Fill Valve CERSANIT NF AQUA 40/50 with Metal Tip — Toilet/Cistern Fill Valve

The CERSANIT NF AQUA 40/50 fill valve with metal tip is designed for controlling the water inlet and maintaining the correct fill level in toilet cisterns. Compatible with cisterns and installations built to NF AQUA 40 or 50 dimensions, this component is suitable for replacing worn or faulty fill valves or for use in new installations. The metal tip provides improved durability at the point of contact with the float or inlet mechanism and is intended for applications where a stronger, longer-lasting connection is required.

How to use

Shut off the water supply to the cistern and flush to empty the tank before beginning installation. Remove the existing fill valve according to the cistern manufacturer’s instructions, then fit the CERSANIT NF AQUA 40/50 fill valve into the inlet opening, ensuring proper alignment with the cistern’s mounting points and seals. Adjust the valve height if necessary to match the cistern fill level specification and reconnect the water supply. Observe several fill cycles to confirm correct operation and adjust the float or filling height to achieve the desired water level.

Usage recommendations

Use appropriate seals and check washers during installation to prevent leaks. Inspect the metal tip and sealing surfaces periodically for signs of wear or mineral buildup, and clean or replace components as needed to maintain reliable performance. Follow local plumbing codes and manufacturer guidance when installing or servicing the fill valve.
