Well owners should be aware that galvanized pipes can be a common component in older well systems. Galvanized pipes are made of steel coated with a layer of zinc to prevent corrosion. Over time, the zinc coating on galvanized pipes can deteriorate, leading to rust and corrosion. Corrosion in galvanized pipes can affect the quality of your well water, causing discoloration, a metallic taste, and even health concerns.
If your well has galvanized pipes, it is recommended to monitor the condition of the pipes regularly and consider replacing them if signs of corrosion are present. Corrosion in galvanized pipes can also lead to leaks and reduced water flow, which can impact the overall performance of your well system.
If you have galvanized pipes in your well system, it is advisable to install a sediment filter to protect your other equipment and ensure the quality of your well water. Consult with a professional well contractor or plumber for specific guidance and recommendations regarding galvanized pipes in your well system.
To ensure you are protecting your family’s health, we have developed a set of recommendations for testing that are provided in our article, "What do I need to know about sampling my well water?", including if you have galvanized piping.
How can I tell if I have galvanized piping?
Here's how you can determine if your well has galvanized piping:
Visual Inspection: Galvanized pipes are typically made of steel with a zinc coating, which gives them a grayish-silver color. Look for signs of dullness or rust on the pipes. If the pipes are painted, lightly scratch them to see the true color.
Magnet Test: You can perform a magnet test by placing a magnet against the pipe. If the magnet sticks, the pipe is likely made of steel, indicating it may be galvanized. If the magnet does not stick, the pipe may be made of a different material, such as copper or PVC.
Professional Inspection: If you're unsure about the material of your pipes, consider hiring a professional plumber or well service provider to inspect your system and provide guidance on maintenance or replacement.
Newer systems or those that have been updated typically do not have galvanized pipes.
