Product Information
Full details
The GROHE Rapido UMB (38787000) is a concealed installation system designed for urinals, suitable for both manual actuation and Tectron infra-red electronic 6V systems. It offers a robust water group with a stop valve and includes an installation box with gaskets for versatile mounting options in dry cladding and masonry. A key benefit is its shortenable inspection shaft, protecting it during construction. A potential caveat is the need for professional installation due to its concealed nature.

Can this be installed in any wall type?
Yes, the included installation box is designed for both dry cladding (e.g., plasterboard) and masonry-in applications.
How is maintenance performed on this concealed unit?
Maintenance is performed by accessing the unit through the shortenable inspection shaft, which allows for servicing without major wall disruption.
Is professional installation required?
Yes, due to its concealed nature and integration with water supply lines, professional plumbing installation is required.
Troubleshooting
No water flow to urinal.
Check that the integrated stop valve is fully open. Verify main water supply is active and pressure is within the 0.5-10 bar range.
Manual flush button not working.
Ensure the flush actuator is correctly connected to the roughing-in set. Check for any obstructions or damage to the linkage mechanism.
Infra-red sensor not activating flush.
Verify the electronic module is correctly powered (6V). Check sensor alignment and clean the sensor lens. Ensure batteries (if applicable to the final trim set) are replaced.
Leak detected.
Access the unit via the inspection shaft and check all connections. Tighten any loose fittings. If the leak persists from the valve body, professional servicing may be required.

Setup, Compatibility & Care
Setup: The Rapido UMB is a roughing-in set and requires professional plumbing installation. It involves mounting the main body within the wall cavity, connecting it to the water supply, and ensuring the inspection shaft is accessible. The final installation set (which includes the flush actuator or infra-red sensor) is then attached to the wall plate. Ensure the flow pressure is between 0.5 and 10 bar.
Compatibility: This unit is designed for urinal applications and is compatible with GROHE's manual flush actuators and Tectron infra-red electronic 6V systems. Final trim sets for urinal flush valves are sold separately and must be chosen based on the desired actuation method.
Care: As the main components are concealed, routine care involves cleaning the visible flush actuator or sensor plate. The internal components are accessed via the inspection shaft for maintenance. Use a damp cloth to clean external surfaces; avoid abrasive cleaners. Regular professional checks are recommended for optimal long-term performance.
