Plumbing 101

I have seen it more often than once! People using the wrong type of pipe for a plumbing project. This metal pipe has no business being connected to a hose riser! Copper, PVC, PEX, and the like are suitable for plumbing applications due to the fact that they cannot rust. Metal pipes not only rust they also can cause electrolysis which can accelerate the break down of metal and copper pipes! Look at the inside of this pipe! It was almost completely closed off!
