When should I consider replacing my main water line versus just repairing it?

Deciding between repairing and replacing your main water line depends on the extent of the damage, the age of the pipe, and the frequency of repairs. If your line is old, experiences frequent leaks, or has significant damage like a major break or corrosion, a full replacement is often the more cost-effective and long-term solution. A repair might suffice for a small, isolated leak on a relatively new pipe. Your plumber can assess the situation and recommend the best course of action.
