Flush valve Inter-Sano model for 3/6 L cisterns

Flush valve Inter-Sano model for 3/6 L cisterns is a replacement valve designed for dual-flush toilet cisterns that offer 3 and 6 litre flush options. The unit controls water release and refill cycles to ensure proper flushing performance and reliable sealing of the cistern outlet. It is intended as a direct functional replacement in compatible residential and commercial cisterns and aids in restoring correct operation of the flush mechanism.

Advantages

This Inter-Sano flush valve provides stable water release and consistent refill control for dual-flush systems with 3 L and 6 L settings. The valve is built to resist common wear factors found in toilet cisterns, maintaining a watertight seal and reducing the risk of leaks when installed correctly. Its straightforward design allows for easier servicing and replacement of worn components compared with complex integrated mechanisms.

Suitable for

• Replacement of worn or leaking dual-flush cistern valves with 3/6 L capacity
• Repair and maintenance of residential toilet cisterns
• Upgrading or restoring functionality in commercial washroom cisterns compatible with 3/6 L flush systems

Key specifications

• Dual-flush control: offers two discharge volumes (3 litres and 6 litres)
• Designed for use in standard toilet cisterns with compatible mounting and outlet dimensions
• Material: corrosion-resistant components suitable for potable water systems
• Sealing: designed to provide a reliable watertight seal at the cistern outlet
• Serviceability: modular parts allow for straightforward inspection and replacement of wear items

How to use

Turn off the water supply to the cistern and flush to empty remaining water before beginning installation. Remove the cistern lid and take out the existing valve assembly following manufacturer guidance or standard cistern service procedures. Fit the Inter-Sano flush valve into the outlet opening, ensuring the sealing surfaces are clean and properly seated. Reconnect the water supply, allow the tank to refill, and test both the 3 L and 6 L flush settings to confirm correct operation and leak-free sealing. Adjustments may be required to align the actuator or float mechanism according to the cistern design.

Usage recommendations

Use appropriate tools and observe safety precautions when servicing the cistern. If the cistern or flush mechanism shows incompatible mounting dimensions or persistent leaks after installation, consult a qualified plumber or the cistern manufacturer for compatibility checks and professional installation.
