it on or off depending on the water pressure in the storage tank. If the pump fails to respond, the water supply can be interrupted, signaling the need for troubleshooting or repair.
Common Signs That a Well Pump Needs Repair
Identifying early signs of well pump failure helps prevent major issues. Some common indicators include:
-
Well pump not working – No water comes from taps, and the pump motor may not start.
-
Well pump stopped working – The pump may have shut off due to electrical issues or safety mechanisms.
-
Low water pressure – Reduced flow may indicate pump wear, clogged pipes, or pressure tank issues.
-
Unusual noises – Grinding, humming, or rattling sounds from the pump often indicate mechanical problems.
-
Pump cycles frequently – A well pump turning on and off too often may signal a pressure switch or tank problem.
-
Water discoloration or sediment – Could indicate a worn pump impeller or contamination in the well.
Recognizing these symptoms allows homeowners to act quickly and arrange well pump service before extensive damage occurs.
