Ours is crap (pun intended).

It's slowly getting worse at flushing over time and since yesterday now it takes quite a few attempts to flush.

Having a look in the cistern, it looks like there's not enough "pressure" when flushing it for the water to shoot up and drop down into the toilet bowl, see photo below:

Has the flushing mechanism part just worn out and needs replacing? I can see when trying to flush it the liquid goes up into the oval shaped bit but drops down when it fails to flush, hence wondering about the "pressure" part.

Excuse my terminology, plumber I am now :/
 
If anything like mine it was due to the skirting inside the thingeymajiggy having a rip in it. That meant it took several yanks on the chain before a seal was formed and it flushed correctly. Had to replace the entire thingeymajiggy.
 
Ours did this, it was the diaphragm in the bottom of the mechanism that had failed which is apparently a common area so it wasn't lifting the water up to start the syphon process into the bowl.
I replaced it with a eco-flush job from screwfix which was fairly simple to do!
 
Looking at the picture I don't think this is your problem but just check.
I had to unblock a toilet once and after faffing about outside and not finding any pipes blocked I started on the toilet itself and all it was was that white arm that goes up and down when you press the lever -The arm had slipped along the shaft till it got to when you pressed the handle it stopped when it hit that white dome thing so it didn't have a full flush - the other thing was it was a syphonic system -it needed full flush to work.
The thing I found amazing is how people use a full to brim bog. - I would get a bucket out and tip it down a manhole.
 
I’d replace the entire flush system and the filling device. £30 odd and about 30 minutes if you take your time. Easier if you have a valve to isolate the feed to the filling device inside of the bathroom.

Unless you’re trying to save water, the water level is on the low side which will give you a less powerful flush.

Also, I’ve read that some of those bog water colour things can erode the neoprene seals.
 
Thanks guys for the input and for the screwfix link, suspected it would need a new flush system.
And yeh I can isolate the water supply as there’s a valve just under the cistern on the inlet pipe :)
 
Well it’s going really well, I ignored the link above and bought a different one that apparently is the best and it doesn’t fit one way as the inflow pipe fouls against it.
And then I didn’t have the correct tools to remove the old one so had to bodge it and saw bits off.
And now the service valve is leaking so need to replace that.

What should’ve been a 30 min job has taken a few hours and still isn’t finished.

Taking to old part doesn't always ensure that you got the correct part...! :eek:

The previous windscreen had also been fitted using incorrect bolts, which were replaced by the shift maintenance manager on a like-for-like basis without reference to maintenance documentation,

I actually felt sorry for the service engineer on this one. He probabally thought he was going the extra mile to get it right! :(
 
On some of these you can just unclip/unscrew the mechanism to replace the (probably torn) diaphragm. A couple of quid from your local plumbing supplier, and easier to fit than replacing the whole mechanism.

Always assume that plumbing jobs will never be as quick, easy, or simple as you expect.

I think I'm 99% finished, just some small drips from underneath when flushing.
Ended up buying the siphon part that @akaFonzie recommended, put in a new filling device too.
