We recommend an annual sediment flush for conventional storage tanks in Belfast, ME, especially in regions with hard municipal water. Tankless systems should also receive a descaling flush every 12 to 18 months.
If your water heater is under 10 years old and the problem involves a replaceable component—such as an electrical element, thermostat, gas valve, or thermocouple—a repair is usually the most cost-effective route.
