Underground water line leaks can waste thousands of gallons and cause expensive property damage to your Fontana, Upland, or Rancho Cucamonga home. AS Plumbing & Mechanical uses advanced leak detection technology to find these hidden problems before they become disasters.

Our skilled technicians locate leaks in main water lines running from the street to your house, as well as branch lines that supply water throughout your property. We use electronic detection equipment, ground microphones, and pressure testing to pinpoint leaks without digging up your entire yard.

Homeowners throughout Corona, Redlands, Glendora, and nearby areas call us when they notice unexplained wet spots in their yard, unusually high water bills, or low water pressure. These signs often indicate water line leaks that need immediate professional attention.

We understand that water line problems are urgent. Our team responds quickly to assess your situation, locate the leak precisely, and recommend the most cost effective repair option. This targeted approach saves you money on both detection and repairs while protecting your landscape and foundation.
