In 2026, the cost of replacing a water heater continues to rise alongside higher utility costs and equipment prices.

Flush Water Heater Service
Removing sediment buildup is one of the most important parts of water heater maintenance. Over time, minerals settle in the tank and form a hardened layer of debris between the heating source and the water.
This buildup can:
As sediment builds up, technicians often call it a “mineral blanket” that forms across the bottom of the tank. The burner has to heat this hardened layer before it can heat the water. That extra strain can overheat the tank, weaken the glass lining, and accelerate system failure. Here is often the sound of trapped water boiling beneath hardened sediment — and of the water heater’s lifespan being shortened.
Our professional flush service removes this buildup before it causes long-term damage. This is particularly important in Lexington and Richland Counties, where mineral-rich water conditions are common
Tankless Water Heater Maintenance
Tankless systems require specialized maintenance to operate efficiently. If you skip yearly descaling and cleaning, mineral buildup can block water flow and damage internal parts.
Our tankless maintenance service may include:
Regular maintenance helps your tankless water heater run efficiently and last longer.
Why Water Heaters Work Harder in the Midlands
South Carolina’s climate and water put extra stress on water heaters in this area.
Hard Water & Sediment Problems
Mineral-rich water in Lexington and Richland Counties speeds up sediment buildup in both tank and tankless systems.
This is especially common in:
If you don’t regularly flush and maintain your system, mineral buildup can significantly reduce its performance and shorten its lifespan.
The “Lake Murray Humidity” Factor
Homes near Lake Murray, Chapin, Yacht Cove, and other waterfront areas often have higher humidity, which can lead to more corrosion in plumbing systems.
For gas water heaters, humidity may also affect:
Regular inspections catch corrosion problems early, before they turn into safety or efficiency issues.
Water Pressure & Expansion Protection
As Red Bank, Gilbert, and other Midlands communities grow, changes in infrastructure have made fluctuations in water pressure more common.
High water pressure places constant stress on:
During maintenance visits, we inspect:
If your Pressure Reducing Valve (PRV) is failing, it’s like leaving a balloon overinflated. Sooner or later, something will break.
Regular maintenance helps spot these pressure problems before they cause leaks, tank damage, or plumbing failures.
What’s Included in a Water Heater Tune-Up?
A professional water heater tune-up finds problems early, before they turn into costly repairs. Maintenance services include:
We check every system based on its age, condition, usage, and local water quality.
Kay Comfort Club Membership Protection
Regular maintenance is one of the best ways to protect your plumbing investment for the long run.
Our Kay Comfort Club membership helps you avoid costly breakdowns with scheduled inspections and preventive maintenance.
Membership benefits may include:
During maintenance, we also check your water heater’s sacrificial anode rod, which is one of the most overlooked parts for tank longevity.
In the Midlands, anode rods often deteriorate within 3–5 years due to mineral-heavy water conditions. Replacing the rod early can significantly extend your water heater’s lifespan.
Most competitors don’t check this part, even though it’s one of the easiest ways to prevent early tank corrosion.
