Filling valve for concealed frame CERSANIT Aqua/Astra/Target/Leon (K99-0067)

Replacement filling valve compatible with CERSANIT concealed frames from the Aqua, Astra, Target and Leon series. This valve is designed to control the water inlet to a concealed cistern used in wall-hung toilet installations, restoring correct filling levels after each flush. It is intended for maintenance or repair of compatible in-wall frames and concealed WC systems where the original filling mechanism is worn, leaking, or malfunctioning.

Advantages

The filling valve offers reliable regulation of inlet flow and consistent cistern filling to maintain proper flush performance. Its design is suitable for concealed installation and enables straightforward replacement without modifying the frame structure. The valve reduces the risk of overfilling and continuous running, and is made to match the functional requirements of the specified CERSANIT in-wall systems.

Suitable for

• Repair of CERSANIT concealed cisterns in Aqua, Astra, Target and Leon series
• Replacement of worn or leaking filling valves in wall-hung toilet systems
• Maintenance work on in-wall WC systems to restore correct water inlet control
• Plumbing upgrades where original valve performance is unsatisfactory

Key specifications

• Function: automatic cistern water inlet control (filling valve)
• Compatibility: designed for concealed in-wall cisterns of the specified series
• Installation location: interior of concealed cistern/frame
• Operation: float-controlled mechanism for level regulation
• Material: corrosion-resistant components suitable for potable water systems

How to use

Before replacement, shut off the water supply to the cistern and drain the tank by flushing. Open the access panel or remove the actuator plate to reach the existing filling valve. Unscrew or unclip the old valve according to the frame design and remove it from the inlet connection. Install the replacement valve into the inlet seat, ensuring correct alignment and a secure seal on the water supply connection. Reconnect the supply, restore the water, and observe the filling process to confirm the float mechanism shuts off at the required level. Replace the actuator plate or access panel after testing.

Usage recommendations

Use compatible seals and follow manufacturer torque recommendations when tightening connections to avoid leaks. If uncertain about frame compatibility or if structural access is limited, consult a qualified plumber. Periodic inspection and cleaning of the valve and inlet filter will extend service life and maintain reliable cistern filling.
