Miami-Dade's water heaters work year round with no break
Your water heater doesn't get a season off here. Homes in this county need zero months of heat a year, so the tank runs the same load in every month, with no slow stretch to ease the wear on the anode rod and the heating element.
Storms bring another problem. Miami-Dade has had 80 damaging wind events over the past ten years, and statewide, 38% of households lost power for 24 hours or more in 2024. Most tank water heaters come back on by themselves once power returns, but a gas unit with a pilot light will not relight on its own, and you will notice cold water until it does.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The tank itself has likely corroded through and is leaking water it can no longer hold. Water heaters rust from the inside as the glass lining wears down over the years, and once the steel underneath is exposed, it gives way. A loose drain valve or a fitting at the bottom can also leak and look like the tank itself is failing. A contractor can check the valve and connections first, but if the tank is rusted through, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and can no longer sense that the pilot is burning, so it shuts the gas off. A draft blowing across the pilot, a dirty pilot orifice, or a bad gas control valve can cause the same thing. A standing pilot runs without power, so this isn't an electrical issue. A contractor can test the thermocouple and valve to find which part is failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, a clogged inlet filter, and sensor errors are all common issues a contractor can fix without replacing the unit. If the heat exchanger itself has cracked or corroded, replacing that part, or the unit, may be the only option.
