What Causes Cast Iron Pipe to Corrode?
Cast iron pipes are a common form of plumbing used in homes built before 1970. While these pipes were once considered the gold standard of home plumbing, they have several significant drawbacks. Chief among them is that cast iron does not react well to moisture and may corrode over time.
There are several factors that can contribute to the corrosion of cast iron pipes, including the pH level of your water, high levels of chlorine or other chemicals, and even the presence of certain types of soil. Over time, these factors can cause rust to form on the inside of your pipes. As this rust accumulates, it may start to flake off into your water supply — potentially causing a range of health issues if left unchecked.

10 Simple Step-by-step Guidelines on How to Tell if Cast Iron Pipe is Bad
Step 1: Locate Your Cast Iron Pipes
They are typically found in basements, crawl spaces, or under sinks. It is best to start by inspecting the visible pipes first before moving on to harder-to-reach areas. You may also want to check for any signs of leaks or water damage around the pipes. But be cautious and wear safety goggles to avoid any potential hazards. You can also use a flashlight to get a better look at the pipes.
Step 2: Look for Signs of Rust
If you notice any signs of rust on the outside of your pipes, it’s likely that there is corrosion happening on the inside as well. While some minor surface rust may not be cause for concern, widespread or deep rust can indicate that your cast iron pipes are deteriorating and in need of repair or replacement.
But keep in mind that not all rust spots are easily visible, so make sure to inspect the entire length of your pipes. You can use a white cloth or paper towel to wipe down the pipes and check for any signs of rust.
Step 3: Check for Discoloration
Discolored areas on your cast iron pipes may also be an indication of corrosion. If you notice any dark spots or stains on the exterior of your pipes, it’s worth taking a closer look.
These discolorations can also be caused by water leaks, so it’s important to rule out any other potential causes before assuming it’s due to corrosion. But if the discoloration is widespread or appears to be eating away at the pipe, it’s likely a sign of corrosion.
Step 4: Listen for Strange Noises
Gurgling noises coming from your pipes can also indicate that there is corrosion present. As rust builds up inside your pipes, it can create blockages and reduce water flow, leading to these strange noises. If you notice any unusual sounds when using your water, it’s worth investigating further. It could be a sign that your cast iron pipes are in need of attention.
Step 5: Pay Attention to Water Pressure
Corrosion can also affect the water pressure in your home. If you notice a significant reduction in water pressure, it could be due to rust buildup inside your pipes. This is especially true if multiple faucets or fixtures are experiencing low water pressure.
While there are other potential causes for low water pressure, it’s worth considering the possibility of corroded cast iron pipes. But keep in mind that rusty water can also cause low pressure, so make sure to check for both.
Step 6: Look for Leaks
Leaks are another common sign of failing cast iron pipes. If you notice any puddles or damp spots near your pipes, it’s a clear indication that there is a leak present. But keep in mind that not all leaks are visible, so also be on the lookout for any unexplained increases in your water bill. If you suspect a leak but can’t see it, consider calling a professional to come take a closer look.
Step 7: Test Your Water’s pH Level
As mentioned earlier, the pH level of your water can play a significant role in the corrosion of cast iron pipes. If you have concerns about the quality of your water, you can purchase a pH testing kit to determine the acidity levels. If your water is highly acidic, it can speed up the corrosion process and cause further damage to your pipes.
Step 8: Pay Attention to Odors
If your water has an unpleasant odor, it could be a sign that your cast iron pipes are starting to fail. Rust buildup can cause an earthy or metallic smell in your water, which is not only unpleasant but can also indicate the presence of harmful bacteria. If you notice any unusual odors coming from your water supply, it’s worth taking a closer look at your pipes.
Step 9: Consider the Age of Your Home
As mentioned earlier, cast iron pipes were commonly used in homes built before 1970. If your home falls into this category, it’s worth keeping a closer eye on your pipes and scheduling regular inspections to catch any potential issues early on.
You may also want to consider replacing your cast iron pipes with newer, more durable materials. It may be a costly upfront investment, but it can save you from more significant expenses in the long run.
Step 10: Consult a Professional
If you have any concerns about the state of your cast iron pipes, it’s always best to consult with a professional plumber. They can provide expert advice and determine if repairs or replacements are necessary. It’s important not to ignore any warning signs of corroded cast iron pipes, as they can have serious consequences for your health and home.
By following these simple guidelines on how to tell if cast iron pipe is bad and staying proactive, you can ensure the longevity and safety of your plumbing system. So be vigilant and don’t hesitate to seek professional help when needed.
