I just had a new house built, and I discovered they used galvanized steel pipes for the water supply from our well to the pressure tank and water heater (about 100-150 feet away). Also the well casing and pipes inside the well are also galvanized.
I was having some more pipe installed for a gravity tank, and they said galvanized was the best for this, so they began installing more galvanized pipe again. When I began to research it, I discovered many reports of problems with galvanized pipes rusting.
For the new piping, I had them remove what they'd done and they'll replace it with pvc. But the existing supply line will be difficult to replace without digging up portions of 2 retaining walls and a driveway, and the front yard.
Were the builders complete idiots? Or is it really ok to still use galvanized pipes for this sort of work? If it's not, why are galvanized pipes still manufactured?
