Homes built over a century ago will likely have lead pipes. These pipes aren’t the best material, and if any lead gets into the water supply, it could pose a health risk. Most homes with lead pipes have been updated, but it’s important to check if you have an older home.

Galvanized steel is another material that was common in the mid-century, though less common now. It may also be used in homes built prior to the 1940s. Galvanized steel is durable, but it corrodes over time. This can make it prone to leaks or sediment that can end up in your drinking water.
