average cost of re plumbing a mobile home
1 The price of copper has increased dramatically in recent years, and re-plumbing a house with copper can cost $2,500-$15,000 or more. 2  For example, Pete Rodriguez of Atlantic Re-Plumbing says a 2-1/2-bathroom house that costs $3,700 to re-plumb with CPVC would start at $4,500 in copper, and could cost more.
