Direct Answer: Common signs of a main line leak include an unexplained jump in your water bill, a "spongy" or unusually green patch in your yard, or a drop in water pressure throughout the house.

In areas like Lexington or Chapin, shifting clay soil can put stress on underground pipes. If you suspect a leak, turn off all water inside the house and check your water meter; if the little dial is still spinning, water is escaping somewhere between the street and your front door.
