Reroute or Repair a Slab Leak: What Is the Difference?

How do the options compare?

When does repair make sense?

Repair in place suits a single leak in a pipe that is otherwise in good shape. If the leak is under flooring that is easy to patch, a small opening is the shortest path. If it sits under tile or wood you want to keep, a tunnel from outside can reach it without touching the floor inside.

When does rerouting make sense?

Rerouting suits pipes that have already leaked, show corrosion, or are old enough that more leaks are likely. A new line through the attic or walls replaces the weak section, and the old pipe is capped under the slab. Small wall openings are usually needed and patched afterward.

What questions should you ask the provider?

• Where exactly is the leak, and how deep is it?
• What condition are the rest of the pipes in?
• Which rooms or floors will be affected?
• How long will water be off?
• What happens to the old pipe?

Why does it matter in Pflugerville?

Clay soil in the area moves with wet and dry seasons, which can stress pipes set in a slab. In older neighborhoods with original copper lines, one leak can be a sign of more to come. That is why providers often look at the whole system, not just the leak. Start with slab leak detection in Pflugerville to find the leak first.

What does the choice look like in a Pflugerville home?

Two neighbors on the same street both have a slab leak. In the first home, the leak is under a laundry room with vinyl flooring, the pipes are in good shape, and it is the first leak in twenty years. A small direct access repair makes sense: open a patch of floor, fix the pipe, pour new concrete, and replace a few squares of vinyl.

In the second home, the leak is under new wood floors in the living room, and it is the second leak in three years. Here the provider may suggest rerouting the hot line through the attic. The floor stays untouched, and the weakest stretch of pipe is taken out of service.

What happens on the day of the work?

1. The provider confirms the leak location from detection.
2. Water is shut off to the affected line.
3. For repair, the floor is opened or a tunnel is dug. For a reroute, small openings are made in walls or the attic is accessed.
4. The pipe is repaired or the new line is run and connected.
5. The system is pressure-tested to confirm there are no leaks.
6. Openings are closed and water is turned back on.

How do you decide?

Ask the provider to explain why they recommend one option over another for your home, and what the other options would involve. A good recommendation is based on where the leak is, the age and condition of your pipes, and the flooring above it.

What should you do while you wait for the provider?

Keep the affected line shut off if you can. If the leak is on the hot side, close the cold-water inlet on the water heater so you still have cold water in the rest of the house. Move rugs and furniture away from any damp or warm area, and take photos for your records and your insurer.
