FAQs
How long does a traditional tank water heater typically last in Charleston’s climate?
With Charleston’s warm, humid coastal climate and moderately hard water, most tank-style water heaters last 8–12 years. Regular flushing, anode-rod inspection, and proper expansion-tank installation can help you reach the upper end of that range. If your heater is more than 10 years old, budget for replacement to avoid an unexpected leak.
What tank size is right for my household?
A good rule of thumb is 40 gallons for 1–2 people, 50 gallons for 3–4 people, and 66–80 gallons for 5 or more. However, lifestyle matters: large soaking tubs, frequent laundry, or simultaneous showers may require upsizing. Our technicians perform a usage audit—factoring in fixture flow rates and peak-hour demand—to recommend a tank that provides steady hot water without wasting energy.
Do I need a permit to replace a water heater in Charleston?
Yes. The City of Charleston and surrounding municipalities require a plumbing permit for any water heater replacement. A licensed plumber pulls the permit, schedules an inspection, and documents that the installation meets South Carolina Plumbing Code, including seismic strapping, drain-pan routing, and proper temperature-pressure relief (TPR) valve discharge.
How often should I flush my tank water heater?
Charleston’s water contains minerals that form scale on the tank bottom and heating elements. Flushing 1–2 times per year removes sediment, improves efficiency, and reduces rumbling noises. We attach a hose to the drain valve, power down the unit, and purge a few gallons until the water runs clear. Annual anode-rod checks during the same visit help prevent internal corrosion.
What are common warning signs that my tank water heater is failing?
• Rust-colored or metallic-tasting hot water • Popping or crackling sounds (sediment buildup) • Moisture, rust, or pooling water around the base • Inconsistent water temperature or recovery times • Visible corrosion on inlet/outlet fittings or TPR valve • Pilot light that won’t stay lit (for gas models) Addressing these early can sometimes extend the unit’s life or avoid water damage from a sudden tank rupture.
Can I improve efficiency without replacing the entire unit?
Yes. Adding an insulation blanket (if the tank’s R-value is below 24), insulating hot-water pipes, lowering the thermostat to 120 °F, and installing a timer or smart controller on electric models can cut energy use 5–15 %. Replacing a worn anode rod and flushing sediment also boosts efficiency. For bigger savings, consider a heat-pump hybrid or tankless upgrade; Charleston’s mild climate is ideal for these high-efficiency options.
