My toilet won't flush?

I have just replaced the diaphram in my toilet in 15mins,if the syphon will split in the cistern it is a easy repair,i cut a piece of plastic envelope to make a new one it now works perfect,when u take the cistern lid off av a look at thesyphon ,if it has a bend at the top with plastic connectors u can unscrew both sides then pull out the syphon,the repair is then straight forward if notu will need to take off the cistern which is a lot more difficult

I recently replaced the diaphragm in my toilet and it was a piece of cake. I detached the syphon, opened it up and popped down B&Q (Warehouse) picked one up for £1.28 (incl. Doughnut washer)
What you tend to find is that a lot of home DIY places (eg B&Q, Homebase etc) will try and flog you a complete solution which costs about £30! and Home DIY stores keep very low stocks of individual components. However failing this you can always visit a plumbers merchant!
I admit I was lucky as not all syphons come apart so easily as mine did but to say that its a difficult job without more information is a little hasty at best and at worst misleading! This surely defeats the object of forums like this one. "I suggest that you bite the bullet and call a plumber....my telephone number is" ....yeah right!

The diaphragm that lifts the water up into the siphon is worn or deteriorated. To replace a diaphragm you need to take the whole siphon out. This is not a simple job, I suggest that you bite the bullet and phone a plumber
