Pipe corrosion is a common cause of plumbing leaks. Decades of water flow inside metal pipes eventually causes them to break down. In the worst-case scenario, the pipe can burst, causing extensive water damage to your home. Fortunately, there are telltale signs of corroded water pipes. If you notice the following signs, call a local plumbing services contractor in Troy, MI, to correct the problem and avoid further damage:
1. Discolored Water
Water flowing from corroded pipes may appear rusty itself. It may be brown, blue, or green. The water will take on the color of the corrosion in the pipes. Brown water comes from deteriorated steel or iron pipes, while blue-green water can come from old copper pipes.
2. Changes in Water Quality
Aside from how water from corroded pipes looks, it may also have a distinct taste. If it comes from corroded copper lines, it will have a metallic taste. Water from old lead pipes may have a sweet taste. If your water smells metallic, bits of old metal are likely being carried with it due to pipe corrosion.
3. Fluctuations in Water Temperature
If you have a corroded pipe, water can go from warm to cold to warm again, and then back to cold, several times when taking a shower or doing the dishes. Hot water tends to corrode steel pipes more quickly than cold water does. Corrosion also not only affects pipes. It can damage valves, water fixtures, and anti-scald mechanisms, which causes the water temperature to fluctuate.
4. Reduced Water Pressure
Weak water pressure from faucets and showerheads can mean oxidized debris is narrowing your water pipes. Over time, the buildup will get worse and water pressure will continue to decline until there’s barely a trickle. It can get to the point there won’t be enough water to do basic tasks like washing your hands or brushing your teeth.
5. Frequent Pipe Clogs
Pipe corrosion and mineral buildup can cause water lines to clog up. A clog can lead to persistent blockages as the inside of a pipe becomes narrower. It can also cause other debris to get stuck. Since corrosion can lead to holes and cracks in the pipe, have a professional inspect your plumbing system to find signs of corrosion or other damage that needs repair.
6. Water Leaks
If water is leaking from an exposed pipe or water stains are concentrated in one area, you probably have a corroded pipe. Other plumbing issues may be present if the leaks are spread throughout your home. A small leak you can’t seal may be caused by corrosion that’s formed small holes in the pipe. Call for help if a pipe won’t stop dripping or you find puddles of water.
7. Visible Corrosion
Many pipes are hidden behind walls and above ceilings. But you can check exposed pipes for signs of corrosion. Oxidation on the exterior of pipes may look reddish-brown or bluish-green. The substance tends to form a powdery coating. If pipes are corroding on the outside, assume they’re doing the same on the inside and call a plumber for help.
What Causes Pipe Corrosion?
Metal pipes corrode when they interact with oxygen, water, and other elements. Acidic water, hard water minerals, high levels of oxygen, drain cleaning chemicals, high water temperatures, bacteria, sediment, and high-velocity water can accelerate corrosion.
Can I Prevent Pipe Corrosion?
To prevent corrosion or stop it from getting worse, you can:
- Remove any buildup using a pipe cleaner
- Apply an anti-rust paint or coating
- Install vapor barriers to reduce exposure of pipes to moisture
- Install a water filter that reduces acidity
- Use a corrosion inhibitor such as phosphates
- Separate or insulate steel pipes from other metals
- Secure water pipes to avoid corrosion-inducing wear
Can a Corroded Pipe Be Repaired?
It’s possible to fix a small patch of rust. If it can’t be brushed away or dissolved with an acidic solution, an epoxy or a clamp fitting may resolve the problem. Older pipes that are severely corroded should be replaced.
