✓ The existing shower valve no longer operated properly
✓ The homeowner could not use the tub and shower
Rear-wall access allowed us to replace the valve and affected piping while preserving the finished shower tile.
Existing Valve Connections
✓ Rear-wall access exposed the existing shower valve and piping
✓ Sections of the copper piping showed visible corrosion
✓ The valve and affected connections required replacement
The rear-wall openings provided access to replace the valve and corroded piping without disturbing the finished shower tile.

✓ Hot- and cold-water connections rebuilt
✓ New copper tub-spout connection installed
The rebuilt copper piping connected the new valve to the water supplies, showerhead, and tub spout. After testing the connections, we installed the finished trim.

The remaining water lines and wall cavity were prepared for the new valve and rebuilt copper connections.
