Fill valve SIAMP BRIO 751-3/8P side inlet 3/8" plastic

SIAMP BRIO 751-3/8P side inlet fill valve is a compact plastic cistern valve designed to control water supply and automatic refill in toilet cisterns. The valve features a 3/8" side inlet connection and a plastic body that provides corrosion resistance and lightweight installation. It is intended for standard domestic toilet installations where a reliable, space-saving fill mechanism is required.

Advantages

The plastic construction of this fill valve ensures resistance to corrosion and mineral buildup in typical household water conditions, while keeping overall weight low for easy handling. The side inlet 3/8" connection provides compatibility with common water supply fittings and simplifies retrofitting into existing cisterns. Its compact profile is suitable for cisterns with limited internal space and reduces the need for structural adjustments during replacement or installation.

Suitable for

• Standard domestic toilet cisterns with a side inlet connection
• Replacement of worn or leaking fill valves in household bathrooms
• Compact or low-profile cisterns where space inside the tank is limited
• Installations requiring a 3/8" water supply connection

Key specifications

• Connection type: side inlet, 3/8"
• Material: plastic body and internal components suited for freshwater supply
• Application: toilet cistern water refill and level control
• Design: compact, space-saving profile for installation in confined cisterns

How to use

Shut off the water supply before removing the old valve. Drain the cistern and disconnect the incoming water line from the side inlet. Fit the SIAMP BRIO 751-3/8P into the cistern according to the cistern manufacturer's instructions, secure the connection to the 3/8" supply line, and turn the water back on. Adjust the float or fill level mechanism as required to achieve the correct water level and check for leaks. Test the fill and shutoff operation by flushing the toilet several times and observing consistent refill and shutoff behavior.

Usage recommendations

Use the valve with freshwater supply systems and regular household water pressure within standard domestic ranges. Periodic inspection and cleaning of the valve and inlet filter, if present, will help maintain reliable operation. If the water supply has high mineral content, consider routine descaling to prevent reduced performance.
