Water Heater Replacement

Signs You Need a New Water Heater
- Age — if your water heater is over 10 years old, efficiency has likely declined significantly.
- Rusty water — discolored hot water indicates internal tank corrosion.
- Leaking — any pooling water around the base means the tank is failing.
- Inconsistent heating — fluctuating water temperatures signal heating element issues.
- Strange noises — rumbling or popping sounds indicate sediment buildup.
- Higher energy bills — declining efficiency means your unit is working harder.
- Frequent repairs — regular repairs mean replacement is more cost-effective.
Maintenance Tips
Flush annually
Drain and flush your tank water heater to remove sediment that reduces efficiency.
Check the anode rod
Inspect every 2–3 years. Replace when significantly corroded.
Test the T&P valve
Test the temperature and pressure relief valve annually for safety.
Insulate the tank
An insulation blanket can reduce heat loss by 25–45%.
Descale tankless units
Descale with vinegar every 12–18 months for peak performance.
💡 Pro Tip
When repiping your home, it’s the ideal time to upgrade your water heater. New pipes paired with a modern water heater deliver the best possible performance.
