REpair leak or Repipe?
That is the question we deal with on a regular basis, depending on the water line's location weather it is under a concrete slab or in a grass area, if the pipe's are old, or about a few years old.
What is the best route, that will have to be discussed, sometimes the leak is a new construction mistake, or if the pipe was repaired, it can be a sign of the material reaching it's life expectancy and needs to be completely replaced.
Most of the water pipe's that are underground, should be rerouted to the attic or in a dropped ceiling for maintenance, inspection, and easy access for modifications or replacement.
