Dual Flush Water Saving
The dual flush system provides two flush options for maximum water efficiency:
-
Full Flush: For solid waste – typically 6 litres per flush
-
Half Flush: For liquid waste – typically 3-4 litres per flush
Compared to older single-flush cisterns (9-13 litres), this dual flush system can reduce water consumption by up to 60%, saving money on water bills and helping the environment. For a family of four, this can save approximately 20,000 litres of water annually, translating to significant cost savings over the cistern's lifetime.
Front & Top Access Benefits
This cistern offers both front and top access for servicing and maintenance:
-
Front Access: Service the cistern through the push button opening – ideal for installations where top access is restricted by shelving, cabinets, or low ceilings
-
Top Access: Full access from above for major servicing or component replacement – useful during installation or for comprehensive maintenance
This dual-access design provides maximum flexibility for different installation scenarios and makes future maintenance easier, reducing service time and costs.
WRAS Approval
The flushing valve and all water fittings are WRAS (Water Regulations Advisory Scheme) approved, confirming they meet UK water supply regulations. This ensures the cistern operates efficiently, won't contaminate drinking water, and complies with building regulations requirements for new installations and renovations. WRAS approval is essential for professional installations and provides assurance of quality and reliability.

Professional installation recommended to ensure proper support, waterproofing, and compliance with building regulations.
Chrome Push Button
The included chrome push button provides a clean, contemporary finish that coordinates with modern bathroom fixtures and fittings. The dual flush mechanism is clearly marked for easy operation, with separate buttons or zones for full and half flush activation. The chrome finish is durable, corrosion-resistant, and easy to clean.
Concealed Cistern Advantages
Concealed cisterns offer several benefits over traditional exposed cisterns:

-
Modern Aesthetics: Clean, minimalist appearance with only the push button visible
-
Easier Cleaning: Wall-hung toilets allow easy floor cleaning underneath
-
Flexible Positioning: WC pan height can be adjusted during installation

Water Efficiency & Building Regulations
This dual flush cistern meets current UK building regulations requirements for water efficiency and helps achieve water efficiency credits in environmental assessment schemes. The water savings translate to lower utility bills and reduced environmental impact, making it an excellent choice for eco-conscious installations and developments seeking sustainability credentials.
Maintenance & Servicing
The dual-access design makes maintenance straightforward. Most routine servicing (valve adjustments, seal replacements) can be performed through the front push button opening without removing wall panels. The WRAS-approved components are designed for long-lasting, reliable operation with minimal maintenance required. Replacement parts are readily available if needed.
Installation Tips
- Ensure adequate wall support – use appropriate fixings for your wall type
- Check water pressure meets minimum requirements
- Position cistern at correct height for your WC pan
- Ensure push button will be accessible after wall finishing
- Test for leaks before closing up the wall cavity
- Keep access to isolation valve for future maintenance
Compatible WC Types
This concealed cistern is compatible with:
- Wall-hung WC pans (suspended toilets)
- Back-to-wall WC pans (floor-standing with concealed cistern)
