Expert tips from licensed Tulsa metro plumbers. Learn when to flush, how to inspect your anode rod, and the signs that mean it's time for repair or replacement.
Everything you need to know about maintaining your water heater — in order.
Regular maintenance takes 30-60 minutes and can add years to your water heater's life. Tulsa's hard water makes this especially important.
Drain and flush the tank to remove sediment buildup. This is the single most important maintenance task for tank water heaters. In Tulsa's hard water, twice a year is better.
Annually (or every 6 months in Tulsa)The sacrificial anode rod prevents tank corrosion by attracting minerals instead of your tank walls. Check it every 2-3 years; replace if worn down to half its original size or coated in calcium.
Every 2-3 YearsThe temperature and pressure relief valve is your water heater's safety device. Test it annually by lifting the lever — water should flow freely out of the discharge pipe. If it doesn't, replace it immediately.
AnnuallySet your thermostat to 120°F. Below 120°F risks Legionella bacteria growth; above 125°F significantly increases scalding risk. Tulsa's ambient temperatures make this check especially important seasonally.
AnnuallyLook for rust spots on the tank exterior, moisture or pooling around the base, corrosion on pipe fittings, and check that the discharge pipe is intact and unobstructed. Any of these warrants professional attention.
AnnuallyCheck all gas connections for leaks with soapy water (bubbles = leak). Inspect the venting system for obstructions, gaps, or deterioration. A damaged vent can allow carbon monoxide into your home — never skip this.
AnnuallyTankless units don't have a tank to flush, but they do accumulate mineral scale on the heat exchangers. Annual descaling is essential — especially in Tulsa's hard water — to maintain efficiency and prevent premature failure.
Switch off the breaker and turn the gas valve to pilot. Allow the unit to cool for 15 minutes.
Connect a submersible pump to the cold water inlet using a barrel of white vinegar or a commercial descaling solution.
Run the pump so solution flows through the heat exchangers and out the hot water outlet. Repeat on reverse flow.
Run fresh water through both paths until the discharge runs clear. Restore power and gas, then test for proper operation.

Step-by-step guide for standard tank water heaters. Estimated time: 45 minutes.
Flip the breaker or set gas to PILOT. Never skip this.
Close the cold water inlet valve at the top of the tank.
Run a hot water faucet in your home to release tank pressure.
Connect hose to the drain valve. Run to a floor drain or outside.
Open the drain and let tank fully empty. Flush until water runs clear.
Close drain, turn on cold water, wait for faucet to run clear, then close it.
Turn breaker back on or set gas to ON. Check for leaks within 30 minutes.
Estimated total time: 45 minutes | Difficulty: Moderate | Tools needed: Garden hose, adjustable wrench
Know the difference between issues you can monitor and problems that need immediate attention.
Any pooling water around the base of your water heater is a serious problem. It likely means the tank itself has corroded through. Once a tank starts leaking internally, repair is not an option — replacement is the only solution. Don't wait for a flood.
Emergency service available →Brown or rust-colored water coming from hot taps means the inside of your tank is corroding. The anode rod has likely failed. This typically means the tank wall is compromised and replacement is needed. Flush immediately and call us for an assessment.
Schedule assessment →These noises indicate heavy sediment buildup at the bottom of the tank. The sediment traps water and causes it to overheat and "pop" as it flashes to steam. Flush the tank first — if noises persist after a flush, the tank may be too damaged to save.
Schedule a flush →A rotten egg smell from hot water usually means bacteria has built up in the tank — often after periods of disuse. Try running hot water for several minutes to flush the system. If it persists, the anode rod may need replacement or the tank may need sanitizing.
Get a diagnosis →Could be a failed heating element (electric), thermocouple or gas valve issue (gas), or a oversized unit undersized for your household. First try resetting the breaker. If it trips again or the problem recurs, schedule a diagnostic — do not keep resetting the breaker.
See repair options →Slow heating usually means sediment buildup insulating the heating elements, a failing thermostat, or a damaged dip tube. If flushing doesn't restore normal heating times, one of these components needs professional replacement. Age of the unit matters here.

The short answer: tank units last 8-12 years, tankless last 15-20 years. But your mileage varies.
