Zeus Plumbing provides sewer line repair in San Antonio for homes with failing drain lines — including the cast-iron lines common in older San Antonio homes, which corrode from the inside out until clogs keep coming back. Our slab leak repair in San Antonio covers drain and water lines under your foundation: electronic and acoustic detection pinpoints the leak, then a sewer camera inspection shows exactly what is happening underground before anyone digs.
Wherever the layout allows it, trenchless repair options replace or reline a damaged line without tearing up your yard, driveway or landscaping. When a leak sits directly under the slab, we tunnel beneath it — hand-digging under the foundation to reach the broken pipe.

Warning signs your sewer line is failing
Recurring clogs are the classic sign a San Antonio sewer line is failing — when a drain clears and backs up again within weeks, the problem is usually in the underground line, not the fixture. Watch for a soggy or sunken patch in the yard, sewage odors near drains, gurgling sounds, or multiple drains backing up at once.
Under a slab, the warning signs change: warm spots on the floor, the sound of running water when everything is off, or a water bill that jumps for no reason. Tunneling keeps the repair under the slab instead of through it — we hand-dig beneath the foundation, replace the failed pipe from below and restore the area.
