Slab Leak Pipe Rerouting in Rancho Palos Verdes, CA
The permanent fix for failing under-slab plumbing: abandon the old lines and run new ones where you can see and service them.
Stop Fixing the Pipe. Change Its Path.
Here's the pattern we see constantly in Rancho Palos Verdes: a homeowner gets a pinhole leak repaired under the slab. Eighteen months later, another pinhole — six feet away, same aging copper line, same aggressive soil. Then a third. Each spot repair costs money, each one breaks concrete, and none of them addresses the real problem: the entire under-slab system is at the end of its life.
Rerouting ends the cycle. We disconnect the failing lines beneath your slab and install new ones where they belong — inside walls, through the attic, along routes that can be inspected and serviced. The old pipes stay buried, depressurized and harmless.
When Rerouting Is the Right Call
- Two or more slab leaks within a few years — the system is failing, not the pipe
- Homes with post-tension slabs, where cutting concrete risks severing tension cables
- Expensive flooring (marble, travertine, hardwood) that you'd rather not demolish
- Hillside homes where soil movement will keep stressing any under-slab repair
- Water quality or soil chemistry that's corroding copper from the outside in
What the New Lines Are Made Of
Most reroutes today use PEX tubing — flexible, freeze-resistant, and immune to the corrosion that kills copper. Where code or preference calls for it, we run new copper (type L) with proper sleeving and isolation from concrete and dissimilar metals. Either way, the new system is pressure-tested, permitted, and inspected.
The Process, Day by Day
Day 1: We map the new routes, protect floors and furniture, and begin running lines. The old system stays live as long as possible. Day 2: New lines are connected fixture by fixture, pressure-tested, and the old under-slab lines are capped and abandoned. Day 3 (if needed): Patching, texturing, and paint — we leave walls looking like we were never there.
For Peninsula homes with aging copper, rerouting is very often the most economical long-term answer — one project instead of a decade of emergencies. Call (833) 713-2101 for a free on-site assessment.

Frequently Asked Questions
What exactly is pipe rerouting?
Instead of repairing the leaking pipe under your slab, we abandon it in place and install a brand-new water line routed through walls, ceilings, or the attic. The old line is disconnected and left harmlessly in the ground.
Why is rerouting better than repairing the leak?
A spot repair fixes one failure point in an aging system — but the rest of that 40-year-old line is still under the same soil, under the same stress. Rerouting replaces the entire path, so you're not paying for a second emergency next year.
Will rerouting damage my walls?
We open small, surgical access points to run the new lines, then patch, texture, and paint to match. Most homeowners are surprised how little evidence remains — and there's zero concrete demolition.
How long does a reroute take?
A single line can be done in a day. Whole-home reroutes typically take 1–3 days depending on the home's size and layout. You'll have water every evening — we never leave you dry overnight.
