A slab leak is one of the most serious plumbing problems a homeowner in Oceanside or San Diego County can face. Left untreated, a slab leak can cause foundation damage, mold growth, and skyrocketing water bills. In this guide, Drains4Less — Oceanside’s top-rated plumber — walks you through how to identify a slab leak early and what to do next.
What Is a Slab Leak?
A slab leak occurs when one of the water or drain pipes running beneath your home’s concrete foundation develops a crack or hole. Because these pipes are buried under concrete, slab leaks are often invisible until significant damage has already occurred.
5 Warning Signs of a Slab Leak
- Unexplained spike in your water bill: If your water usage hasn’t changed but your bill has jumped, water may be escaping through a slab leak.
- Sound of running water with nothing turned on: Press your ear to the floor or wall. If you hear a constant hissing or trickling sound, it could be a pipe leak beneath the slab.
- Warm or wet spots on the floor: Hot water line leaks often create warm patches on tile or hardwood floors.
- Cracks in walls or flooring: As water saturates the soil beneath your foundation, it can cause shifting that cracks walls and floors.
- Low water pressure throughout the home: A significant underground leak reduces pressure to your fixtures.
What to Do If You Suspect a Slab Leak in Oceanside
Do not ignore the signs. The longer a slab leak goes unrepaired, the more structural damage it causes. Here’s what to do:
- Turn off your water main to stop further flooding.
- Call a licensed plumber immediately for professional leak detection.
- Avoid using water until the leak has been located and repaired.
