Why manifold plumbing makes rerouting easier
Many homes built since the 2000s use a PEX manifold: one panel, often near the water heater, with a separate line running to each fixture. When one of those lines leaks under the slab, it can be capped at the manifold and replaced with a new line run through the walls or attic to that one fixture. Nothing else in the house is touched.
Older Center Grove homes with copper branch plumbing can be rerouted too, but the new line usually has to serve several fixtures, so it’s a bigger job.
Choosing between the two
| Situation | Better fit |
|---|---|
| Single leak, accessible spot, pipe in good shape | Spot repair |
| Leak under cabinets, an island or large tile | Reroute |
| PEX manifold home, one fixture line leaking | Reroute that line |
| Copper line with a second pinhole | Reroute or replace that run |
| Polybutylene anywhere in the house | Plan a repipe; see polybutylene pipe replacement |

Flooring and finishes
In many Center Grove homes the real cost of a slab repair is the floor on top: large-format tile, engineered hardwood or LVP running through several rooms. If the leak sits under a continuous floor, matching it after a spot repair can be hard, and a reroute that avoids the floor entirely can cost less overall. Ask for both prices.
Keep a few spare boxes of flooring if you have them; they make patching much easier.
Cost and insurance
National guides put a typical single slab leak repair at about $2,000 to $4,000, spot repairs around $1,500 to $3,500, and reroutes about $600 to $7,500 depending on length and route. A single-fixture PEX reroute is usually at the lower end. See slab leak repair cost.
Many homeowners policies cover access and resulting water damage but not the pipe. See does homeowners insurance cover slab leaks?.
Slab Leak Repair: questions from Center Grove homeowners
Can just one line be rerouted?
In homes with a PEX manifold, yes. The leaking line is capped at the manifold and a new line is run to that fixture through the walls or attic.
Is a reroute better than breaking the slab?
Often, when the leak is under cabinets or continuous flooring, or the pipe is old copper. A spot repair is usually the better value for a first leak in an easy spot.
Do you repair slab leaks in Center Grove?
Yes. We pinpoint the leak and our plumbing partner makes the repair, or we give your own plumber the marked spot and report.
How long does a reroute take?
