Do pipes rust on the inside?

Rust occurs on both the inside and outside of pipes. Internal corrosion forms through high pH levels in the water, dissolving a metal pipe’s inner protective layer. External corrosion usually forms through leakage. When left unchecked, pipes build up with rust or limescale and block water flow.2022-03-07

Can galvanized steel be left outside?

What causes galvanized pipe corrosion?

Galvanized water pipe corrosion is most often caused by years of calcium and magnesium build-up. If caught early enough, corrosion can be cleared away with plumbing-grade hydro-jet or sandblasting equipment. Cleaning the inside of pipes every few years is a good preventive practice.2017-05-25

How long does it take galvanized pipe to corrode?
