CERSANIT compact toilet cistern 6L K02-012, low water consumption, for close-coupled toilets

CERSANIT compact toilet cistern 6L K02-012 is a low-consumption cistern designed for close-coupled toilet installations. With a fixed 6-litre flush volume, it replaces older high-capacity tanks to reduce water use while remaining compatible with standard compact toilet pans and common mounting fittings. The unit is intended for domestic and light commercial bathrooms where a reliable, space-efficient cistern is required and fits directly onto the toilet bowl in close-coupled configurations.

Advantages

The cistern offers a consistent 6 L flush that lowers water consumption compared with larger-capacity models and helps achieve basic water-saving targets in households and small businesses. Its compact design reduces the overall depth of the toilet assembly, allowing installation in tighter bathroom layouts. Compatibility with standard close-coupled fittings simplifies replacement of existing cisterns, and the single-volume mechanism provides straightforward, low-maintenance operation.

Suitable for

• Replacing older high-capacity cisterns in domestic bathrooms
• Installation in compact or small bathrooms where space is limited
• Close-coupled toilet setups with standard bowl connections
• Light commercial washrooms with basic water-saving requirements

Key specifications

• Flush volume: fixed 6 litres
• Type: compact cistern for close-coupled toilets
• Installation position: mounted directly on the toilet bowl (close-coupled)
• Intended use: domestic and light commercial bathrooms
• Operation: single-volume flush mechanism

How to use

Install the cistern using the appropriate fittings for a close-coupled toilet, ensuring a secure connection between the cistern outlet and the toilet pan inlet. Connect the water supply according to local plumbing standards and check for leaks. Operation is straightforward: activate the flush using the cistern's actuating mechanism to release the fixed 6 L volume. Periodically inspect the internal valve and seals for wear and clean as needed to maintain reliable performance.

Usage recommendations

For optimal performance, use the cistern as a direct replacement for similarly configured close-coupled bowls and verify that the bowl inlet aligns with the cistern outlet. Regularly check seals and the fill/flush mechanism for mineral buildup in hard-water areas and perform preventative maintenance to avoid leaks. If a dual-flush or variable-volume solution is required, consider evaluating a different model designed for adjustable water consumption.
