replace a siphon with a close coupled

[littlelegs]

can I buy the parts to fit an existing cistern or do I need to purchase an assembled cistern?
Any advice appreciated

 

[littlelegs]

That might even be the wrong question!!!!
The mechanism inside the existing cistern is almost solid with limescale and it takes several goes to flush so I want to replace the internals .......

If it's a syphon more likely the diaphragms split if it takes a few good hard pulls to flush.

If all else fails RTFM - I have a close coupled system with a Siphon, ballcock and flap valve - all nicely coated with crust.

I would like to replace it with "modern , efficient" alternative.

Fitting a flat push button might be problematic as the current handle sits on a curve of the cistern casing.


That's better .........

you can't have a syphon & flap valve.

I would like to replace it with "modern , efficient" alternative.

Don't bother modern flush valves are cr*p & have reduced water flush.

hmmm , the diagram I have shows a siphon and inside are a "flap valve" that sits on top of perforated plate - perhaps the description of the parts is wrong

Your talking about this ?
Thats the syphon diaphragm.

Fit a Fluidmaster flapper valve. Simplistic in its design, easy to maintain, adjustable dual flush.
This model uses your existing handle:

is this just a like for like replacement or do I need additional bits?
Handle connects to the chain link?

 

[Charnwood]

The Screwfix picture is not that good, so here's one from Fluidmaster's own website:

The handle fits into this contraption designed to stop the handle being pushed down too far and causing the link arm to hit the cistern lid.

No further bits required. Remove syphon, fit flapper valve.

[littlelegs]

is it worth installing a fluidmaster 400 uk bottom inlet float valve as well?
I mean - it's only a tenner........

 

[Charnwood]

Go for it.

If you are going to do this it might be a good idea to fit a new rubber donut washer as they don't always reseat properly.

there's Klingons on the starboard bow too - the securing bolts are all rusted as well so I may as well just go for it and do a proper job - many thanks for the links to the new kit !!!!!
