Due to cold, a 3/4 inch flexable copper water pipe used for hot water baseboard heat cracked. The entire length of the remaining pipe cannot be repaired because it expanded and will not accept a 3/4 inch coupler or compression fitting.
Any ideas on how to connect the new piece of pipe to the old without busting open walls to get to the next connector.
use a swaging(i know i’m not spelling that right but it rymes with wedge)to expand the pipe futher to accept the new 3/4″ copper pipe.the pipe becomes it’s own coupling so to speak. you’ll have to heat the pipe to soften it be carefull!
