What Portsmouth winters do to your water heater
Your water heater works harder from November through April, when incoming water runs cold and the tank has to make up more ground before it reaches the tap. On nights that average 35°F, that six-month stretch adds up.
Storms here bring the other risk. Portsmouth has seen 22 damaging wind events and 6 winter storms over the past ten years, and Virginia households lost power for a day or more at a high rate in 2024. When power drops, an electric water heater stops heating until it comes back, and most units pick up again on their own. A gas water heater with a standing pilot keeps running through the outage. Either way, a cold snap paired with a power loss is when a weak heating element or an aging thermostat tends to show itself, right when you need hot water most.

- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through and is starting to fail. Water heaters corrode from the inside as the glass lining wears down, and once the steel tank underneath is exposed, it rusts and eventually leaks. Loose drain valves or fittings can also drip and look like a tank leak, so it's worth checking those first. A tank that's actually leaking from the bottom needs to be replaced, not repaired, since there's no way to patch a hole in the steel.
- Why won't the pilot light on my water heater stay lit?
- A weak or dirty thermocouple is the most common reason a pilot won't stay lit. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. If it's worn out or coated in soot, it can't hold that signal, and the gas valve shuts the pilot off as a safety measure. A dirty pilot orifice or a draft near the burner can cause the same thing, so a contractor will check those before replacing parts.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and causes error codes, reduced flow, or water that won't get hot, and it's typically cleared with a descaling flush. Igniters, flow sensors, and venting issues can also be replaced or corrected without swapping the whole unit. A contractor can pull the error code from the display and tell you whether it's a repair or something serious enough to warrant replacement.
