Overhead PEX Reroute Preserves Custom Hardwood in Seacliff
Real-world diagnostic case study from Seacliff, Huntington Beach, CA
Property & Plumbing Background
A two-story residence in Seacliff experienced a sudden doubling of its monthly water utility bill alongside a localized warm area beneath custom Brazilian walnut hardwood flooring in the main hallway. The homeowner was deeply concerned that repairing the underground leak would necessitate tearing up irreplaceable hardwood boards across the entire first floor.
Diagnostic Protocol & Findings
Our diagnostic technician deployed FLIR thermal imaging and high-gain acoustic ground microphones. We confirmed a pressurized 3/4-inch hot water supply line had ruptured beneath the concrete slab approximately four feet from the downstairs half-bath. The acoustic signature indicated a pinhole spraying at 65 PSI against the sub-slab gravel bed.
The Engineering Solution
Rather than cutting through the custom hardwood and concrete foundation, we recommended an overhead PEX-A reroute. We capped the failed copper line at the water heater manifold and routed commercial-grade 3/4-inch Uponor PEX through attic trusses and vertical interior wall cavities down to the bathroom fixture manifold.
Final Verified Result
The entire reroute was completed in a single day. Water service was fully restored by 4:30 PM with zero cuts made to the customer hardwood floor, preserving thousands of dollars in interior flooring assets.
