## Long description

Sealing gasket for flush valve for CERSANIT concealed cisterns AQUA/ASTRA/TARGET/LEON is a spare rubber sealing element designed to restore watertight connection between the flush valve and the cistern body in compatible in-wall WC systems. This replacement gasket is intended for maintenance and repair of concealed cisterns where a worn or damaged seal causes leakage, reduced flushing performance, or the need to dismantle the valve for service. The gasket fits models from the AQUA, ASTRA, TARGET and LEON installation ranges and provides a reliable seal when installed correctly.
Advantages
The gasket is made from elastomer material formulated for contact with potable water and for resistance to compression set, ensuring long service life under typical cistern operating conditions. Its construction offers a secure, leak-resistant fit at the valve connection and is dimensioned to match the mating surfaces of the specified CERSANIT concealed cisterns. Using the correct spare gasket reduces the risk of water damage from slow leaks and helps restore normal flushing operation without the need for full unit replacement.

How to use
Switch off the water supply and drain the cistern before starting work. Access the flush valve by removing the cistern service panel or actuator according to the installation instructions for your CERSANIT frame. Remove the old gasket from the valve connection, clean mating surfaces to remove deposits or debris, and inspect the valve seat for damage.

Reassemble the valve and actuator, restore the water supply and perform test flushes to check for leaks and correct operation.
Usage recommendations
Use the gasket only with the specified CERSANIT concealed cistern ranges and replace any damaged or deformed seals promptly to prevent continuous leakage. If leaks persist after gasket replacement, inspect the valve components and cistern body for wear or damage and consult CERSANIT service documentation or a qualified plumber.
