What to Do When Your Water Heater is Rusted Underneath

Your water heater runs best with consistent maintenance from an experienced plumber. This annual service gives you the chance to notice quickly and fix possible problems. One such issue is a rusty bottom on tank water heaters

Rust can grow in several places on your water heater and might be the result of damaged connections. But rust on the bottom of your water heater’s tank could be pointing to a more complex problem. We recommend calling a professional like Service Experts Heating, Air Conditioning & Plumbing to discover if the tank’s interior liner has rusted. This happens after the anode rod fails. When working like it’s supposed to, the anode rod removes impurities from the water. 

When your tank has rusted, it’s time to schedule water heater replacement. Otherwise, you risk having your home flooded with gallons of water when the tank breaks. 

Here are some other signs that your water heater is on its way out. 

4 Signs You Need Water Heater Replacement 

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

1. Age 

A well-maintained water heater usually lasts for around 10 years. If yours is close to this age or older, it’s a good idea to look into replacing it even if it’s still in decent shape. That way, you can avoid losing out on 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 might taste strange or stain your clothes when you wash them. While rust isn’t especially harmful, it affects your water quality and may also stain your bathroom fixtures. 

3. Decreased Hot Water 

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

4. Odd Sounds 

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

Tankless Water Heaters vs. Tank? What’s Best for My Home? 

Our well-trained plumbers will recommend what’s best for your specific needs and your home. When considering 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 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 lack a tank, they can be squeezed in smaller 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 frequently more expensive than tank models. But this cost can be offset by rebates since quite a few models are ENERGY STAR® rated.
