Why Water Heater Maintenance Matters

- Improves efficiency – A well-maintained water heater uses less energy, lowering monthly bills.

- Keeps warranties valid – Many manufacturers require proof of routine maintenance.
How Often Should You Service Your Water Heater?
Annual Service Is Best
For most homeowners in Houston and surrounding areas, servicing your water heater once a year is the sweet spot. This applies to both traditional tank water heaters and tankless systems. An annual service typically includes:
- Flushing the tank to remove sediment buildup
- Inspecting the anode rod (to prevent rust)
- Checking the thermostat and heating elements
- Testing the temperature & pressure relief valve for safety
- Inspecting for leaks or corrosion
When You May Need Service Every 6 Months
- You have hard water (common in Houston).
- Your family uses a lot of hot water daily.
- You notice reduced performance (slow heating, temperature swings, or unusual noises).
Signs Your Water Heater Needs Immediate Attention
- Rust-colored water – Could indicate corrosion inside the tank.
- Popping or rumbling noises – Often caused by heavy sediment buildup.
- Inconsistent water temperatures – Possible thermostat or heating element issues.
- Water pooling around the unit – Potential leaks or pressure problems.
- Low hot water supply – The tank may not be operating at full capacity.
- Rotten Egg Smell — Could indicate the need for anode replacement
Tank vs. Tankless Water Heater Service
Tank Water Heaters

- Anode rod inspection is critical (replace every 3–5 years).
- Typical life expectancy: 8–12 years with proper care.
Tankless Water Heaters

Homeowner Tips Between Maintenance Services
