Water Heater Inspection Issues

Water heater issues are one of the most common inspection findings — and one of the most predictable costs to plan for.

Common Water Heater Findings

  • Age 10+ years: Average tank lifespan: 8–12 years. Budget for replacement soon: $1,200–$2,500
  • Corrosion or rust: Visible rust on tank or connections indicates approaching failure: replacement likely needed
  • Improper venting: Gas water heater venting issues = CO risk. Fix required: $200–$800
  • No expansion tank: Required by current code. Installation: $100–$300
  • Sediment buildup: Reduces efficiency. Flush needed: $100–$200. Preventable with annual maintenance
  • TPR valve issues: Temperature/pressure relief valve missing or improper = safety hazard: $100–$250 fix

Replacement Options & Costs

Standard tank (40–50 gal): $1,200–$2,000. High-efficiency tank: $1,500–$2,500. Tankless: $2,500–$4,500. Heat pump hybrid: $2,000–$3,500. Consider energy savings when choosing — a heat pump model can save $200–$400/year in operating costs.

Negotiation Strategy

Water heaters under 5 years with minor issues: not a negotiation item. 8–12 years old: request $1,000–$1,500 credit for remaining life. Active rust/corrosion/leaking: request full replacement credit ($1,200–$2,500). Safety issues (venting, TPR valve): sellers typically concede immediately.

Cost range

Water heater repair to replacement: $100–$4,500
