Monta Vista
Smart Shutoff Install
Installed a Moen Flo automatic shutoff after a repeat pinhole leak in original copper.
Hidden leak in a Cupertino home? We find it without demolition — pinhole leaks in older copper pipe are the most common cause in this city's hard water.
Cupertino’s hard water is good at one destructive thing: pitting the inside of copper pipe over decades until it perforates from the inside out. That failure shows up as a pinhole leak — a small, often slow drip inside a wall or under a slab that can run for weeks before anyone notices, usually first on the water bill rather than on the floor.
Monta Vista and Garden Gate have the oldest copper runs in the city and see the most of these calls; Rancho Rinconada’s mixed-era plumbing follows close behind. We isolate the affected line, then use acoustic listening equipment to pinpoint the exact failure point before recommending anything, so a repair opens one specific spot instead of an exploratory hole.
A smart shutoff valve (we install and set up Moen Flo units) is worth mentioning here specifically because hard-water pinhole failures tend to repeat elsewhere in the same run — a shutoff that catches the next one before it floods a room pays for itself the first time it works.

Decades of mineral-heavy water pit copper pipe from the inside until it perforates — usually noticed on the bill, not the floor.
The city’s original copper runs see the most pinhole failures. Acoustic detection pinpoints the spot before we open anything.
A run that’s failed once often fails again elsewhere. We talk through smart shutoff protection, not just the one repair.

“Water bill jumped for two months before we found out why. They found the pinhole under the hallway in about 40 minutes.”
“Recommended a Flo shutoff after the repair since our pipes are original from the 60s. Good call.”
“Fast, accurate, and didn’t open a single wall we didn’t need opened.”
