Hey everyone. What in the world causes this much corrosion (copper turning green on its entire surface)? The space is an outdoor-access utility room. The well pressure tank’s galvanized pipe is green like this as well. Anyone have an idea why this happens?
Exposure to chlorine will do it.
It’s the well water. Have it tested.
Condensation from the cold well water and of course the water itself.
Copper pipe electrolysis is a copper water main killer.
The steel tank is oxidized. Almost pitted through I suspect.
There are copper pipes, unions, steel tank, as well, electricity for the pump.
Pick you choice.
Perhaps an intense amount of condensation during extreme conditions, cold and/or hot.
Welcome to the forum Andy

Good luck in your inspector endeavor.
You have a good day sir
