Under-Slab Copper Manifold Leak Repair
On February 26, 2026, we completed a professional slab leak repair in Riverview, FL involving a leaking 1-inch copper water line feeding a copper manifold system. Under-slab plumbing leaks require precise access, careful concrete removal, and properly prepared copper connections to ensure a long-term solution.
After confirming the leak location, we opened the slab using controlled demolition techniques to expose the affected piping. Once visible, the damaged copper section was removed and replaced using proper pipe preparation methods to maintain structural integrity and water pressure performance.
The system was pressure tested after repair to confirm a watertight seal. A nearby water heater was temporarily disconnected and moved to allow full access to the work area, then professionally reinstalled once the under-slab copper repair was complete.
Existing Water Heater Before Access Work
This image shows the original water heater installation before beginning the slab leak repair. The unit was located directly adjacent to the affected slab area, requiring temporary disconnection and repositioning to safely access the under-slab copper water line.
Concrete Slab Opened to Expose Copper Line
After using a jack hammer for controlled concrete removal, the slab was opened to reveal the vertical copper supply piping. The exposed area shows the manifold feed line and surrounding plumbing that required repair.
Active Repair Area and Equipment Setup
This photo captures the active repair area with plumbing tools and equipment staged nearby. Proper setup is essential for efficient under-slab plumbing repair, allowing safe cutting, pipe removal, and copper fitting installation.
Exposed Copper Manifold Feed Line
With the slab open, we exposed the copper piping within the wall framing and near the slab penetration. The damaged section of the 1-inch copper line feeding the manifold was identified and prepared for replacement.
New Copper Section Installed
A new section of copper piping was installed to replace the compromised portion beneath the slab. The connections were aligned carefully to maintain proper water flow and system stability before pressure testing.
Water Heater Reinstalled After Repair
After completing the copper manifold feed repair and verifying system pressure, the water heater was reinstalled. Final reconnection ensured secure supply lines and restored full hot water service following the slab leak repair.
