6 Signs Your Water Heater Needs Replacing in Dallas
Water heaters do not last forever. The average tank water heater in Dallas lasts 8–12 years, and tankless units last 15–20 years with proper maintenance. Here are six signs that your water heater is reaching the end of its useful life.
1. Age Over 10 Years
If your tank water heater is more than 10 years old, it is in the replacement zone. Check the serial number on the manufacturer’s label for the production date. Even if it is still working, efficiency drops significantly after a decade, and the risk of a catastrophic failure increases.
2. Rusty or Discolored Hot Water
Rust-colored water coming only from your hot water taps indicates the inside of your water heater tank is corroding. Once corrosion starts, it is only a matter of time before the tank develops a leak.
3. Rumbling or Banging Noises
Sediment accumulates at the bottom of the tank over time and hardens. When the burner heats the water, it has to work through this sediment layer, creating rumbling, popping, or banging sounds. This sediment also reduces efficiency and accelerates wear on the tank.
4. Frequent Repairs
If you have called a plumber for water heater repairs more than twice in the past year, the cost of continued repairs will likely exceed the cost of a new installation. Our repair vs. replacement guide can help you decide.
5. Leaking From the Tank
A leak from the body of the tank — not from a fitting or valve — means the tank has corroded through. This cannot be repaired and the unit should be replaced before it fails completely and floods your home.
6. Not Enough Hot Water
If you run out of hot water faster than you used to, sediment buildup may be reducing your tank’s effective capacity, or the heating elements may be failing. In either case, the unit is declining.
