Water Well Basics & Maintenance Guide

What Are the Basic Components of a Water Well System?

A standard water well system consists of a drilled hole that accesses an underground aquifer, a casing to protect the hole, a submersible pump to draw water, and a pressure tank to distribute water into the home. These components work together to provide consistent, clean groundwater.

Understanding water well information starts with knowing your equipment. Here are the core components:

• Well Casing & Cap: The steel or PVC pipe lining the well hole, sealed at the top with a sanitary cap to prevent surface contamination, insects, and debris from entering.
• Submersible Well Pump: Located deep inside the well casing, this motorized pump pushes water up through a drop pipe to the surface.
• Pitless Adapter: A specialized sanitary fitting that connects the well pipe to your home’s underground water line below the frost line, preventing freezing during Colorado winters.

Pressure Tank & Switch: Located inside the home, the pressure tank stores water under pressure. The constant pressure switch signals the pump to turn on when pressure drops, ensuring steady water flow to your faucets.

What Are the Signs Your Well Pump Is Failing?

Signs that your well pump is failing include sputtering faucets, air in the water lines, a sudden drop in water pressure, unusual grinding or clicking noises from the pressure tank, and unexplained increases in your monthly electricity bill.

Even with excellent well maintenance tips, mechanical parts wear out. A standard submersible well pump lasts between 8 and 15 years. If you notice any of the following warning signs, it is time to schedule water well pump troubleshooting and diagnostics:

1. Sputtering Water: Indicates the pump is drawing air, which means it is losing prime or the aquifer water level has dropped.
2. Low Water Pressure: Often caused by a failing pump motor, a waterlogged pressure tank, or a clogged sediment filter.
3. Rapid Cycling: If your pump turns on and off constantly, the pressure tank is likely failing, which will quickly burn out the pump motor.
4. Strange Noises: Grinding, buzzing, or banging sounds from the pump or pressure controls require immediate professional inspection.
5. Dirty or Brown Well Water: Sudden changes in water clarity can indicate a cracked casing or a pump drawing sediment from the bottom of the well.

Frequently Asked Questions

How long does a well pump last?

With proper maintenance, a quality submersible well pump typically lasts between 8 and 15 years. Factors such as water quality, usage volume, and the installation of a constant pressure system can significantly impact this lifespan.

How often should I test my well water?

You should test your well water at least once a year for coliform bacteria and nitrates. You should also test immediately if you notice a change in water taste, odor, or color, or after a major weather event.

Where can I get a water well pump inspection service?

Barnhart Pump Co. provides comprehensive water well pump inspection services throughout the Pikes Peak region. Our inspections cover the well cap, electrical components, pressure tank, and pump performance.

What is a constant pressure system for a well?

A constant pressure system uses a variable-speed motor to maintain steady water pressure throughout your home, regardless of how many fixtures are running at once. It eliminates the pressure drops common in traditional well systems.
