Two flush volumes are available: Full Flush: For solid waste – typically 6 litres Reduced Flush: For liquid waste – typically 3–4 litres This dual flush system can reduce water consumption by up to 60% compared to older single-flush cisterns, lowering utility bills and reducing environmental impact.

No separate button purchase is required, unlike some other Adagio cistern models. What is the difference between side fill and bottom fill? The side fill inlet (this model, 39054000) accepts the water supply connection from the left, right, or back of the cistern — useful for furniture installations, retrofits, or where pipework enters from the side. The bottom fill model (39053000) connects from below, which is standard for new builds with floor-level pipework. Flush performance is identical on both. What wall thickness is this suitable for? This cistern is designed for walls between 18mm and 24mm thick, covering standard stud wall and bathroom furniture panel constructions. What is EcoJoy technology? EcoJoy is Grohe’s dual flush system delivering a 6 litre full flush and a 3 litre half flush. Choosing the half flush for liquid waste reduces water consumption by up to 50% compared to older single-flush cisterns, lowering utility bills and reducing environmental impact without compromising flush performance. What is Acoustic Group I? Acoustic Group I is the quietest classification for cistern fill noise under European standards. It means the cistern refills quietly after flushing — particularly important for ensuites, apartments, and bathrooms adjacent to bedrooms. What is the minimum water pressure required? A minimum static pressure of 0.2 bar is required, making this cistern compatible with most UK water supplies including properties with lower pressure. Can I order if the item shows as out of stock?

This configuration keeps all plumbing hidden and creates a cleaner, more streamlined appearance compared to side or top inlet cisterns. Bottom inlet is particularly popular for wall-hung toilet installations where all pipework is concealed behind the wall. Dual Flush Water Saving The 6/4 litre dual flush system provides two flush options: Full Flush (6L): For solid waste – uses 6 litres per flush Half Flush (4L): For liquid waste – uses only 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.

The compact design is ideal for: Small bathrooms and cloakrooms Stud wall installations (100mm or 150mm studs) Wall-hung toilet installations Back-to-wall WC units Furniture-mounted toilets Anti-Condensation Sleeve The included polystyrene sleeve insulates the cistern, preventing condensation from forming on the cold water tank. This is particularly important in concealed installations where condensation could damage plasterboard, cause mould growth, or create damp patches on walls. The sleeve maintains a barrier between the cold cistern and the warmer room air. Applications & Use Cases Wall-Hung Toilets: Complete concealed cistern solution Back-to-Wall WCs: Hidden cistern behind furniture or paneling Bathroom Renovations: Modern concealed installations New Builds: Contemporary bathroom designs Commercial Installations: Hotels, offices, restaurants, care facilities Cloakrooms: Space-saving compact installations Installation Requirements Requires a stud wall or supporting framework (minimum 100mm depth, 150mm recommended). The cistern is mounted to the wall using the supplied brackets. Bottom inlet water supply (15mm) should be positioned to connect from below. The adjustable flush pipe connects to the WC pan and can be cut to the required length. Professional installation recommended to ensure proper support, waterproofing, and compliance with building regulations. Push Button Positioning The chrome push button can be positioned on either the left or right side of the WC unit, providing installation flexibility to suit your bathroom layout, user preferences, or accessibility requirements. This is particularly useful when the toilet is positioned near a wall or obstacle that would restrict access to one side. Compatible Push Buttons While a chrome push button is included, this cistern is also compatible with the following alternative push buttons for different aesthetic preferences: BGBP106323 – Brushed Brass finish BGBP106324 – Matt Black finish BGBP109030 – Brushed Bronze finish BGBP106322 – White finish Note: This cistern is NOT compatible with flush plates. Only push button actuators are supported.

Once activated, the flush completes its full 6-litre cycle regardless of button release, ensuring thorough waste removal every time. This prevents partial flushes that can lead to hygiene issues and reduces the need for multiple flushes, ultimately saving water despite being a single-flush system. Side Fill Configuration: Installation Flexibility: The side fill design allows water supply connection from the left, right, or back of the cistern. This is particularly valuable for commercial installations, retrofit projects, furniture-mounted WC units, and situations where existing pipework positioning dictates inlet location. The flexible connection options simplify plumbing and reduce installation time. Grohe Starlight Chrome Finish: The Grohe Starlight chrome finish delivers exceptional durability through multiple layers of premium chrome plating. This creates a finish that resists scratching, tarnishing, and corrosion whilst maintaining its mirror-like lustre. Easy to clean and maintain, Starlight chrome is engineered to withstand demanding bathroom environments, making it ideal for both commercial and residential applications. Technical Advantages: Commercial Grade Construction: Built to withstand high-frequency use, this cistern is ideal for commercial washrooms, public facilities, offices, and high-traffic residential bathrooms.

Low Pressure Compatibility: With a minimum recommended static pressure of just 0.2 bar, this cistern works reliably even in properties with lower water pressure, ensuring consistent flush performance across all installations. ABS Flush Pipe: The included ABS (Acrylonitrile Butadiene Styrene) flush pipe offers superior durability compared to standard plastic pipes. Resistant to impact, chemicals, and temperature variations, the 180mm × 320mm pipe ensures reliable connection between cistern and WC pan. Perfect For: Commercial washroom installations Public facilities and offices High-traffic residential bathrooms Back-to-wall toilet systems Furniture-mounted WC units Retrofit projects with side pipework Hotels and hospitality installations Schools and educational facilities Healthcare and care home bathrooms Applications requiring non-interruptible flush Single Flush vs Dual Flush: This 6-litre single flush model is ideal for commercial applications where consistent flush volume is required, or where simplicity and reliability are priorities.
