Flush the tank, inspect the anode rod, check the temperature setting, and schedule regular inspections to maintain your water heater for longevity. A well-maintained unit in Spokane, Washington can last over 12 years, while neglected systems fail much sooner.
Proper maintenance reduces energy bills, prevents leaks, and improves hot water reliability. This guide covers specific steps, tools, and timelines to help extend the life of your water heater in Spokane homes.
Types of Water Heaters and Their Lifespan
| Type | Average Lifespan |
|---|---|
| Gas Storage Tank | 8–12 years |
| Electric Storage Tank | 10–15 years |
| Tankless (On-Demand) | 15–20 years |
| Hybrid (Heat Pump) | 10–15 years |
Tankless systems last longer but still need regular care. You can learn more about tankless water heaters and if they're right for your home.
Ways to Maintain Your Water Heater for Longevity
Flush the Water Heater Tank Annually
Sediment buildup from hard water reduces efficiency and shortens unit life. Flushing removes this debris.
Steps to Flush the Tank
- Turn off the power or gas supply
- Connect a garden hose to the drain valve
- Open the valve and let the water drain completely
- Close the valve, refill, and restore power
For Spokane homes with high mineral content, flush every 6–12 months. If unsure how to proceed, contact our water heater repair experts for help.
Check the Anode Rod Every 2–3 Years
Anode rods prevent tank rust by attracting corrosion. Once the rod is worn, your tank becomes vulnerable.
How to Inspect and Replace the Rod
- Shut off the power and water supply
- Drain a few gallons from the tank
- Unscrew the rod on top of the heater
- Replace if less than 1/2 inch thick or heavily corroded
Use magnesium rods for hard water areas like Spokane.
Adjust the Thermostat to 120°F
High temperatures cause overheating and stress. Keep the thermostat at 120°F to lower wear and save energy.
Every 10°F reduction cuts energy use by 3–5%. This also reduces the risk of scalding.
Inspect for Leaks and Corrosion
Monthly checks help spot early signs of failure.
Look for:
- Pooled water around the base
- Rust spots or streaks
- Drips from pipe connections
- Discoloration on the pressure relief valve
If you notice any of these, consider calling for water heater repair or replacement in Spokane, Washington.
Test the Temperature and Pressure Relief Valve (T&P Valve)
This safety valve prevents tank pressure buildup. It should release a burst of water when lifted.
How to Test It:
- Place a bucket under the discharge pipe
- Lift the valve lever
- Water should flow briefly, then stop
- Replace the valve if no water flows or it leaks afterwards
Insulate Older Water Heaters and Pipes
Insulating blankets reduce heat loss by 25% for older models. Use pipe sleeves on exposed hot water lines to retain heat.
Don't cover the thermostat or burner compartment. In Spokane's cold winters, insulation keeps water hot longer and lowers bills.
Schedule Annual Professional Inspections
Yearly inspections catch hidden issues early. A licensed plumber can:
- Check burner or element condition
- Test the thermostat and T&P valve
- Inspect the anode rod
- Flush and clean the tank
If your unit is aging or showing signs of wear, explore options for a hot water dispenser or tankless upgrade.
Don’t Ignore Unusual Noises or Discolored Water
Popping sounds may indicate sediment buildup. Rust-colored water means internal corrosion.
Act quickly if you notice:
- Loud rumbling or popping
- Cloudy or rusty hot water
- Water takes longer to heat
These signs mean you may need emergency water heater service to prevent a complete breakdown.
How to Maintain Tankless Systems in Spokane Homes
Tankless units need descaling to remove mineral buildup.
How to Descale a Tankless Unit
- Turn off the power and water supply
- Connect a pump and hose loop with vinegar
- Circulate for 45 minutes
- Flush with clean water
If uncomfortable performing this task, call commercial water heater experts for assistance.
When to Replace Your Water Heater
Even with maintenance, water heaters don’t last forever. Signs you may need a new unit:
- The unit is over 10 years old
- Frequent breakdowns or repairs
- High energy bills
- Visible corrosion or rust
- Hot water runs out quickly
Our plumbers in Spokane can help with residential and commercial replacement options.
