Bowie winters put your water heater to work
From October through April your water heater is heating groundwater that starts out cold, and on nights near 28°F it runs longer to make up the difference. The heating element or burner cycles more to keep up, and that extra work is what wears out a thermostat or igniter years before it should.
Power is part of it too. Maryland saw 11% of households lose power for a full day or more in 2024, and Prince George's County has logged 222 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage, but an electric one or one with an igniter will not restart on its own. If your water comes back cold after the power does, that is why.

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 reason is that the tank itself has rusted through and is failing. Sediment builds up at the bottom of the tank over years, and it traps moisture against the steel until it wears a hole. A leak can also come from a loose drain valve or a fitting that has worked itself loose, and those can sometimes be tightened or replaced. Once the tank is actually cracked or rusted through, though, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Usually a weak or failing thermocouple is the cause. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep sending gas. When it wears out, it can't hold that signal, so the valve shuts the gas off and the pilot goes out. A dirty pilot orifice or a draft hitting the flame can also blow it out. A contractor can test the thermocouple and replace it if it's the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit can be repaired without replacing the whole thing. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter, and each of those can be cleaned or swapped out on its own. The electronic control board can also fail and be replaced separately. A contractor can run the unit's diagnostics to find out which part is causing the problem.
