How can I get to the flap valve?
I need to replace the valve inside the siphon. All the sites I've read, and my DIY book, say to release the siphon by releasing the nut under the cistern or on the flush pipe, but this is a coupled unit and I can't find any nuts under the cistern - how do I release the siphon? Don't know what make it is.
