Leaking Gerberit concealed cistern

[mervingiblet]

I had a Gerberit concealed cistern fitted around 7 years ago in the downstairs loo. It recently started leaking from the flush bend. I thought it would be a case of just tightening the connection at the cistern end but there is nothing to tighten.

I've tried going down the plumbers mate route but that didn't work.

Can anyone please help?
Thanks.

If it's leaking from the cistern/flush pipe union then there are usually a couple of 'O' rings which may need replacing. If it's leaking form the lush pipe/pan end (more likely) then the internal flush cone probably needs replacing.

This is an old thread, but it's all I could find to help me with a geberit leak under the cistern... only after using the flush.
I removed the snap fit clip and rubber seal and cleaned both. Both then replaced in the same order, although tricky to set them in good alignment. It takes a bit of force to get the clip back in. The clip needs to be fully positioned within the rim of its surrounding part of the cistern.
All good now
