What Phoenixville winters do to a water heater
Your water heater works harder from October through April, when incoming water runs cold and the tank has to make up more ground to hit temperature. On nights near 25°F, that is a longer burn or a longer heating cycle every time someone runs a shower.
Phoenixville has seen 32 winter storms and 478 damaging wind events over the past ten years, and storms here have knocked out power to homes across Pennsylvania. A gas water heater with a standing pilot keeps working through an outage. One with an electric ignition will not fire until power is back, so you may find the water cold after the lights come on.

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. Water heaters corrode from the inside over years, and once the tank wall gives way, water finds the weakest point and seeps out the bottom. It can also be a loose drain valve or a fitting on the bottom of the tank, which a contractor can tighten or replace. But if the tank itself is cracked, the unit needs to be replaced, not repaired, since there's no way to patch a leaking tank.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer sensing that the pilot is lit, so it shuts off the gas as a safety measure. A dirty or clogged pilot orifice can cause the same problem by starving the flame. Sometimes a draft from a nearby vent or door blows the pilot out before the thermocouple even gets involved. A contractor can test the thermocouple and clean or replace the parts that are failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or a bad flow sensor can all be fixed without replacing the unit. Tankless units also run diagnostic codes, so a contractor can usually pinpoint the failing part quickly. Replacement only becomes necessary if the heat exchanger itself has cracked or corroded through.
