Repiping versus pipelining sewer lines isn’t a renovation project people like to discuss, but when your sewer line needs repair, one or both of these methods are the solution. Which one to use, depends on your situation and your budget.
Pipelining is for both water/sewer and gas lines. It’s commonly used when replacing pipes would require a cost-prohibitive excavation or expensive cutting into walls and foundation.
Pipelining involves draining and drying the supply pipes. Then they’re sandblasted clean. After that, an epoxy coating is blown into pipes and allowed to dry. The result is a coating that stops corrosion and extends the life of the pipe. It’s also used in buildings with lead pipes to block water from absorbing the lead.
Pipelining is common in apartment and office buildings where the process of replacing pipes [repiping] would be more expensive and inconvenient. It’s also a more popular alternative to repiping that requires expensive excavation costs or cutting a foundation.
Pipelining resists corrosion better than new pipes. It’s often smart to have your incoming water supply tested before deciding between repiping and pipelining so you can make an informed decision.
If pipelining is more convenient, cost-effective and holds up better, why bother with repiping at all? First, pipelining won’t work if there’s an actual hole or similar damage to a pipe. Second, repiping lasts longer. Pipelining generally has warranties of 10 years or more. New pipes last decades.
