Annual Water Heater Flushing
Sediment settles in tank bottom. Minerals from NWA water. Reduces tank capacity. Reduces efficiency. Causes premature failure. See professional flushing service. How to flush. Shut off power or gas. Let tank cool 30 minutes. Attach hose to drain valve. Run hose to floor drain or outside. Open drain valve, drain 2-3 gallons. Water runs dirty at first, clears as sediment flushes. Close valve when water runs clear. Refill tank, restore power or gas. Annual flushing removes sediment before it hardens. Every-other-year schedule works for some homes. NWA hard water areas need annual.
Anode Rod Inspection Every 3-5 Years
Anode rod is sacrificial component. Corrodes instead of tank. Tank lasts longer. See what anode rod does and why you should care. Check at 5-year mark. Sooner if water heater is over 8 years old. Unscrew rod from tank top. Inspect condition. Rod mostly consumed (less than half-inch diameter). Replace rod. Rod still thick. Reinstall, check again in 2-3 years. New rod costs $20-60. Extends tank life 3-5 years. Preventing $1,500 replacement. Easy ROI.
Temperature Setting Check
Optimal setting 120°F for most homes. Hot enough for comfort and safety. Not so hot it wastes energy or scalds. See temperature setting guide. Higher temperature wastes energy. Every 10°F above 120 adds 3-5% to operating cost. Shorter water heater life from higher temps. Lower temperature risks bacteria. Below 120°F allows bacteria growth. Legionella specifically. Check setting annually. Dial gets bumped. Setting changes without notice.
Pressure Relief Valve Test
Safety valve prevents tank explosion. Opens if pressure or temperature gets too high. Test annually. Lift valve handle briefly. Water should flow from discharge pipe. Release handle. Flow stops. No flow when lifted means valve is stuck. Replace immediately. Valve drips after testing. Sediment got under valve seat. Lift and release again. Usually clears. Still dripping means valve replacement needed.
Visual Inspection
Check for rust or corrosion on tank exterior. Minor surface rust is cosmetic. Rust through tank means replacement coming. Moisture around tank base. Tank leak, fitting leak, or pressure valve discharge. All need diagnosis. Strange noises from tank. Popping or rumbling means sediment buildup. Needs flushing. Hissing or sizzling means water on hot elements. Tank leak possible.
