No Hot Water
Going without hot water rarely fixes itself overnight, so call and get a plumber looking at the tank today.
When this becomes an emergency
- Water that starts warm then turns cold within a minute or two.
- A pilot light that won't stay lit no matter how many times it's relit.
- Rust-colored water coming only from the hot tap.
What a pro does
No hot water has a short list of usual suspects, and the plumber works through them in order. On a gas unit, that starts with the pilot light, the thermocouple, and the gas valve, since a pilot that won't hold usually means one of those has failed. On an electric unit, it's the heating elements and the thermostat instead. The tech also checks tank size against household demand, because a family that's grown since the water heater went in sometimes just runs out of hot water before everyone's done with it. Sediment buildup at the bottom of an older tank can mimic a failing element too.
