Compact cistern Koło Nova Pro 6L M34010000 — 6-litre toilet flush unit

The Koło Nova Pro 6L compact cistern is a fixed-volume toilet flush unit intended for use with close-coupled toilets. Designed to deliver a consistent 6-litre flush, this cistern fits standard close-coupled pan and wall mounting arrangements and is suitable for both replacement and new-install applications in domestic and light commercial bathrooms. Its compact form factor is intended to save space while providing a reliable single-flush operation.

Advantages

The cistern offers a straightforward, single-volume 6 L flush that simplifies installation and maintenance by avoiding dual-flush mechanisms. Its compact dimensions make it suitable where space is limited, and the product is compatible with commonly used close-coupled fittings. The fixed-flush design reduces the number of moving parts compared with multi-mode cisterns, which can translate to fewer points of failure and easier servicing.

Suitable for

• Replacement of existing close-coupled toilet cisterns that require a 6-litre flush volume.
• New installations where a compact, space-saving cistern is needed for a close-coupled pan.
• Domestic bathrooms and light commercial washrooms with standard plumbing connections.

When it may not be suitable

This fixed 6 L cistern is not suitable where water-saving dual-flush functionality is required or mandated by local conservation regulations. It may also be unsuitable for systems that require concealed or in-wall cisterns, or for toilet pans designed specifically for different flush volumes or mounting interfaces.

Key specifications

• Flush volume: fixed 6 litres
• Type: compact close-coupled cistern for toilet pan
• Mounting: designed for standard close-coupled pan and wall fittings
• Intended use: replacement or new-install for domestic and light commercial bathrooms
• Operation: single flush mechanism (fixed volume)

How to use

Install the compact cistern on a compatible close-coupled toilet pan following the manufacturer’s installation guidelines and local plumbing codes. Connect the water supply and adjust the inlet valve and flush mechanism as required to ensure a proper 6-litre fill and reliable flush operation. After installation, test the unit by performing several flush cycles and check for leaks at the supply and pan connections. Regular inspection and occasional servicing of the inlet valve and seals will help maintain consistent performance.

What to consider before purchase

• Confirm that your toilet pan is compatible with a compact close-coupled cistern and supports a 6 L flush volume.
• Verify space and mounting conditions to ensure the compact form factor fits the installation location.
• Check local regulations or building codes for required water-saving standards or minimum/maximum flush volumes.
• Ensure the wall and pan fixings match common close-coupled mounting arrangements or that appropriate adapters are available.

Usage recommendations

For reliable operation, use the cistern on a compatible close-coupled pan and perform periodic checks of the inlet valve and seals. If water saving or dual-flush operation is required, consider an alternative model with multi-mode flushing.
