We Ensure Superior Water Quality & Well Reliability

The design of water wells has evolved to incorporate many technological advancements. Through our enhanced knowledge, we ensure your well is fully operational and reliable. We also offer well inspections and water testing to resolve any concerns for both geological and man-made wells.

At Carroll Water, we address water quality issues like hard water, unpleasant tastes and odors, and various contaminants. Through professional treatment and testing, we help you protect your groundwater supply. Our solutions include water softeners, iron filters, sulfur removal, chlorination, and more.

Our Services

Well Drilling

We provide well drilling for new homes, commercial buildings, and agricultural properties with wells that have run dry. We start by determining drilling requirements. This involves determining what type of underlying geology we’ll need to drill through, such as gravel, sand, or rock.

We also assess site location, depth, potential volume, the best pump system for your well, and more. Once drilling is complete, we’ll take care of sealing the well, casing and grouting, and construction for optimal efficiency.

Well Inspections

Regular well inspections keep your well operating properly. They’re also crucial for maintaining a safe and reliable water supply. Through comprehensive annual inspections, our experts can identify potential issues before they become serious problems, potentially saving you money on costly emergency repairs.

Comprehensive Water Testing for Bacteria & Overall Water Quality

Wells are often affected by bacteria and other common water issues. This is why we do testing to check bacteria levels and identify other contaminants. This helps us determine your water’s potability.

We recommend annual testing, but it should be done more frequently if:

  • There’s a history of bacteria in your well water
  • Anyone in your household is suffering from gastrointestinal issues
  • A pregnant woman or infant is living in the home
  • You suspect a septic system leak

After testing, we can provide the best equipment to improve your well water quality. With our water testing and treatment services, you can eliminate hard minerals, sulfur odor, nitrates, and other issues.

Well Yield Tests

Well yield tests, also known as well flow rate tests or well drawdown tests, determine how quickly a well refills to its maximum level. Like checking your car’s performance, this test measures your well’s ability to keep up with your daily water needs.

During a test, we:

  • Check water levels before we start
  • Pump water from your well
  • Measure how fast the well refills (by gallons per minute)

This testing helps us:

  • Ensure your well meets your water demands
  • Spot problems early
  • Track your well’s performance over time
  • Plan for any needed upgrades

Low well yield can mean pump problems, mineral buildup, or changes in your groundwater supply. Let Carroll Water test your well’s performance to ensure you always have water when you need it!

Well Pressure Tank Repair & Replacement

A well pressure tank stores water from your well, working alongside your pump to ensure consistent water pressure and supply. This vital component stores water under pressure so it’s ready for immediate use whenever you turn on a faucet or run an appliance.

Some benefits of having a properly functioning pressure tank include:

  • Extended well pump life by preventing frequent on/off cycling
  • Lower energy costs through reduced pump operation
  • Consistent water pressure for better shower and appliance performance
  • Protection against water hammer and pressure surges
  • Optimal well performance and reliability

Signs You May Need Pressure Tank Service:

  • Rapid cycling of your well pump
  • Fluctuating water pressure or short bursts of water pressure
  • Strange noises from your plumbing
  • Higher than normal electric bills

At Carroll Water, we provide complete pressure tank services, including inspection, diagnostics, repairs, replacement, pressure adjustment and calibration, and maintenance. Contact our team for a service appointment!

  • Well Parts

    We carry most well parts needed to get any well up and running again. We can also order items we don’t have on hand. Give us a call, and we’ll assess what parts need replacement in your well so we can restore its operation.

  • Well Pump Replacement 

    Well pumps typically last 8-10 years, though they can last longer depending on design, quality, and usage. When it’s time to replace your well pump, we’ll match the right pump with your well system and daily needs.

    Before we replace the pump, we’ll do an inspection to make sure there aren’t other issues contributing to pump failure.
