Analyzing Copper Plumbing Pipe Failures

Pinhole leak in home copper plumbing has emerged as a significant issue. In the major water distribution system managed by municipalities and water utilities the costs are distributed among all subscribers.

There are also issues of the value of home, insurance rates, health consequences, and taste and odor problems. These issues have become a major concern to home owners. We present a methodology that accounts for random arrivals of leak events in determining the optimal replacement time.
