I believe this website will answer your question: http://www.sustainablesolutions.com/video.php
Click on the Caroma Dual Flush Valve Maintenance near the bottom of the page. I have just purchased a Caroma and believe this is the answer to my leakage from tank to bowl problem. I will be calling them for a replacement of this rubber gasket.
