Step-by-Step Installation Guide

1. Turn Off Water Supply

• Shut off main water supply or the individual supply lines to that bathroom.

• Open existing fixtures to relieve pressure.

2. Remove Old Fixtures (If Replacing)

• Disconnect the old shower head, arm, valve trim, handles, etc.

• Remove any trim plates, old caulk, and clean the wall area.

3. Rough-In Plumbing & Valve Installation

• In the wall cavity, ensure the hot and cold supply pipes reach the correct centers for the new valve.

• Mount the valve body firmly to studs, ensuring it’s level and positioned at the proper depth so that the finished trim will sit flush with the finished wall surface.

• Connect the hot and cold water supply lines to the valve inlets using appropriate fittings and apply Teflon tape on threaded joints.

• Install the diverter, cartridge, or internal parts according to the manufacturer’s instructions.

4. Install Drain & Waste (If included)

• If your shower set includes a tub spout or diverter to the drain, connect the outlet to the shower drain line securely and ensure a watertight seal.

5. Mount Shower Arm & Head

• Wrap Teflon tape around the threads of the shower arm.

• Screw the arm into the outlet on the valve or into wall plumbing.

• Attach the shower head to the arm (again using Teflon tape for seals).

• If there is a handheld unit, mount the bracket on the wall, connect the hose, and attach to the handheld.

6. Trim & Handle Installation

• Install the escutcheon or trim plate over the valve opening.

• Insert the handle(s) onto the valve stem(s) and secure them (screws, set screws).

• Ensure the handles move smoothly and align properly.

7. Secure and Seal Fixtures

• Use silicone sealant around the edges of trim plate or wall joints to prevent water infiltration.

• Tighten all fasteners and ensure everything is straight and stable.

8. Turn On Water & Test

• Turn the water supply back on slowly.

• Check for leaks at all connections (valve, hose, joints).

• Operate the shower, test hot and cold, diverter functions, pressure.

• Make any adjustments or tighten leaks.

9. Final Checks & Finishing

• Ensure water flows properly with no drips or leaks.

• Wipe excess sealant.

• Install any decorative caps or covers.
