My house is about 18 yrs old and I'm starting to have pin hole leakes in my copper piping. Plumber says I need to replace all my pipes due to corrossion but the only corrossion I see is where work has been done such as adding a split of value. Any way to fix pin holes without replacing the piping? I read somewhere where a piece of rubber like a tire patch and a ring clamp will work for a LONG time. Any such luck?
