A concealed diverter valve is a type of shower valve where the main body is installed within the wall, leaving only the control lever and trim plate visible. It allows for managing water flow to different outlets in a shower system.
This specific model is a single outlet valve. For a multi-function shower panel requiring control of several outlets simultaneously or independently, you would typically need a diverter valve with multiple outlets or a more complex control system.
Use a soft, damp cloth to wipe the surface. Avoid using any abrasive cleaners or chemicals, as these can damage the finish. Mild soap and water can be used if necessary, followed by drying with a clean cloth.
The valve itself comes with a 15-year guarantee against manufacturing defects. However, the guarantee specifically supplied by RAK Ceramics for this variant is 6 months, excluding damage from incorrect fitting, misuse, or normal wear and tear.
Due to its concealed nature and the need for precise connections within the wall, professional installation by a qualified plumber is strongly recommended to ensure proper function and prevent potential water damage.
The valve has a compact footprint with dimensions of 70mm (left to right) and 95mm (front to back/depth).
The valve is constructed from high-quality brass for durability and longevity.
Check that the diverter is fully open to the selected outlet. Ensure there are no blockages in the connected shower head or pipework. Verify that the main water supply pressure meets the valve's requirements.
The lever mechanism may require lubrication or adjustment. If the issue persists, the valve may need servicing or replacement, which requires accessing the concealed unit.
This usually indicates an issue with the seals or connections behind the wall. Turn off the water supply and consult a professional plumber to inspect and repair the concealed valve body.
Ensure the valve is correctly installed and balanced. If the problem persists, an issue with the hot or cold water supply to the valve may be present, requiring professional diagnosis.
Setup: This is a concealed, wall-mounted valve. Installation requires opening the wall cavity to connect the valve body to the main water supply and the outlet pipework. It is crucial to follow the manufacturer's detailed installation guide and ensure all connections are watertight to prevent leaks behind the wall. Professional plumbing expertise is highly recommended for a correct and safe installation.
Compatibility: This valve is designed for single-outlet systems. Ensure it is compatible with your chosen shower head or other single water delivery point. The required water pressure and temperature ranges should be verified against your home's plumbing system to ensure optimal performance.
Care: To maintain the matt black finish, clean the visible trim plate with a soft, damp cloth. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish. For internal components, regular maintenance will depend on water quality; however, typical care involves ensuring the lever operates smoothly. RAK Ceramics advises that the 15-year guarantee on the valve covers manufacturing defects, excluding issues arising from incorrect fitting or general wear and tear.
