FAQs
Why is flushing sediment important for a tank water heater in Chattanooga?
Chattanooga’s municipal water supply is classified as moderately hard, meaning it carries dissolved calcium, magnesium, and trace minerals. When this water is heated, those minerals precipitate out and sink to the bottom of your tank, forming a layer of sediment. That layer acts like an insulator between the burner (or heating element) and the water, forcing the appliance to run longer, use more energy, and work under higher temperatures that can warp the tank lining. Regular flushing removes this sediment, restoring efficiency, extending the life of the anode rod and tank, and reducing the risk of scalding or rumbling noises.
How often should I flush my tank water heater in the Chattanooga area?
Most manufacturers recommend annual flushing, but in the Chattanooga area we generally suggest every 9–12 months if you have untreated city or well water. Homes with a whole-house water softener can usually stretch the interval to 18–24 months because the softener captures many of the hardness minerals before they reach the heater. If you notice cloudy tap water, popping noises, or slower recovery times, schedule a flush sooner.
What are the warning signs that my water heater has sediment build-up?
• Rumbling, popping, or knocking sounds when the burner ignites • Hot water that runs out faster than it used to • Longer recovery times between showers or loads of laundry • Higher-than-normal energy bills without any change in usage • Cloudy or slightly brown hot water at the tap • Temperature fluctuations (hot bursts followed by lukewarm water) If you experience one or more of these, sediment is likely the culprit and a professional flush is recommended.
Can I flush the tank myself or should I hire a professional plumber?
A handy homeowner can perform a basic flush by turning off the gas or power, shutting the cold-water valve, attaching a hose to the drain valve, and emptying the tank until the water runs clear. However, professionals: 1. Inspect the anode rod, T&P valve, and gas/vent connections. 2. Use high-flow pumps or descaling solutions when sediment is stubborn. 3. Safely relight gas burners and verify proper combustion. 4. Haul away or recycle old parts. If your heater is under warranty, professional service also keeps the warranty intact. If you’re unsure—or if the drain valve is clogged—call a licensed Chattanooga plumber.
Will flushing my water heater lower my energy bills?
Yes. The U.S. Department of Energy estimates that just ½ inch of sediment can increase energy consumption by 15–20 %. By restoring direct contact between the burner or element and the water, a flush allows the thermostat to reach set temperature faster and cycle off sooner. Chattanooga homeowners typically see utility savings of $3–$7 per month on natural gas and up to $10 on electric models, depending on usage.
How long does a professional water heater flush take and will it interrupt my water supply?
A standard flush on a 40- or 50-gallon tank takes 45–60 minutes, including setup, draining, sediment agitation, refill, relighting, and safety checks. During that time the hot water supply is off, but cold water remains available. Larger 75- or 100-gallon commercial tanks may require up to two hours. Once the unit is refilled and reheated—usually another 30–45 minutes—you’ll have normal hot water service.
