Hot-side slab leaks
Why it happens here
1990s copper plus hard water.
What we do
Leak location, then reroute or spot repair.
1990s homes on land that was once one of Southern California's big cattle ranches.
Walter Vail began buying land in the Temecula Valley in 1904, and the Vail Ranch ran cattle here for decades before it was sold to a Kaiser and Aetna partnership in 1964 and became Rancho California. The Vail Ranch neighborhoods south of Temecula Parkway were built largely in the 1990s and early 2000s.
At 25 to 35 years old, these homes sit right in the window where copper under the slab, original pressure regulators and second-generation water heaters all need attention.

Land history
Vail Ranch, 1904

The 1990s were the biggest decade for Temecula home building. Census data shows 30.7% of the city's housing went up between 1990 and 1999. Vail Ranch is a big part of that. Those homes typically have copper supply lines under the slab and ABS drains.
Slab leaks are the call we get most here, usually a hot line under a kitchen or master bath. After a second leak, most owners choose a repipe overhead rather than continuing spot repairs.
Vail Headquarters, the restored ranch headquarters near Temecula Parkway and Redhawk Parkway, is a reminder of how new most of the houses around it really are.
