Twyfords toilet not flushing

[Paulintheuk]

Hello

My Twyfords (A033?) wont flush properly. You have to push the handle down 6-10 times before it flushes, I wonder if someone can help me ?

Sounds like the diaphragm has had it's day. This is a small rectangle of thin plastic inside the syphon - which is the large green device in the middle of the picture. It's a pain to replace, as it means removing the syphon to get at the innards.

If it were me, I would take the opportunity to replace the syphon itself with a Dudley Duoflush - a bit more expensive than a regular syphon; but any future diaphragm replacement can be carried out much more easily. Another added benefit is that the Dudley product enables water-saving, as it provides both a half-flush for your no.1 jobs, and a full flush for your no. 2s.

They're available on ebay, such as here: http://cgi.ebay.co.uk/DUDLEY-TURBO-...DIY_Materials_Plumbing_MJ&hash=item563dd13bbb

Water level is low.Adjust the white screw on the ball valve assy to raise the water level to the mark on the cistern inner wall then give it a try.

If in doubt - don't. You can give yourself huge problems if you are not sure, especially if this is your only bog.

Call in a professional.

I agree with mysteryman's advice - if you don't feel confident, probably best to get someone in.

If however you do feel like giving it a go, the steps are these:

1. Shut off water supply to cistern, and flush it
2. Bale out remaining water
3. Underneath the cistern, you'll find a large hexagonal nut that secures the flush pipe - undo it using a large spanner or waterpump pliers
4. You'll then see a further large hexagonal nut which secures the syphon in place. Undo it, and be prepared to catch any remaining water with cloths
5. Inside the cistern, remove the c-link (a short, bent piece of wire that connects the flush handle to the syphon's lift arm)
6. The syphon should now lift out - push the lift arm from the top of the syphon, and it will emerge from the bottom
7. You will then see the diaphragm - a little piece of plastic sheet about 4" x 3" (it will probably be torn, or folded, or otherwise unserviceable)
8. Cut yourself a new piece of plastic to replace it
9. Put it all back together, in reverse order to the above

Good luck if you do decide to have a go!
