Installation Instructions
This shower head combo is designed for easy installation without the need for professional tools. It works with all standard 1/2'' pipe threads.
- Prepare the Shower Arm: Ensure your existing shower arm is clean and free of debris. Apply plumber's tape (provided) clockwise around the threads of your existing shower arm.
- Install the 3-Way Water Diverter: Screw the 3-way water diverter onto your existing shower arm. Hand-tighten first, then use a wrench if necessary, but do not overtighten. Ensure a washer is in place for a leak-proof seal.
- Attach the Extension Arm: Screw the 11-inch extension arm onto the top outlet of the 3-way diverter. Ensure a washer is in place and hand-tighten. The extension arm features locking screws for stability; tighten the larger inner hexagon nut during installation.
- Connect the Rainfall Shower Head: Attach the 10-inch rainfall shower head to the end of the extension arm. Ensure a filter and washer are in place for a reliable leak-proof connection. Hand-tighten.
- Connect the Handheld Shower Hose: Attach one end of the 60-inch stainless steel hose to the side outlet of the 3-way diverter. Ensure a washer is in place and hand-tighten.
- Attach the Handheld Shower Head: Connect the handheld shower head to the other end of the 60-inch hose. Ensure a washer is in place and hand-tighten.
- Mount the Handheld Shower Head: Clean the wall surface where you intend to mount the adhesive bracket. Remove the protective film from the adhesive bracket and firmly press it onto the clean, dry wall. Allow it to set for 24 hours before placing the handheld shower head in it.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. If any leaks are detected, tighten the connection slightly until the leak stops.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your shower head combo.
- Cleaning Nozzles: The shower heads feature self-cleaning silicone jets that prevent lime scale build-up. To clean, simply rub your finger across the nozzles to dislodge any mineral deposits.
- General Cleaning: Clean the chrome finish with a soft cloth and mild soap or a non-abrasive bathroom cleaner. Avoid harsh chemicals or abrasive scrubbers, as these can damage the finish.
- Filter Maintenance: Periodically check the filter and washer at the connections for any debris or wear. Clean or replace as needed to maintain water flow and prevent leaks.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks from connections | Loose connections, worn/missing washers, insufficient plumber's tape. | Ensure all connections are hand-tightened. Add more plumber's tape. Check and replace washers if damaged or missing. |
| Low water pressure | Clogged nozzles, debris in filter, water flow restrictor (if installed). | Clean the silicone nozzles. Check and clean the filter. Ensure any water flow restrictors are properly installed or removed according to local regulations. |
| Diverter not switching properly | Internal debris, stiff mechanism. | Flush the system by running water through both heads. If persistent, contact customer support. |
| Handheld shower head falls from bracket | Adhesive not fully cured, surface not clean, bracket damaged. | Ensure surface is clean and dry before applying adhesive bracket. Allow 24 hours for adhesive to cure. Replace bracket if damaged. |
