5.2 Valve Installation
- Montar a válvula: Secure the valve body to a sturdy framing member within the wall opening using the provided mounting bracket and screws. Ensure the valve is level and at the correct depth relative to the finished wall surface.
- Conectar as liñas de auga: Connect the hot and cold water supply lines to the respective 1/2" PEX crimp (1807) inlets on the valve. Use appropriate PEX crimping tools and fittings to ensure secure, leak-free connections.
- Connect Outlet Lines: Connect the showerhead and/or tub spout outlet lines to the valve's PEX outlets.

6. Instrucións de funcionamento
The Grohsafe Universal Pressure Balance Rough-In Valve works in conjunction with a compatible GROHE trim kit (sold separately) to control water flow and temperature. Once the trim kit is installed, the valve's internal components, including the diaphragm cartridge and handle limit stop, ensure a consistent and safe showering experience.
- Control de temperatura: The handle on your trim kit will rotate to adjust the water temperature. The integrated handle limit stop within the rough-in valve can be set during installation to prevent excessively hot water, enhancing safety.
- Equilibrio de presión: The pressure balance feature automatically adjusts the mix of hot and cold water to maintain a constant temperature, even if there are sudden pressure drops in either the hot or cold supply lines (e.g., someone flushes a toilet).
- GROHE SilkMove: The ceramic cartridge technology provides smooth and precise control over water flow and temperature with minimal effort.
7. Mantemento
Regular maintenance helps ensure the longevity and optimal performance of your GROHE valve.
- Limpeza: The rough-in valve itself is concealed and generally does not require cleaning. For the visible trim kit, use a soft cloth and mild soap. Avoid abrasive cleaners or harsh chemicals.
- Substitución do cartucho: Over time, the diaphragm cartridge (part of the Grohe SilkMove technology) may require replacement if you experience issues with temperature control or leaks. Refer to your trim kit's manual or GROHE's official website for specific cartridge replacement instructions and part numbers. This typically involves turning off the water supply at the service stops or main, removing the trim, and replacing the cartridge.
- Válvulas de retención: The integrated check valves prevent cross-flow of hot and cold water. If you suspect issues with water mixing, these may need inspection by a professional.
