Pneumatic cistern wont flush

[Redhotferrari]

Hi Guys,

As in title, have a problem with a built in cistern, that the push button has a tube to flush the cistern, have checked inside and the concertina type push thing is over the flush, and it will flush by manually pushing down the flush., so I assume the problem must be with the tube or the button?

are these servicable, or do I require a replacement? There is no make or model anywhere, but the flush looks like a grohe one.

Any advice would be appreciated

hi sounds like u have a problem with the inner plastic tubes check to see if there are creased or misshaped in any way, as that can prevent them from flushing properly. if so just snip them back and coonect them again then the button shouldnt stick.

does this help?

The button is not stuck and freely moves in and out, just does not seem to be doing anything, its does not appear to be loose either!

It seems that its simply not creating a build up of air to push the flush down, have pumped the button whilst feeling around the tube and cannot feel any air escaping.

Starting to drive me mad!!!

The push-on tube is probably kinked. You can cut the kinked bit off and start again but it will get kinked again. You need a push-on elbow, but I don't know if such exists. A real pain.

You need a new push button, look here about 17 down
