Can galvanized steel pipe still be used for new water lines in a house?
Friday, June 15, 2018
Yes, it is still approved by the building codes for both service pipe to a house
and distribution pipes inside it. Galvanized pipe was often installed in new homes until the early-1970s, when copper pipe became more popular, likely due to the corrosion problems galvanized steel suffers as it ages. Copper was then dethroned by plastic pipes like CPVC and PEX at the turn of the century. Today we usually only see galvanized used for repairs of existing pipe, but it is still allowed for new installations.
