Replacing a water heater can feel like a big task, but at some point, it becomes necessary. In St. Petersburg, FL, we’ve noticed an increasing number of home inspectors recommending water heater replacements, even when the units appear to be functioning. This may be due to insurance companies refusing to cover water heaters over 10 years old, as older units are more prone to leaks and failures.
As a homeowner, understanding when to repair vs. replace your water heater can save you time and money. Here are the key signs to watch for when your water heater is nearing the end of its life.
1. No Hot Water
The most obvious sign of a failing water heater is when it stops producing hot water. This issue often stems from:
- A burned-out heating element (electric models)
- A faulty gas control valve or pilot light (gas models)
- Sediment buildup preventing efficient heating
While some internal parts can be repaired, a water heater over 10 years old typically isn’t worth rebuilding. At Flow Pros Plumbing, we recommend replacement over repair when the unit is past its prime.
💡 Did you know? A full water heater rebuild can cost $650–$850, which could be better invested in a new, energy-efficient unit.
2. Rust or Leaks Around the Unit
If you notice rust at the bottom of your water heater or leaks forming around the unit, it’s time to replace it. Water heater tanks naturally corrode over time, and once rust appears, there’s no repair solution—a replacement is necessary.
🚨 Warning: Small leaks can quickly turn into major water damage. If you see puddles of water near your unit, call Flow Pros Plumbing immediately to prevent costly home repairs.
3. The Age of Your Water Heater
Water heaters typically last 8-12 years. If your unit is over 10 years old, it’s a good idea to plan for a replacement before it fails unexpectedly.
🔎 How to Check Your Water Heater’s Age:
- Look at the information plate on the unit.
- The serial number usually contains the manufacture date.
- If your heater is 6 years old or less, a repair may be a good option.
For units over 10 years old, rebuilding doesn’t always make financial sense. We’ve had customers ask if we can repair a 20-year-old water heater, but at that age, replacement is the only safe and practical choice.
4. Frequent Repairs and Electrical Malfunctions
If you’ve had multiple repairs and are still losing hot water, your water heater may be beyond saving. Watch for these warning signs:
- Soot marks or scorch marks (on gas water heaters)
- Burnt wiring or tripped breakers (on electric models)
- Sediment buildup causing rumbling noises
