## Long description

SIAMP BRIO 573 is a dual-flush toilet valve designed for cistern replacement and retrofit in installations requiring 3/6 L operation. The valve provides controlled water inlet and discharge to ensure efficient flushing while reducing water consumption. It is intended for use in standard cisterns where a reliable dual-flush mechanism is needed for domestic and light commercial toilets.
Advantages
The BRIO 573 combines a simple mechanical design with adjustable settings for flush volume and overflow control, enabling dependable operation and reduced maintenance. Its dual-flush function supports efficient water use by offering separate small and large flush options. The valve is compatible with common cistern types and materials, facilitating straightforward replacement without extensive modifications.
Suitable for
 Domestic toilet cistern replacements
 Small commercial restroom retrofits
 Projects requiring a 3/6 L dual-flush mechanism

Key specifications
 Dual-flush operation with adjustable small (≈3 L) and full (≈6 L) flush volumes
 Designed for gravity-fed cisterns
 Mechanical valve construction for durability and ease of service
 Adjustable fill and overflow settings to suit different cistern heights and water pressures
 Materials suitable for contact with potable water
How to use
Shut off the water supply and drain the cistern before removing the existing valve. Install the BRIO 573 according to the cistern manufacturer’s access points and align the valve body with the inlet and flush mechanism. Reconnect the water supply and adjust the fill level and flush volumes as needed to achieve the desired 3/6 L performance. Test both flush options to confirm proper sealing and operation, and check for leaks around connections.
Usage recommendations
Use the valve in cisterns that match the specified dual-flush configuration and observe local plumbing codes. Periodic inspection for wear, mineral buildup, and seal condition will extend service life. If water pressure or cistern geometry differs significantly from standard conditions, consult installation guidance or a qualified plumber to ensure correct performance.
