Plumbing systems are an integral component in every commercial and residential building. They are responsible for water distribution to address daily necessities and waste management to prevent contaminated water from flowing back up the drains. Due to its functions, it is crucial to keep your pipes, fixtures, and valves well-maintained by installing an access door panel.

Even though most plumbing materials last long, many are still prone to wear and tear due to a lack of maintenance and regular inspection. One of the most common deteriorations in plumbing pipes is corrosion. Let’s look at some tips from a local plumber on how to prevent pipes from rusting.

What is Corrosion?

When we talk about plumbing, corrosion is the deterioration of the pipe’s metal interior after prolonged exposure to water. The line disintegrates into the water when specific physical and chemical reactions compromise the pipe’s quality, and your system could eventually fail.

Aside from pipe failure, pipe corrosion poses several unfortunate consequences to your household or establishment. Blue staining from copper corrosion can destroy the quality of sinks, tubs, and fixtures and stain your laundry and hair. Corroded pipes will inevitably cause damage to heaters, appliances, and institutions and, in some cases, may make your water unsafe to drink.

What Causes Corrosion in Your Plumbing Pipes?

There are several causes of pipe corrosion, but all of them result in a harmful reaction between your water and piping.

  • pH Levels- If your water has a pH level lower than seven, it is acidic and can prematurely corrode your pipes. You can test your water’s pH levels to see if your lines may be at risk.
  • Oxygen Level- High dissolved oxygen levels can cause your pipes to corrode. Water with a low pH level is typically over-oxygenated. It can easily corrode your lines due to its acidic and highly oxygenated condition.
  • Temperature- The temperature of your water can also increase the likelihood of corrosion. The higher the water temperature, the more rust will form.
  • Chemical Makeup- Minerals in your water can result in corrosion development. For example, calcium and sodium can contribute to increased rust buildup.
  • Velocity- High water velocity relative to the pipe size can also cause corrosion. Corrosion will develop more if the circulating water is under high temperature.
  • Bacteria- Microbiologically influenced corrosion can cause your pipes to fail in just a few years. It is due to microorganisms in your water, like sulfate or iron bacteria.

Tips from a Local Plumber:

Now that we know the significant causes of pipe corrosion, here are some ways on how you can prevent them.

Monitor Your Water

Water is the main culprit of pipe corrosion. Especially in copper piping, a low pH level can damage the pipe’s lining. Furthermore, you should also monitor your water’s oxygen levels since oxygen can lead to rust and cause buildups and blockages. Lastly, it would be best to keep water temperatures low since higher water temperature tends to be more corrosive.

Keep Pipes Clean

When exposed to your pipes, Corrosive bacteria can cause microbiologically induced corrosion. It’s wise to clean pipes to prevent MIC, especially when lines regularly contact sulfides. You can utilize inhibitors or biocides to keep fluids clean. You can also try chemical treatment for water or other liquids.

Keep Plumbing Fixtures Stable

Friction, bouncing, or jiggling can result in the wearing of metal. When openings in your pipes form, corrosive material can get in, which leads to crevice corrosion. An excellent way to prevent crevice corrosion is to use restraint. U-bolts, straps, and clamps minimize vibrations that lead to deterioration.


These essential tips for preventing pipe corrosion can save you from the dangers of using contaminated water. Ensure that you have your plumbing fixtures regularly checked by a trained professional.
