How to Tell When It’s Time to Replace Your Water Heater
Serving Norwalk and surrounding communities since 1958
Hot water is one of those things you don’t think about until it’s gone. If your showers are suddenly cold or your tank makes strange noises, it may be time to replace your water heater. Knowing the warning signs early can prevent costly damage and keep your home running smoothly.
1. Your Water Heater Is Over 10 Years Old
Most water heaters last between 8 and 12 years. If yours is approaching or past that range, it’s smart to start planning for replacement—especially if you notice declining performance. Check the serial number on your tank for the manufacture date (usually printed on the top label).
2. You’re Running Out of Hot Water Faster
If your showers turn cold quickly, sediment buildup inside the tank could be reducing efficiency. As minerals collect at the bottom, they insulate the water from the heating element. Flushing the tank can help temporarily, but if the problem returns, replacement is often the best long-term solution.
3. Rusty or Discolored Water
Rust-colored water from your hot taps is a sign the tank is corroding from the inside. Once rust appears, leaks are usually not far behind. Replacement is the only fix, as corrosion spreads quickly once it begins.
4. Strange Noises or Rumbling Sounds
Banging or popping noises indicate excessive sediment buildup. These hardened layers of mineral deposits make the heater work harder, wasting energy and accelerating wear. Persistent rumbling means the heater is nearing the end of its life.
5. Water Leaks Around the Base
Any moisture or pooling water around the tank is a clear red flag. Even small leaks can cause significant damage to floors and drywall. In nearly every case, a leaking tank should be replaced immediately for safety and efficiency.
6. Rising Utility Bills
Aging water heaters lose efficiency over time. If your energy or gas bills have been creeping up without any change in usage, your heater might be using more power to maintain the same temperature.
7. Considering an Upgrade? Tank vs. Tankless
Modern tankless water heaters offer unlimited hot water and lower long-term operating costs. While the upfront cost is higher, they can last up to 20 years and free up valuable storage space. For homes with frequent hot-water use, they’re a smart upgrade.
Average Cost and Timing in Norwalk
For most Norwalk homes, replacing a standard 40–50 gallon tank costs between $1,400 and $2,200, including installation. Tankless models typically range from $3,000 to $4,500. Professional installation usually takes one day, including disposal of the old unit.
When to Call a Professional
If you notice any of the warning signs above, it’s best to schedule an inspection before the heater fails completely. A licensed Norwalk plumber can assess whether repair or replacement is more cost-effective and help you choose the right model for your home’s needs.
