Under-Slab Drain Leak Repair in Chino Hills, CA

Why do drains under the slab fail in Chino Hills?

An under-slab drain leak is a crack, break or separation in the drain and sewer piping beneath your concrete floor, the pipes that carry wastewater from sinks, showers and toilets. Chino Hills, southeast of Diamond Bar across the San Bernardino County line, was largely built more recently than its neighbors, so pipe materials and slab construction vary more from house to house.

For newer two-story tract homes on rolling hills, often with post-tension slabs and plastic or mixed supply lines, drain leaks behave differently from supply leaks. They only leak while water is draining, so the meter will not show them, and over time they can soften the soil under the slab and attract roots.

In Chino Hills, newer tract homes with post-tension slabs and a mix of copper, PEX and CPVC usually have ABS or PVC drains, which do not corrode but can crack or separate if the slab moves.
