Carbon Steel in Potable Water System Water treatment distribution. Hello,Is it acceptable to use carbon steel pipe in a potable water system I am currently upgrading a fire protection system at a complex with approximately 5 buildings.

This means that all the fire water and potable water for the buildings run through the bypass. This bypass piping along with the rest of the fire system piping is made from carbon steel. The water main from the town is made of ductile iron. I had contractor look at the fire pump regarding some upgrades to the system and he advised me that the carbon steel piping is not allowed by the National Plumbing Code of Canada.
