> new installations of those lines has been illegal since 1986 in the US
News to me. Do you have a citation for that?
In the San Jose area we get junk mail almost monthly imploring us to buy insurance against the cost of replacing our water lines, because of their age. So I would have assumed that they all get replaced every 50 years or so.
Copper is usually fine up to 75-100 years old, but a lot of houses have galvanized pipe, which rusts pretty severely over time. Itβs not uncommon for them to rust almost closed within 25 years.
PVC can get brittle, and PE pipe has notorious problems with connectors corroding/failing.
A lot of older sewer lines are clay or cast iron, and they also crack or rust through.
Like wiring, eventually it makes sense to replace them.
