Toilet wont flush properly All aspects of plumbing questions and answers, help, tips and information

[SIMON M]

I think the problem is the flush diagphragm, i have a guy looking at it but he says because it is close coupled cistern he has to take the cistern off the wall (gulp) to get the diagphram changed. The unit doesn't seem to be bolted in to the cistern but stuck in with what looks like chewing gum.

Does the cistern really have to be removed? or will it just bump the price up?

Thanks.

Hi, if the siphon diaphragm needs to be changed and the suite is close coupled, then the cistern does need to be removed. If all goes well, this is a simple job. BUT, I would recommend changing the connector set at the same time ( £4.98 from B&Q ). Instead of simply changing the membrane, or just the siphon, why not change the whole siphon system for a rubber lifting-valve and push-button arrangement ( £16.00 from focus or £19.98 from B&Q ). This means you never have the problem again, and ( if you don't already have one ) include an internal overflow.
