Change galvanized pipe to copper.

Copper pipe is available in small diameters for installation in tight spaces.
Polyvinyl chloride known as pvc 80 100 yrs.
Supply pipes under constant pressure and therefore most likely to cause water damage when they leak brass.
Copper plumbing is lead free making it safer than galvanized pipe.
Copper is the material most often used by today s home builders and homeowners when installing plumbing.
Steel tube dimensions stainless steel tubing dimension dimensions of steel tube fifty years ago the industry thinking was that because of the inside of copper piping being much smoother than that of galvanized steel it was allowable to reduce the nominal size by one size when going from galvanized steel to copper.
