What Rust Underneath Your Water Heater Means

Your water heater works best with consistent maintenance from an experienced plumber. This annual service gives you the opportunity to notice quickly and take care of likely problems. One such issue is a rusty bottom on tank water heaters.

Rust can form in several places on your water heater and can be the result of loose connections. But rust on the bottom of your water heater’s tank may be evidence of a more complex problem. We recommend calling a professional like Strand Brothers Service Experts to discover if the tank’s interior liner has rusted. This occurs after the anode rod fails. When working normally, the anode rod removes impurities from the water.

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

Here are several other signs that your water heater is breaking down.

4 Signs You Should Schedule Water Heater Replacement

While your water heater can’t inform you exactly when it’s going to fail, these are common signs that it’s going out.

1. Age

A well-maintained water heater typically survives for close to 10 years. If yours is near this age or older, it’s a good idea to research replacing it even if it’s still running. 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 rusting. Your water could taste unpleasant or stain your clothes when you wash them. While rust isn’t always harmful, it affects your water quality and can also stain your bathroom fixtures.

3. Less Hot Water

Your water heater should provide a steady supply of hot water, even if you’re showering and washing clothes at the same time. If you discover yours is struggling even with minimal use, it’s time to get a replacement.

4. Abnormal Sounds

When your water heater’s anode rod fails, sediment builds up in the tank. As a result, your water heater must work more intensely to heat water. This can result in banging or knocking sounds, as well as larger energy bills.

Tankless Water Heaters vs. Tank? What’s Ideal for My Residence?

Our well-trained plumbers will share what’s best for your specific needs and your home. When looking into hot water heater replacement, they’ll help you decide between tankless water heaters and tank models. Here are some 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 better-suited 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 much sooner than a tankless model.

Tankless Water Heaters

Tankless water heaters are prized for their energy efficiency since they heat water when told. Because they are without a tank, they can be tucked away in convenient spaces, like under your sink or in a closet. As another bonus, they typically last twice as long as a tank model. However, it’s important to note they’re frequently more expensive than tank models. But this cost can be replenished with rebates since quite a few models are ENERGY STAR® rated.
