The Essential Guide to Water Heater Corrosion

November 29, 2023

Wherever water and metal mix, there’s a risk of corrosion. While water heater manufacturers have developed ways to minimize it, it’s good to know what to look for and what to do if corrosion happens to your unit. Our guide to water heater corrosion has everything you need to know about this common type of plumbing problem!

Water Corrosion Defined

Water corrosion is the process by which a refined metal begins to oxidize due to chemical interactions with its environment (water chemistry and temperature). 

Even the purest tap water contains minerals that interact with the metals in your water heater, which is accelerated by heat. Oxygen and pH levels can also increase the rate of corrosion.

How To Know if You Have Water Heater Corrosion

The biggest red flag you’ll notice if you have water heater corrosion is a rust-colored tint to your water when you run it hot.

However, you may also notice leaks around your water heater, an odd sound coming from your plumbing system, or your water not heating up adequately. All of these symptoms indicate that corrosion has begun to impact the way your water heater is running.

Why Corrosion Is A Water Heater Repair Problem

Corrosion is a serious issue that warrants immediate plumbing repairs. On top of contaminated water and poor heating output, unchecked water heater corrosion can damage your unit to the point that it needs to be replaced entirely. 

Water heaters are no small investment, so promptly taking care of corrosion is essential to prevent minor plumbing repairs from turning into a major expense.

What Your Local Plumber Can Do 

The first thing your plumber will advise you to do about corrosion is take action that will prevent further damage. Regular plumbing maintenance, like flushing your tank to remove the sediment buildup, will make a massive difference in oxidization!

The next step in the water heater repair process is to assess how much corrosion has occurred inside and outside your unit. Based on the structural damage, your plumber will advise whether you should clean and repair affected components or replace your water heater altogether.
