Between the municipal water meter at your front curb and the plumbing entry point on the side of your home lies your primary underground water service lateral. Buried 24 to 36 inches beneath your lawn, driveway, and landscaping pavers, this pipe carries continuous 60 to 80 PSI municipal water pressure. When this line fails, thousands of gallons of water can seep into the soil before surface puddles ever appear.
5 Tell-Tale Warning Signs of an Underground Supply Break
- 1. Unexplained Soggy Spots or "Spongy" Turf: Walking across your front lawn and noticing squishy, waterlogged grass even after days of dry Rialto summer heat. Water under pressure will eventually saturate the subsoil and create a localized mud bog.
- 2. Sudden Patches of Unusually Lush, Dark Green Grass: If a specific strip of your lawn is thriving and growing twice as fast as the surrounding grass, underground irrigation or main water is continuously fertilizing the turf roots.
- 3. Sinking Concrete Pavers or Driveway Asphalt: Continuous pressurized subterranean water washes away the fine sand and aggregate bedding beneath driveways, walkways, and patios. If you notice sinking pavers or settling concrete slabs, a main line leak is likely eroding the base.
- 4. Hissing Sounds Near the Exterior Hose Bib: Standing near your front hose connection or pressure regulator and hearing a constant rushing or hissing sound like a running garden hose when everything is turned off.
- 5. Sudden Loss of Household Water Pressure: If water flow drops significantly when multiple fixtures are used at once, a large subterranean fracture is diverting water volume into the surrounding earth.
Why Digging Up Your Entire Yard is Unnecessary
In the past, plumbers would bring an excavator or backhoe to trench a 50-foot trench from the curb to the house, destroying rose bushes, irrigation lines, and decorative brick driveways. This destructive approach added $4,000 to $8,000 in landscape restoration expenses.
At Rialto Precision, our technicians use non-invasive electronic line locating. We hook an electro-magnetic transmitter to your water meter, trace the exact path and depth of the buried copper or PVC pipe, and utilize acoustic ground microphones to pinpoint the exact underground fracture. We only dig a surgical 18-inch by 18-inch hole directly over the break to perform the repair.
