Fill valve SIAMP BRIO 751-1/2P — side inlet 1/2" plastic

SIAMP BRIO 751-1/2P is a side-inlet plastic fill valve with a 1/2" connection designed for toilet cisterns. It controls the water supply to the tank and refills the cistern after flushing. The valve is intended for installations with a lateral water feed and is compatible with common cistern assemblies used in residential and commercial bathrooms.

Advantages

The fill valve offers stable inlet regulation and straightforward mechanical adjustment for setting the desired water level. Its plastic construction provides corrosion resistance and reduces the risk of mineral buildup on exposed components. The side-inlet design simplifies installation where the water supply enters from the cistern side, and the 1/2" connection matches standard plumbing fittings, facilitating replacement or upgrade of existing valves.

Suitable for

• Residential toilet cisterns with lateral water feed
• Commercial restroom installations requiring reliable refill control
• Retrofit projects replacing worn or leaking side-inlet valves
• Standard plumbing systems using a 1/2" connection

Key specifications

• Connection type: side inlet
• Connection size: 1/2" thread
• Material: plastic body and components
• Adjustment: mechanical water level regulation
• Application: toilet cistern refill valve

How to use

Shut off the water supply before removing the old valve. Position the SIAMP BRIO 751-1/2P into the cistern side inlet and secure the 1/2" threaded connection according to the cistern manufacturer’s instructions, ensuring a watertight seal. Restore water supply and allow the cistern to fill, then adjust the mechanical regulator to set the correct fill level and stop position. Verify there are no leaks and that the valve reliably shuts off after filling.

Usage recommendations

Install with compatible seals or washers and tighten connections hand-tight plus a small additional turn with a wrench; avoid over-tightening plastic threads. Periodically inspect the valve for mineral deposits or wear and clean or replace components as needed to maintain reliable operation.
