Rumbling, popping, or banging noises usually indicate mineral scale and sediment accumulation inside the bottom of the tank. As water gets trapped beneath sediment, steam bubbles form and burst loudly. A professional sediment flush by Water Heater Repair Guy in DeKalb, IL clears this buildup and restores quiet operation.
Traditional storage tank water heaters generally last between 8 and 12 years with routine annual maintenance. Tankless systems can last 20 years or longer when properly descaled and serviced regularly.
We recommend an annual sediment flush for conventional storage tanks in DeKalb, IL, especially in regions with hard municipal water. Tankless systems should also receive a descaling flush every 12 to 18 months.
