Siamp BCM 800 Dual Flush Plate Chrome — 31185410
The Siamp 31185410 BCM 800 is an authentic OEM dual-flush actuator control plate engineered specifically for the Siamp Verso 800 concealed cistern family. Finished in a mirror polished chrome, this durable surface plate provides responsive mechanical dual-flush control (full flush and water-saving eco flush) while serving as the removable maintenance hatch to access internal cistern valves without disturbing wall finishes.

Key Features
- Dedicated Verso 800 Geometry: Designed specifically for the mechanical linkage layout and bracket dimensions of the Siamp Verso 800 (BCM 800) concealed cistern.
- Mechanical Dual Flush Control: Independent full-flush and reduced eco-flush push buttons deliver smooth, tactile feedback to minimise water usage.
- High-Gloss Polished Chrome: Multi-layer chrome plating over tough ABS thermoplastic resists everyday wear, scratching, and household bathroom cleaners.
- Tool-Free Service Hatch: Unclips directly from its mounting plate to provide clear access to internal fill and flush valves without cutting or removing wall tiles.
Installation & Compatibility Notes
Cistern Model Verification: This actuator plate is exclusively engineered for the Siamp Verso 800 / BCM 800 series. It is NOT compatible with Siamp Intra, Siamp BCM 350/500, or concealed cisterns from Geberit, Grohe, or Schwab.
Fitting Advice: Secure the counter-frame squarely onto the cistern inspection tunnel. Adjust the mechanical actuating push rods so that they sit approximately 1mm off the valve lever balance arms; setting rods under active tension will prevent the internal flush valve silicone seal from seating, resulting in a constant trickle into the toilet bowl.
Compatible Replacement Spares & Systems

- Associated Discharge Valve: Siamp mechanical dual-flush valve assembly for Verso 800
