Basic Homeowner’s Guide To Slab Leaks

So Why Slab Leaks Happen

A home’s plumbing pipes run both within walls and under the ground. Leaks may occur anywhere in the system, including hard-to-access areas.

Slab leaks can happen for many reasons. Most commonly, copper or galvanized pipes wear out from age and corrosion. Underground pipes face extra stresses (soil expansion/contraction) that can accelerate wear.

Corrosion can be faster if slab pipes carry very alkaline or very acidic water; chemical reactions damage metal pipes. Pipes also degrade from abrasion: thermal expansion causes movement and rubbing against surrounding materials, producing weak spots.

When To Suspect A Slab Leak

Slab leaks are often hard to spot, but close observation reveals clues: wet carpet, damp floorboards, unusual mold growth. You may also hear the faint sound of running water with no apparent source. Other signs include unexplained increases in water bills and low water pressure.

How Slab Leak Repipe Experts in San Diego Fix Slab Leaks

Experienced slab leak repipe experts in San Diego use specialized tools to locate elusive leaks. In simple cases, visible dampness points to the leak. If needed, a San Diego plumber may use sonar, infrared, or helium leak-detection equipment to pinpoint hidden leaks.

Repair methods vary. Sometimes plumbers must dig through concrete (jackhammering) to access the damaged pipe. Another option is to cap the leaking section and reroute with PEX through attic or walls. Often it’s better to replace sections of old, corroded pipe than repeatedly patch them. Replacements provide longer trouble-free service.

If the original slab routing contributed to the problem (pipes run too close to abrasive structures or unpredictable subfloor), a slab leak repair San Diego company can reroute piping to eliminate the risk.

Preventing Future Slab Leaks

You can’t control everything (ground shifting, foundation movement), but you can reduce risk. Test your home water pH periodically with a home kit—readings below 7 or above 8 may warrant a water softener or corrective treatment. Blue or reddish discoloration on fittings also signals pH issues.

Have your water pressure checked. If pressure is high or fluctuating, install a pressure-reducing valve to protect appliances and pipes from pressure spikes.

If you suspect a slab leak, act quickly. Contact a slab leak repair San Diego company for experienced technicians and timely service.

Slab Leak Repair The Correct Way

If you think you have a leak, call a professional for an inspection. Reputable teams will check your water meter and perform a short pressure test. If a leak exists, a slab leak detection team will pinpoint the source so the best repair option can be chosen.

Common repair options:

Direct Access

Direct access (jackhammering to expose the pipe for a spot repair) is sometimes used, but it can be disruptive and temporary. It may require cutting through kitchens, bathrooms, or living areas and is not always recommended.

Pipe Reroute

Pipe rerouting is the industry standard for many slab leaks. It minimizes disruption inside living areas and is often preferred when the leaking section is short or not suitable for epoxy repair. Rerouting may include drywall repair as part of the service.

Epoxy Repair

Epoxy pipe repair can eliminate many slab leaks using only two access points. This option often saves thousands compared to full excavation and frequently comes with long warranties (e.g., 10 years).

Re-Piping

To avoid future slab or pinhole leaks entirely, full re-piping (installing a new water system) may be the best long-term solution. Modern systems and materials can provide years of trouble-free service and manufacturer warranties.
