Hi. I've had a Geberit Duofix 112cm installed with the Sigma 12cm cistern, flowing into the Bauhaus Pier compact WC. On either flush - smaller or bigger - the water often overflows the rim of the toilet out onto the floor.
Can anything be done to reduce the flow from the cistern?
My dealer has mentioned a cup device, which I believe is "Cup for flush volume 4.5 / 3 litres, for Geberit Sigma concealed cistern 12 cm", part number 241.894.00.1. Geberit's website is a bit lacking in explaining exactly what this does, but I believe it reduces the flush volume from 5.8 / 3 litres to 4.5 / 3 litres. But if this merely reduces the larger flush volume and doesn't also reduce the flow, it won't help, since the existing 3 litre flush goes all over the floor. Any thoughts on whether this would help? Or whether there are other solutions? Currently I think the only solution is to replace the pan.
Thanks for any ideas!
