The answer to 'how long does pipe repair last' is that the lifespan of pipe repairs can vary significantly depending on the type of repair, the materials used, and the overall condition of the plumbing system. In general, a well-executed pipe repair using high-quality materials can last anywhere from 10 to 50 years or more, provided there are no other underlying issues with the plumbing.
For minor repairs, such as fixing a small leak or replacing a section of pipe, the repair can often last 10-20 years before needing further attention. More extensive repairs, like relining or replacing an entire pipe run, can have a lifespan of 20-50 years or longer if the rest of the plumbing is in good condition. It's important to note that the longevity of a pipe repair also depends on factors like water quality, environmental conditions, and proper maintenance.
