What to Know About Well Water Systems & Associated Upkeep

By /

It’s important to understand how well water systems work and what it takes to keep them in good shape. Unlike city water, which is managed by the local utility company, a well water system is something you’re responsible for maintaining yourself.

That means staying on top of testing, maintenance, and any repairs that come up. It can sound like a lot, but with the right knowledge and a good inspection, it’s very manageable. Here’s what to know about what tends to go wrong and what to watch out for.

How a Well Water System Works in a Residential Setting

A well water system pulls groundwater from deep underground and brings it into your home. It sounds simple, but there are several parts that all need to work together:
  • The well: A hole drilled into the ground that reaches the water supply below
  • The pump: Moves water from the well into your home
  • The pressure tank: Keeps water flowing steadily and stores extra for demand
  • Filters or treatment systems: Optional, but often used to improve taste and safety
Many homes in rural or outlying areas around Charlotte use well systems instead of city water. They give homeowners more independence, but also more responsibility when it comes to keeping the water clean and the system running smoothly.

Common Issues Found in Well Water Systems

Even when a well water system seems to be working fine, there can be issues happening behind the scenes. During inspections, we often come across:
  • Sediment or mineral buildup that can clog pipes or stain fixtures
  • Low water pressure from worn-out pumps or faulty tanks
  • Strange smells or tastes, like sulfur or metal, which could signal a water quality issue
  • Signs of contamination, especially from bacteria or nearby surface pollutantsThese problems might not be obvious at first, but they can affect your water quality, plumbing, and even your health. That’s why it’s important to have a professional take a close look—especially if you’re buying a home with a well and don’t know its history.

How Often Should You Inspect or Test a Well Water System?

It’s a good idea to test your well water at least once a year. The CDC recommends checking for things like:
  • Bacteria
  • Nitrates
  • pH levels
  • Other potential contaminants
If you’ve had recent flooding, heavy storms, or construction nearby, you should test more often. Inspections should also happen:
  • When you’re buying or selling a home
  • If your water changes in color, taste, or smell
  • If your water pressure suddenly drops or becomes inconsistent
At AHI, we check the visible parts of the well water system as part of our general home inspections. While we don’t perform lab testing, we flag signs of trouble and help homeowners understand when additional testing is needed.

Basic Upkeep for Homeowners Using Well Water

Owning a home with a well doesn’t have to be stressful. A few regular habits can go a long way toward keeping your water safe and your system running well:
  • Keep the area around the well clean and free from chemicals or debris
  • Check your pressure tank every now and then for short-cycling or odd sounds
  • Change water filters regularly if your system uses them
  • Pay attention to changes in water quality—cloudiness, smell, or taste
It also helps to keep a simple log of any maintenance, filter changes, or testing you’ve done. If a problem comes up later, or if you decide to sell your home, those records can be really useful.

Other Recommended Maintenance

In addition to basic upkeep, here are a few other smart steps to take:
  • Get a professional water test once a year—especially if you’ve never had one done
  • Have your pump and pressure tank inspected every few years
  • Flush your system if you notice sediment collecting in your water
Even if everything seems fine, wells can develop problems slowly. A little preventative maintenance helps catch small issues before they become expensive repairs—or health concerns.

When to Call a Professional

Sometimes, well water issues need expert attention. You should contact a pro if you notice:
  • Sudden drops in water pressure
  • Water that smells bad or looks cloudy
  • A pump that runs constantly or makes loud noises
  • Any unexplained changes in your water quality
These could be signs of pump failure, contamination, or other serious problems. If you’re buying a home with a well water system, getting a professional inspection is a smart move. At AHI, we’ve inspected hundreds of homes with well systems and know what to look for.
