Delaware County makes a water heater work most of the year
Groundwater coming into your house runs cold from October through May here, eight months of the year. Your water heater has to work harder for longer to get it to a usable temperature, and that extra runtime wears on the heating element and the thermostat that controls it. You notice it as water that takes longer to get hot, or that doesn't get as hot as it used to.
Power loss is the other thing to plan for. Ohio saw 18% of households lose power for 24 hours or more in 2024, and this county has logged 94 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with an electric igniter or an electric unit will not, and it needs to come back on once the power does. If yours doesn't restart on its own, that's worth a look.

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 failing from the inside out. Sediment builds up at the bottom of the tank over years, and it traps water against the steel until the metal rusts through. Once the tank is leaking that way, it can't be patched or sealed, it needs to be replaced. A leak can also come from a loose drain valve or a fitting at the bottom, and those a contractor can often repair without replacing the whole unit. Shut off the water and power to the tank until someone can look at it.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and is no longer telling the gas valve that the pilot is lit. When that happens, the valve shuts the gas off as a safety measure, even though the flame was fine. A dirty pilot orifice or a draft near the pilot can cause the same problem. Either way, this is a gas valve issue, not something to keep relighting on your own.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be fixed without replacing the unit. Mineral buildup on the heat exchanger is common and is cleared by flushing the system. Igniters, flow sensors, and venting issues are also repairable parts. A contractor can test the unit and tell you whether the problem is a part or the exchanger itself.
