There are several signs that may indicate your home requires repiping. Persistent leaks often suggest that you're facing larger plumbing problems, while rusty or discolored water can signal corroding pipes, warning you to consider copper pipe plumbing or other durable options. Unusual changes in water pressure, especially if you experience fluctuations, might also indicate the need for repiping. For older homes with outdated materials like galvanized pipes or polybutylene, upgrading to modern, flexible pipes such as PEX can greatly enhance the safety and efficiency of your plumbing system. Additionally, if you hear loud or rattling pipes, this could also be a sign of existing plumbing issues that need immediate attention.
