Cold water is doing more work than usual
Winter nights in the Bronx average 28°F from December through February, and the water coming into the tank starts out that cold too. Your water heater has to work harder to bring it up to temperature, and it does that seven months of the year, October through April. That extra work falls on the heating element or the burner assembly, and on the thermostat that tells it when to fire.
When one of those parts starts to give out, you notice it fast. Water that never quite gets hot. A pilot that won't stay lit. A tank making noise it didn't used to make.

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 most common cause is the tank itself has corroded through and is failing from the inside. Sediment builds up at the bottom of the tank over years, and it traps water against the steel until it rusts through. Once a tank is leaking this way it needs to be replaced, not patched, since the damage only gets worse. A leak can also come from a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done for.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer tell the gas valve that the pilot is burning, so the valve shuts the gas off. A weak or dirty pilot flame, a draft blowing across it, or a clogged pilot tube can cause the same thing. A thermocouple is a cheap, quick part to replace and fixes most cases like this. If the pilot relights and holds but the burner still won't stay on, the problem is more likely the gas valve itself.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Error codes usually point straight to the cause, whether it's a flow sensor, an igniter, a flame sensor, or buildup on the heat exchanger from hard water. Mineral scale is the most common issue over time, and flushing the unit clears it in most cases. A contractor can pull the error code and diagnose it directly rather than guessing at the cause.
