If your water pipe has cracked and caused a leak in the slab, it will only continue to lose its integrity along the line. Even if the initial crack is repaired and never leaks again in that same spot, the pipe quality is already compromised and will continue to cause damage in the future. Leaky pipes also have the potential to contaminate your drinking water, destroy your flooring and walls, or extensively damage other areas of your home. Pipe replacement is a much more reliable and lasting solution.
