Slab Leak

Signs that you’re dealing with a slab leak

  • Hearing the sound of running water when water isn’t being used in any room in the house.
  • A hot spot on the floor could indicate a hot water line leak.
  • Mysterious cracks in walls or flooring.
  • Mildew or excessive moisture under carpets could indicate the slab is cracked.
  • Excessively high water bills, even though your usage hasn’t changed

What causes slab leaks?

  • Soil corrosion- Your underground water pipes come in direct contact with the soil, surrounding your home. The chemicals in the soil interact with the metal pipes, which leads to corrosion of the water lines, meaning their internal and external walls start to break down over time. Hot water lines are more likely to corrode from the outside due to heat and chemical contained in the soil. Cold water lines tend to deteriorate from the inside out, the cause of which is electrolysis happening inside the pipe.
  • Abrasion- As water runs through the plumbing system vibrations as well as contraction and expansion of the pipes may occur. This process may lead to the pipes rubbing against abrasive metals such as gravel, concrete or rebar, which can cause gradual abrasion. This constant process will eventually grate the pipe until it creates a leak.
  • Pressure- Water pipes may experience a lot of pressure from poor constriction and shifting of the foundation over the years. Under all these conditions, pipes can be creased or crushed causing them to spring a major leak.

Options when deciding how to take care of slab leaks

  • Spot repair: opening up the slab at the exact spot where the leak is to repair the leaking pipe. This option is cost the most effective for newer construction.
  • Repipe or Reroute: replace the entire line that is causing the leak. This method is most effective when dealing with older plumbing systems that have a history of leaking.
