FAQs About Home Plumbing and Pipe Corrosion

What is pipe corrosion, how can it affect your home's plumbing system, and what can you do to correct this common problem? Take a look at what homeowners need to know about pipe corrosion, repiping, and professional plumbing services.

Why Do Pipes Corrode?

Water, electricity, and oxygen can cause and accelerate pipe corrosion. More specifically, pH imbalances in water, oxidation, hard water, and what that flows at high speeds are all possible causes of pipe corrosion.

Even though electron exchange between pipe metal and other substances is the usual cause of corrosion, it's possible this problem can result from other issues. Misuse of chemical drain cleaners and other similar harsh or acidic chemical products can cause corrosion. These products can eat away at the pipe's interior surface, causing breaks, gaps, and holes.

Do All Pipes Corrode?

The answer to this question depends on the type and cause of the corrosion. Corrosion often affects metal pipes. Plastic-based pipes, such as PVC (or polyvinyl chloride), aren't likely to have this type of problem. But this doesn't mean that PVC or other non-metal pipes can't carry water that corrodes metal fittings or fixtures. According to research from the American Chemical Society, PVC pipes are susceptible to lead and copper leaching. This can create corrosive conditions within the pipes.

What Are the Symptoms of Corrosion?

How do you know if your home has corroded pipes? Pipes that are hidden behind walls, under floors, or in ceiling spaces aren't easy for a homeowner to assess. You can't see the pipes and won't know what state or condition they are in. Likewise, corrosion that happens on the insides of pipes isn't easily visible. This can make it difficult to spot corrosion as soon as it starts.

Homeowners often don't realize that there is a corrosion problem until they see noticeable symptoms. These include discolored water or stains the water leaves behind in tubs, sinks, or other plumbing fixtures, a strange or metallic taste to the tap water, leaks and water damage, low water pressure, or clogs.

Do You Need To Repair Corroded Pipes?

You shouldn't ignore the symptoms of corroded pipes. Left untreated, corrosion can eat away through a pipe and cause serious home damage. As corrosion progresses, the holes and cracks in the pipes allow water to leak into walls, ceilings, floors, kitchen cabinets, bathroom vanities, or almost any other space inside of or outside of your home.

You may start to see damp spots, drips, or puddles under or near the corroded pipes. Along with visible water or moisture, you may smell a musty scent. This is most likely mold that has started to thrive in the damp environment. Not only does mold have an off odor and an unpleasant appearance, it can trigger allergies or breathing problems in household members who are sensitive to this fungus.

The sooner you find the source of a leak and correct corrosion, the less damage the pipes will cause. This doesn't always mean you need to wait until you see drips and puddles to contact a plumber. If you notice discolored water, strange tastes in the water, or low water pressure, but don't see a leak, call a professional. The plumber can assess the issue and may find the corroded pipes before the water they will eventually leak could flood your home.

How Should You Repair Corroded Pipes?

You should never attempt to repair corroded pipes yourself. This could result in additional damage to your home's plumbing system. A DIY repair may not completely solve the problem. This could leave your home open to future water damage. While placing a piece of duct tape around the offending area may seem like an easy fix, the corrosion will only continue to spread. The best repair for corrosion is a professional pipe replacement service.
