Metal plumbing pipes in homes built pre 2000 are run underneath the concrete slab. Unfortunately, over time these pipes become weak and brittle causing the pipes to fail, resulting in a leak. So, how can this leak be found/fixed?
Q: What causes pipes underneath the slab to leak?
A: Ground movement/earthquakes, rebar pressing on pipes, overlapping pipes, hot soils, chloramines, electrolysis, debris/rock from concrete.
For the experts, determining the location of the leak is simple.
