Wirquin Flush Mechanism Group

The Wirquin Flush Mechanism is a high-performance, universal toilet repair solution engineered for the replacement of aging or inefficient internal cistern components. Designed to fit most standard ceramic and plastic toilet tanks, this dual-flush system is a critical tool for water conservation, allowing for a choice between a “reduced” or “full” flush volume to significantly lower domestic water consumption.

Technical Engineering and Design

• Universal Telescopic Calibration: The mechanism features a telescopic overflow pipe that can be adjusted in height without cutting. This ensures compatibility with a vast range of cistern depths, from low-profile modern tanks to older, deeper ceramic models.
• Dual-Flush Technology: Equipped with a high-visibility chrome push-button, the system allows the user to select between a small flush (typically 3 liters) and a full flush (6 liters). This mechanical choice is a foundational component for modern green-building standards and drought-resistant households.
• Easy-Maintenance “Quarter-Turn” Logic: The valve body is designed with a bayonet-style locking system. This allows the main housing to be removed from the base with a simple quarter-turn, enabling the replacement of the silicone sealing washer without disconnecting the cistern from the wall or the bowl.
• Adjustable Small Flush Float: The internal small-flush float can be moved vertically to fine-tune the water volume for the reduced flush, ensuring that the toilet clears effectively while using the minimum amount of water possible.

Material Integrity and Reliability

• High-Grade Polymer Construction: Manufactured from reinforced, UV-stabilized ABS and polypropylene, the mechanism is resistant to the corrosive effects of hard water and common cistern cleaning chemicals. It will not rust, scale, or corrode over time.
• Long-Life Silicone Seal: The unit comes standard with a high-performance silicone sealing washer. Silicone remains pliable longer than traditional rubber, resisting the “blistering” and hardening caused by chlorine in municipal water supplies, ensuring a bubble-tight seal for years.
• Cable-Operated Flexibility: Unlike rigid-linkage systems that require precise alignment, many Wirquin models utilize a flexible cable to connect the push-button to the flush valve. This allows the button to be mounted on the top, front, or side of the cistern.

Operational Applications

• Residential Retrofitting: An ideal “all-in-one” kit for homeowners looking to upgrade an old-fashioned single-flush siphon to a modern, water-saving dual-flush system.
• Commercial Facility Management: The robust construction and ease of maintenance make this the industry standard for office blocks, schools, and shopping centers where high-frequency use demands reliable performance.
• Plumbing Maintenance and Repair: A staple for any professional plumbing inventory, as its universal fitment reduces the need to carry multiple brand-specific replacement parts.

Technical Specifications

• Button Aperture: Designed to fit standard 38mm to 45mm holes in cistern lids.
• Outlet Diameter: Standard 2-inch (50mm) BSP outlet, compatible with most close-coupled and low-level toilet pans.
• Certification: Often WRAS-approved or compliant with international water-saving standards, ensuring the mechanism meets rigorous testing for mechanical endurance and hydraulic efficiency.

Designed for rapid installation and long-term reliability, the Wirquin Flush Mechanism is an essential component for efficient water management. Its combination of universal adjustability and precision dual-flush control provides a dependable, low-maintenance solution for any modern bathroom environment.
