Introduction
This manual provides instructions for the installation, operation, and maintenance of the GROHE Relexa 5-Port Single-Handle Diverter Valve Trim Kit, model 19905000. This trim kit is designed to be used exclusively with the GROHE diverter rough-in valve 29 714. It features a single round handle for selecting water outlets and is finished with GROHE StarLight chrome for durability and aesthetic appeal.
Setup and Installation
This trim kit is intended for installation onto the pre-installed GROHE diverter rough-in valve 29 714. Ensure the rough-in valve is correctly installed according to its specific instructions before proceeding with the trim kit installation.
Required Tools:
- Adjustable wrench or appropriate hex keys
- Screwdriver (Phillips or flathead, as required)
- Sealant tape (if not already applied to rough-in valve connections)
Installation Steps:
- Prepare the Rough-In Valve: Ensure the rough-in valve 29 714 is securely mounted and all plumbing connections are complete and leak-free.
- Install Escutcheon: Position the escutcheon (cover plate) over the rough-in valve body. Secure it using the provided screws, ensuring it is flush against the wall.
- Attach Diverter Cartridge: If not already part of the rough-in valve, insert the diverter cartridge into the valve body according to the rough-in valve instructions.
- Install Handle Adapter: Secure the handle adapter onto the diverter cartridge stem.
- Mount Handle: Place the round handle onto the handle adapter. Secure the handle with the set screw, typically located on the underside of the handle. Tighten gently to avoid damage.
- Test Operation: Turn on the water supply and test the diverter for proper function and any leaks. Rotate the handle to ensure smooth selection between all 5 ports.

Operating Instructions
The GROHE Relexa 5-Port Diverter Trim Kit allows you to direct water flow to up to five different outlets (e.g., shower head, hand shower, body sprays, tub spout). The single round handle controls the selection of these outlets.
To Operate:
- Ensure the main water supply to your shower/bath is active.
- Rotate the round handle to cycle through the available water outlets. Each distinct position of the handle corresponds to a specific port or combination of ports, depending on the rough-in valve configuration.
- Stop rotating the handle when the desired water outlet is active.
Consult the rough-in valve manual for specific details on which handle positions activate which ports.
Care and Maintenance
To maintain the appearance and functionality of your GROHE Relexa Diverter Trim Kit, follow these guidelines:
- Cleaning the Finish: The GROHE StarLight chrome finish is designed for scratch and tarnish resistance. Clean regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, ammonia-based cleaners, or cleaners containing bleach, acids, or alcohol, as these can damage the finish.
- Drying: After cleaning, rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Internal Components: The internal ceramic components are designed for long-lasting, drip-free performance. If you experience issues with water flow or selection, refer to the troubleshooting section or contact customer support.
Troubleshooting
If you encounter issues with your GROHE Relexa Diverter Trim Kit, consider the following common solutions:
- Difficulty Rotating Handle: Ensure no debris is obstructing the handle's movement. If the handle feels stiff, it may indicate an issue with the diverter cartridge.
- Water Leaks Around Handle/Escutcheon: Check that the escutcheon screws are tightened appropriately and that the trim kit components are properly seated. Leaks from behind the wall may indicate an issue with the rough-in valve installation, requiring professional attention.
- Incorrect Port Selection: If the diverter is not directing water to the correct outlet, verify that the handle was installed correctly onto the cartridge stem. If the issue persists, the diverter cartridge may need inspection or replacement.
- Reduced Water Flow: This is typically related to the main water supply or the rough-in valve itself, not the trim kit. Check water pressure and ensure the rough-in valve is fully open.
For persistent problems, it is recommended to contact a qualified plumber or GROHE customer support.
