Water Heater Guide
Annual flush + age check = no flood disasters.
Know your water heater
- Find install date — sticker or take photo of nameplate.
- Average lifespan 8-12 years.
- Replace BEFORE failing (proactive saves flood damage).
- Tank, tankless, hybrid, electric, gas — different needs.
- Photo nameplate now — needed if emergency replacement.
Annual maintenance
- Flush sediment yearly — extends life 5+ years.
- Check anode rod every 3 years (sacrificial part).
- Test pressure relief valve yearly.
- Check for leaks at pipe joints monthly.
- Set temperature 120°F (saves energy + scald protection).
- YouTube videos show flush DIY ($0).
- Or hire plumber annually $100-150.
Leak prevention (essential)
- Drip pan under heater — catches small leaks.
- Smart leak detector ($30-150) — alerts phone.
- Auto shutoff valve — closes if leak detected ($200-600 install).
- Tank failures = $5K-15K floods.
- Insurance often won't cover if known issue.
- Smart shutoff = best investment.
When to replace
- Age 10+ years — start planning.
- Rust in hot water.
- Strange noises (popping, rumbling).
- Lukewarm water (not hot).
- Visible rust on tank.
- Wet area around base.
- $1,500-3,500 typical replacement.
- Tankless: $3,500-7,000 but lasts 20+ years.
Tankless pros + cons
- Pros — endless hot water, lasts 2x, smaller, more energy efficient.
- Cons — higher upfront cost, may need gas line upgrade.
- 2026 tax credits — heat pump water heaters $2,000+.
- Gas tankless great if gas line existing.
- Hybrid heat pump = greenest option.
