Can you use black pipe for water?

Black pipe, typically used for gas lines, is not recommended for water supply because it can corrode and lead to rust and sediment in the water. Instead, it's better to use pipes specifically designed for water, such as copper, PVC, or PEX. These materials are more suitable for Plumbing applications and ensure safe and clean water delivery. Always check local plumbing codes for the best practices in your area.
