When you turn on the hot water faucet, you expect hot water. In fact, you don’t really expect it, you just take it as a given. But if you wait for the water to heat up, and it only gets to “lukewarm,” then you may have a problem with your water heater.
Before we take a closer look at the water heater’s potential troubles, make sure the problem isn’t restricted to only one fixture. If only one fixture is experiencing the issue, the trouble is probably with the mixing valve of that fixture, and you can direct your plumber right to the source of the problem.

Corrosion is a chemical reaction between water and metal in the presence of oxygen, resulting in a weakening of the metal. There are different types of corrosion, but rust is the most familiar. No matter the type, corrosion is straight up bad news for metal because it eats into it and eventually causes it to flake away. (In fact, the word corrosion comes from the Latin word meaning “to gnaw.” Corrosion gnaws away at metal.)
If you have noticed water starting to pool around the base of your storage tank water heater and you’re concerned about it … well, you’re already on the right track! The only place water should be escaping for a hot water tank is a few drips from the temperature and pressure relief valve. Anything else indicates trouble with the water heater. In most cases this will require calling for
