Laufen 1/2" Bottom Entry Cistern Inlet Float Valve
The Laufen 2.9247.1.000.000.1 (often referenced in trade catalogues as H8924710000001) is the authentic OEM bottom-entry cistern inlet fill valve manufactured specifically for Laufen ceramic WC suites. Built with a standard UK 1/2" BSP threaded connection shank, this float-operated valve provides precise water level management, rapid refill times, and acoustic dampening to minimise filling noise. Ideal for replacing dripping, slow-filling, or calcified valves, it restores original factory performance and prevents water running continuously into the toilet bowl.

Key Features
- Original Laufen Specification: Engineered to original tolerances to fit inside Laufen ceramic cistern tanks without catching on flush valves.
- 1/2" BSP Connection: Fits standard UK domestic water supply tailpipes and flexible tap/cistern connectors.
- Precise Float Level Adjustment: Threaded adjustment rod allows accurate setting of internal water lines for full and partial flushes.
- Quiet Hydraulic Shut-Off: Smooth closing diaphragm mechanism reduces water hammer and hydraulic shock across high and low pressures.
- Limescale-Resistant Internal Components: Precision-moulded technical polymers resist mineral fouling and hard-water buildup.
Installation & Compatibility Guidance
Designed strictly for bottom-entry Laufen ceramic cisterns where the cold water supply connects through the hole in the base of the tank (compatible with ranges including Laufen Pro, Palace, Living, and Alessi suites using bottom water feeds). Note: This valve is not suitable for side-entry cisterns (which require Laufen MPN 2.9147.0 / 3/8" side valves). Always isolate the supply and flush line debris before attaching the connector nut.
