Damp or Soggy Areas in Your Yard:

  • Keep an eye out for wet or soggy ground patches especially in areas where the soil is typically dry.
  • Even during dry weather, persistent moisture in specific spots suggests a potential underground leak.

Unusual Vegetation Growth:

  • Lush or unusually green grass or vegetation patches in your yard’s isolated areas may indicate a water leak below the surface.
  • The presence of thriving vegetation in otherwise arid or sparse regions can be a telltale sign of underground moisture.

Low Water Pressure:

  • Decreased water pressure throughout your home particularly in specific areas can be a symptom of an underground leak.
  • If you notice a significant drop in water pressure without any apparent cause such as a closed valve or faucet it warrants further investigation.

Sounds of Running Water:

  • Audible hissing, gurgling or running water noises, especially when no faucets or appliances are used may suggest a hidden leak.
  • Pay attention to any unusual sounds emanating from walls floors or underground pipes as they could indicate the presence of a leak.

Cracks or Bulges:

  • Structural damage such as cracks or bulges in your home’s foundation or walls can indicate underlying water leaks.
  • Excess moisture from underground leaks can weaken your property’s structural integrity leading to visible damage over time.

Mold or Mildew Growth:
