Cold groundwater keeps your water heater working longer
Winter nights in La Plata average 29°F from December through February, and that cold reaches the water line coming into your house. Your water heater has to work harder to bring that colder water up to temperature, and it does this for seven months of the year, October through April. The burner or heating element runs longer and more often to keep up.
That extra run time wears on the parts that do the heating. A gas water heater's burner and igniter cycle more often, and an electric unit's heating element stays under load longer. You may notice the water taking longer to get hot, or running out faster than it used to. Power loss is also a factor here. Maryland households saw outages of 24 hours or more in 2024, and most water heaters need a working thermostat or control board to fire back up once power returns.

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 from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years and traps moisture against the steel, and once it wears through, no fitting or valve fix stops the leak. It can also be the drain valve or a fitting that has loosened, which a contractor can check before assuming the tank is done. If water is pooling under the tank itself rather than around a pipe connection, plan on replacing the water heater.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and no longer signals the gas valve to stay open. The thermocouple sits in the pilot flame and tells the valve it is safe to keep supplying gas. When it wears out or sits out of position, the valve shuts the gas off as soon as you let go of the knob. A dirty pilot orifice or a draft blowing the flame around can cause the same thing, so a contractor needs to look at the actual pilot assembly to tell which one it is.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Error codes usually point to a specific part, like the igniter, the flow sensor, or a blocked vent, and a contractor can replace that part rather than the whole unit. Mineral buildup on the heat exchanger is common too and is cleared with a descaling flush rather than a replacement. A contractor can tell you whether what you're seeing is a simple fix or something that points to a bigger problem with the unit.
