Slab Leak Detection & Repair FAQs — San Marino, CA

What causes slab leaks in San Marino homes?

Corrosion, abrasion where pipes rub against concrete or gravel, poor original installation and ground movement are common causes.

Is it better to repair or reroute a slab leak?

If the pipes are in good shape, a spot repair can work. If they've leaked before, rerouting is usually the longer-lasting fix.

Will you have to jackhammer my floor?

Not always. Rerouting runs new pipe through walls or the attic and avoids breaking the slab.

Does insurance cover slab leaks?

Many policies cover the access and resulting damage but not the pipe itself. Check with your insurer.

Do you offer slab leak detection near me in San Marino?

Yes. Coco Plumbing Systems provides slab leak detection throughout San Marino and nearby San Gabriel, Alhambra and Pasadena communities. Call (888) 480-9811 to schedule or for 24/7 emergency help.
