FAQs
Why should I have my tank water heater flushed every year in Dandridge?
Mineral-rich water in the Dandridge area causes sediment to build up quickly inside conventional tank water heaters. An annual flush removes this buildup, restoring efficiency, extending the life of the tank and burner elements, and reducing the risk of scalding temperature fluctuations or premature leaks. Regular flushing also keeps your manufacturerâs warranty valid, as many brands require documented maintenance.
What exactly is included in an annual water-heater flush service?
Our licensed technicians will (1) shut off gas or electricity to the heater, (2) close the cold-water supply and attach a drain hose, (3) fully drain the tank to remove sediment, (4) rinse the interior with fresh water until it runs clear, (5) inspect the anode rod and temperature-pressure relief valve, (6) relight or re-energize the unit, and (7) verify proper operation and safety settings. We finish with a written report and maintenance tips specific to your homeâs water quality.
How long does a professional flush take?
A standard flush on a residential 30â50-gallon tank in Dandridge typically takes 45â60 minutes from shut-down to restart. Allow a little extra time if heavy sediment requires multiple rinses or if we replace the anode rod or T&P valve during the same visit.
Are there signs I need a flush sooner than once a year?
Yes. Rumbling or popping noises when the burner fires, rusty or cloudy hot water, slower hot-water recovery, or higher energy bills can all indicate excessive sediment. If you notice these symptomsâespecially in hard-water zones east of Douglas Lakeâschedule a flush right away rather than waiting for your annual service date.
Will flushing harm my older gas or electric tank?
No. When done by a trained professional, flushing is safe for both gas and electric models, regardless of age. Controlled draining and refill procedures prevent thermal shock, and component inspections help us spot issues before they cause leaks. In fact, older heaters benefit most because sediment accumulation accelerates with age.
How much does the service cost and how do I schedule it?
In Dandridge, our flat-rate price for a standard annual tank flush starts at $129, which includes sediment removal, safety checks, and a written tune-up report. Any optional parts (anode rod, T&P valve) are quoted before installation. Call our office or book online 24/7; most appointments are available within 2â3 business days, and same-day emergency flushes are offered when capacity allows.
