The Problem: A Hidden Leak Damaging the Subfloor

Leaks in a crawlspace or subfloor are among the most damaging plumbing failures a homeowner can face, because by the time you notice them, the damage is already done.

• Hidden Subfloor Leak: The original 3/4″ copper lines had developed a failure point causing moisture buildup beneath the structure, leading to potential mold and foundation damage.
• Unregulated Water Pressure: The home had no effective pressure control, placing constant stress on every valve, appliance, and fixture in the house.

Our Solution: Copper Repair + Pressure Reducing Valve

• Copper Pipe Leak Repair: We located the exact failure point beneath the subfloor, removed the damaged section, and performed a permanent repair using 3/4″ copper pipe and high-quality fittings.
• Pressure Reducing Valve Installation: We installed a new PRV directly on the main water line immediately after the shutoff valve, the correct position for whole-home pressure protection.
• Service Upgrade + Weatherproofing: We added a new 1/4-turn hose bib using 3/4″ copper for reliable exterior water access, then insulated exposed piping against the coastal elements.

The Result: A Dry Subfloor and Protected Fixtures

The subfloor leak was completely eliminated, protecting the home’s foundation from further damage. With the new PRV in place, water pressure is now regulated consistently across all fixtures, extending the life of the entire plumbing system.
