Completed: Late August 2025 • Access through wall & floor • PEX ↔ PVC transition under slab
For this Brooksville, FL project, we traced an underground water service leak running beneath the slab. To reach the break safely and accurately, we opened the wall and floor to create a clean access point for diagnostics and repair.
Once exposed, we found the failure centered on a PEX to PVC transition. Using rated transition couplings, PEX expansion/crimp tools, and PVC primer & solvent cement, we rebuilt the connection to withstand soil movement and daily water pressure.
We performed a thorough pressure test to confirm a watertight seal before close-up. The final steps included removal of the damaged pipe section, cleanup, and preparing the area for finish restoration.
If you notice pooling water, hissing in walls, or unusual usage, it may indicate a service line leak. We specialize in under-slab plumbing repair, PEX ↔ PVC transitions, and code-compliant underground water line repairs.
We carefully cut and removed a section of wall and floor to reach the leaking service line. Controlled demolition protects finishes and provides a direct path for leak detection, isolation, and under-slab repair.
After exposing sound pipe, we prepped the PEX ↔ PVC transition with clean, square cuts and proper dry-fit. Tools on this step include PEX cutters, expansion/crimp tools, and gauges for correct insertion depth.
We installed a rated PEX-to-PVC coupling per manufacturer specs, using PVC primer & solvent cement on the PVC side and the correct expansion/crimp system on PEX. Proper alignment minimizes joint stress.
With fittings secured, we performed a pressure test to verify a leak-free seal. This step validates the integrity of the underground water line repair before close-up and restoration.
Here is the failed section we cut out. Wear at the transition indicates why the connection began leaking. Removing compromised material is crucial for a durable, code-compliant repair.
This alternate angle shows the condition of the damaged service line. By replacing it with a rated PEX ↔ PVC transition, we restored reliability and water pressure under the slab.
