I suspect the diagphram is on its way out as flushing getting less
efficient.

How do I know which size/type to purchase without dismantling the mechanism.

When I do flush there still remains about 3 to 4 inches of water in the
bottom of the cistern, is this normal?

As a comment I would suggest you slide the lifting arm forwards so it exerts
a direct lift upwards and doesn't strain stuff. Some water will remain as
once the siphon draws air in the column of water will collapse back into the
cistern.

The ones I've seen in B&Q etc are intended to be cut to size - use the
old one as a template - though TBH any bit of relatively heavy polythene
sheeting will do just as well as a purpose-bought item.

Can't really see from the photo, but that sounds a bit more than
'normal' - you sure you aren't flushing in 'eco' mode or something?

I dont think there are different flushing modes, just a cheapo toilet.

I just measured and there is 3 inches of water remains in the bottom of
cistern when flushing.

I have now religned the `pull lever` part.

Indeed. The lifting arm should give a straight lift. Why is it located
right at the end of the 'shaft'? It isn't, by any chance, that the rod
which pulls up the diaphragm was too long and, with the lifting arm
correctly positioned, doesn't lift the diaphragm high enough? If so,
shorten the rod (somehow).

However....
Once you've got the siphoning action started, it should keep going until
air gets in - which should be when water level in the cistern is almost
zero. If there are still 3 or 4 inches of water left, is air getting in
to the works and 'killing' the siphon prematurely? Maybe there's a split
in the cylinder or the inverted U-bend (especially at the top)?

Ours failed about a year ago at an inoportune time (visitors & shops

think I made it two layers. Still working now so not re-visited it!

Is there a bung missing from the side of the syphon? Sometimes (in theory)
removed to adjust the flush volume in replacement syphons.

Aha I found a hole low down on the side of the syphon. I pressed my finger
over the hole and flushed and a lot more water flushed away.
I will plug this with whatever I can find short term and asses if I get an
improvement, then get a proper plug for it.
I think there is only one bung hole, difficult to see properly.

Sounds and looks a bit like mine. Removing the bung puts it into dual flush
mode. For a full flush hold down the lever - this causes a piston to cover
the hole and it gives a full flush.

I`ll play around with that in the next few days in the meantime I emptied
the cistern, dried off the syphon and just used a piece of gaffa tape over
the hole, it should hold for a few days until I get a proper bung. Its now
giving a higher volume flush.

For full flush - press and hold.
For small (water saving) flush - press and release.

You have a dual flush toilet. Press & let go for a small flush. Press
and hold down for a full flush.

Nonsense. Most syphons you buy are dual flush. The size of the small
flush is adjusted by blocking/unblocking a series of holes with
plug(s) provided.


I did read it somewhere - this type was criticised as people often found
they had to flush twice to get the desired result because they didn't know
of the "Hold Down for Big Job Flush" feature. Water savings were negated by
people flushing twice. Modern types get round simpletons with two buttons.

Exactly why I never just change the diagphram. Very common to get a
near invisible split in the plastic moulding.

You can buy a new siphon for £5 from Toolstation & it takes the same
labour to change the diagphram as it does to change the siphon.

Thanks to all that responded, I have a good idea now what I looking for /
doing.
I have sorted the flush volume and the diaphgram I will leave until later as
it still works.
I have 2 other toilets in house so not an issue if it fails.

Thanks agian.
