UNDERGROUND WATER LEAK DETECTION

Find the leak without digging up the property to look for it.

Underground water leaks can be difficult to locate because the source may be far from where water finally becomes visible. Mainline Leak Detection uses specialized, non-invasive technology to pinpoint leaks in buried water lines—helping eliminate unnecessary excavation and giving your repair professional a targeted location to work from.


Signs of an Underground Water Leak


Because the problem is hidden below ground, an underground leak may go unnoticed until other symptoms begin to appear. Warning signs can include:


  • Unexplained increases in your water bill
  • Water meter activity when no water is being used
  • Persistent wet or unusually soft areas in the yard
  • Pooling water without recent rain
  • Warm or damp areas on floors
  • Moisture, mildew or unexplained water damage
  • A water pump running when no water is being used
  • A sump pump operating frequently without recent rain


Underground leaks can occur in water service lines, supply lines, irrigation systems and other buried piping. Pinpointing the leak before excavation begins allows the repair to be focused where it's actually needed—reducing digging, property damage, time and expense.
