5. Installation Instructions (Setup)
Before starting, ensure the main water supply is turned off. This shower system is designed for standard U.S. plumbing connections (NPT 1/2").
5.1 Rough-in Valve Installation
- Prepare Wall Opening: Create an opening in the wall suitable for the rough-in valve body. Refer to the dimensions diagram for precise measurements.
- Connect Water Lines: Connect the hot water supply line to the 'H' (Hot) inlet and the cold water supply line to the 'C' (Cold) inlet on the rough-in valve. Use NPT 1/2" connections and apply pipe thread sealant tape to ensure watertight seals.
- Connect Shower Outlets: Connect the fixed shower head outlet to the top NPT 1/2" connector and the handheld shower outlet to the bottom NPT 1/2" connector on the valve body.
- Secure Valve: Mount the rough-in valve securely to the wall studs using appropriate fasteners. Ensure the valve body is level and at the correct depth relative to the finished wall surface (typically 60-80mm from the finished wall).
- Test Connections: Temporarily turn on the water supply to check for leaks. Turn off the water supply once testing is complete.

5.2 Trim Kit Installation
- Install Faceplate: Once the wall is finished, install the decorative faceplate over the rough-in valve, ensuring it is flush with the wall.
- Install Handle: Attach the control handle to the valve stem according to the manufacturer's instructions, securing it with the provided screw.
5.3 Shower Arm and Head Installation
- Install Shower Arm: Apply pipe thread sealant tape to the threaded end of the shower arm and screw it into the fixed shower head outlet in the wall. Tighten securely.
- Attach Shower Head: Screw the 10-inch rainfall shower head onto the threaded end of the shower arm. Hand-tighten, then use a wrench to tighten slightly more, ensuring not to overtighten.
5.4 Handheld Shower Installation
- Install Holder Bracket: Mount the handheld shower holder bracket to the wall at a desired height using the provided hardware.
- Connect Hose: Connect one end of the shower hose to the handheld shower outlet on the valve and the other end to the handheld shower head. Ensure washers are in place and connections are tight.
- Place Handheld Shower: Place the handheld shower into its holder.
6. Operating Instructions
Your Gappo shower system offers two functions: a rainfall shower and a handheld spray. The single handle controls both water temperature and flow.
- Turning On/Off: Rotate the handle to turn the water on or off.
- Temperature Control: Rotate the handle left for hotter water and right for colder water. The pressure balance valve maintains a consistent temperature, preventing sudden changes.
- Function Selection: The system features a diverter to switch between the rainfall shower head and the handheld shower. Operate the diverter knob or lever to select your desired spray function.
- Air Injection Technology: The 10-inch rainfall shower head incorporates air injection technology, mixing water with air to enhance water pressure and simulate a natural rain experience.

7. Maintenance and Care
Regular cleaning and maintenance will help preserve the finish and functionality of your shower system.
- Cleaning the Finish: Clean the matte black finish with a soft, damp cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Cleaning Shower Head Nozzles: The shower head features silicone nozzles that allow for easy removal of mineral deposits. Simply wipe the nozzles with your finger to clear any buildup.
- Material Durability: The faucet features all-metal sturdy construction, made from brass and stainless steel, providing resistance to oxidation and corrosion.

8. Troubleshooting
If you encounter issues with your shower system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Pressure | Clogged shower head nozzles; partially closed shut-off valve; low household water pressure. | Clean shower head nozzles by wiping them; ensure shut-off valves are fully open; consult a plumber if household pressure is consistently low. |
| Water Leaks | Loose connections; damaged O-rings or washers; improper application of thread sealant. | Ensure all connections are tightened properly (do not overtighten); replace damaged O-rings or washers; reapply thread sealant tape if necessary. |
| Inconsistent Water Temperature | Pressure balance valve malfunction; hot/cold water supply issues. | Verify the pressure balance valve is installed correctly; check household hot/cold water supply. If issues persist, contact customer support. |
| Diverter Not Switching Functions | Mineral buildup in diverter; faulty diverter cartridge. | Clean around the diverter mechanism; if problem persists, the diverter cartridge may need replacement. Contact customer support. |
