What It Means When Your Water Heater Has a Rusty Bottom

Your water heater works best with regular maintenance from an expert plumber. This annual service gives you the time to notice quickly and fix likely problems. One such issue is a rusty bottom on tank water heaters.

Rust can take root in different places on your water heater and could be the result of damaged connections. But rust on the bottom of your water heater’s tank can be pointing to a more complicated problem. We suggest calling a professional like Donelson Air Service Experts to discover if the tank’s interior liner has corroded. This happens after the anode rod fails. When functioning like it’s supposed to, the anode rod filters impurities from the water.

When your tank has rust, it’s wise to schedule water heater replacement. Otherwise, you risk having your home flooded with gallons of water when the tank gives out.

Here are a small number of other signs that your water heater is on its way out.

4 Clues You Should Schedule Water Heater Replacement

While your water heater can’t share exactly when it’s going to shut down, these are telltale signs that it’s going out.

1. Age

A well-maintained water heater generally lives for about 10 years. If yours is close to this age or older, it’s a wise idea to research replacing it even if it’s still in decent shape. That way, you can avoid not having hot water or a mess if the tank leaks.

2. Rusty Water

This is evidence that your water heater’s tank is corroding. Your water could taste strange or stain your clothes when you wash them. While rust isn’t especially harmful, it affects your water quality and might also stain your bathroom fixtures.

3. Reduced Hot Water

Your water heater should produce enough hot water, even if you’re showering and washing clothes at the same time. If you learn yours is struggling even with low use, it’s time to get a replacement.

4. Strange Sounds

When your water heater’s anode rod malfunctions, sediment collects in the tank. As a result, your water heater must work more intensely to heat water. This can produce clanking or knocking sounds, as well as higher energy bills.

Tankless Water Heaters vs. Tank? What’s Right for My House?

Our experienced plumbers will discuss what’s best for your specific needs and your home. When thinking about hot water heater replacement, they’ll help you pick between tankless water heaters and tank models. Here are a number of the key differences.

Tank Water Heaters

Tank water heaters are the most common model. They have a dedicated supply of hot water, which is tailor-made for heavy or frequent use. While these water heaters are the most affordable, they have some downsides. They are large and constantly heating water, which is less energy efficient. And with a life span of about 12 years, they must be replaced more regularly than a tankless model.

Tankless Water Heaters

Tankless water heaters are prized for their energy efficiency since they heat water when told. Because they don’t have a tank, they can be tucked away in tight spaces, like under your sink or in a closet. As another bonus, they generally last twice as long as a tank model. However, it’s wise to note they’re often more expensive than tank models. But this cost can be balanced with rebates since several models are ENERGY STAR® rated.
