Professional flushing and descaling to restore hot water, improve efficiency, and extend the life of your tankless system. Choose Wadford Water Works for yearly cleaning that prevents scale buildup, saves energy, and keeps water hot.
Your tankless water heater works hard every day to give you endless hot water for showers, laundry, and dishes. Charleston water, both municipal and private, often leaves behind mineral depostits. Over time, this chalky buildup (called scale) coats the heat exchanger and internal parts of your system. Without regular cleaning, your tankless water heater can lose efficiency, produce lukewarm water, or even fail prematurely. That’s why most manufacturers recommend a professional tankless water heater flush and descaling every 12 months. At Wadford Water Works, we provide expert tankless water heater cleaning in Charleston, SC to keep your system running at peak performance.
Mineral scale builds up fastest on the heat exchanger (the part that actually heats your water). Just a thin layer can:
Reduce water pressure and slow flow rates
Cause inconsistent or lukewarm water
Make your heater work harder (higher energy bills)
Shorten the lifespan of your water heater
Even Charleston’s moderately soft city water leaves deposits over time, and well water across the Lowcountry often contains high levels of minerals. An annual cleaning ensures your system runs efficiently year-round.
When you schedule your tankless water heater maintenance in Charleston, our technicians perform a full system service:
Heat Exchanger Flush & Descale – Removes mineral buildup with a safe descaling solution.
Filter Inspection & Cleaning – Keeps water flowing freely through the unit.
Safety & Combustion Check – Burner/igniter inspection, venting check, and leak detection.

Here are some of the most commonly asked questions about Alkaline water treatments from our customers
Absolutely. We always perform a Charleston water quality test first to measure pH, minerals, and contaminants. That way, we can recommend the right system for your home. You may benefit from alkaline water filtration if you notice:
Blue or green stains in sinks, tubs, or toilets
Sour, metallic, or bitter drinking water
Corrosion or leaks in copper pipes
Frequent appliance repairs or replacements
Dry skin or brittle hair after showering
Even if your water looks clear, pH water testing in Charleston often reveals hidden acidity that could be damaging your plumbing.
Yes. Naturally mineralized alkaline water improves taste, protects plumbing, and supports hydration with added calcium and magnesium.
The EPA recommends between 6.5 and 8.5. Many Charleston wells test below 7, which can cause corrosion and taste problems.
Bottled water is temporary. A whole-home alkaline system treats all the water in your home, protecting your pipes, appliances, and family long-term.
Most systems require periodic refilling of the calcite mineral bed every 12–24 months, depending on water usage and acidity levels.
