Fill Valve CERSANIT K99-0011 1/2" Side Inlet for Toilet Cisterns

CERSANIT fill valve K99-0011 is a side-inlet 1/2" refill mechanism designed for toilet cisterns. It controls the incoming water flow to restore and maintain the correct cistern water level and prevents overflow by shutting off the supply when the set level is reached. The valve is intended for use in standard household cisterns with a 1/2" side connection and can be used as a direct replacement for compatible inlet fittings during installation or repair of sanitary systems.

Advantages

The side-inlet configuration allows flexible positioning in cisterns with lateral supply lines, providing a compact solution where top-entry valves are unsuitable. Constructed to deliver stable water level regulation, the valve reduces the risk of continuous running or flooding by delivering a precise shut-off at the preset level. Compatibility with common 1/2" fittings simplifies replacement and installation in many domestic toilet cisterns, and the design supports routine maintenance without requiring extensive disassembly.

Suitable for

• Replacement of side-inlet fill valves in household toilet cisterns with 1/2" connection
• Installation during bathroom renovations where lateral water supply is used
• Maintenance or repair of cisterns that display continuous filling or overflow issues
• Use in standard domestic sanitary systems requiring a reliable inlet shut-off

Key specifications

• Connection type: side inlet, compatible with 1/2" supply fittings
• Function: refill valve with automatic shut-off at set water level
• Application: toilet cisterns for domestic sanitary systems
• Mounting: side-mounted installation inside cistern
• Operation: float-actuated mechanism for level control

How to use

Shut off the water supply before removing the old valve. Drain the cistern and access the side inlet area. Remove the existing valve and fit the CERSANIT side-inlet fill valve into the 1/2" connection, ensuring a secure seal. Reconnect the water supply and open it slowly to check for leaks. Adjust the float or level-setting mechanism if necessary to obtain the desired fill height. Observe the first few fill cycles to confirm proper shut-off operation and absence of continuous flow.

Usage recommendations

Use compatible sealing tape or washers on threaded connections to ensure leak-free installation. If significant lime scale or debris is present in supply lines, flush the inlet before installation to reduce the risk of valve malfunction. For reliable long-term performance, inspect the valve periodically and replace worn seals.
