I Would be grateful if someone could help me. I have a push button flush toilet with the cistern concealed in a cabinet. The air button is no longer flushing the toilet and I had opened the cabinet, released the plastic tube from the push button and flushed the toilet by blowing air through it. I seems that the air released by the button into the plastic tube is not sufficient. At the end of the tube there is a small plastic cylinder that increases in height with the pumped air. I cannot detect air leaking from it.

Please help.

Thank you.

None of mine work . Thought it was the way they were installed but now that I see all of your above comments , I think I will have to replace them !!

Inside the button is a rubber bellows. When you press the button it compresses and sends a burst of air down the tube. Unfortunately the rubber splits and then there is insufficient pressure to inflate the concertina plastic. We've replaced the button once and its failed again exactly the same way eight months later. Poor design and manufacture. I'm looking for a compatible button/system that isn't pneumatic.

Hi Vera, did you fix this? We are also having the same problem - the plunger at the flush mechanism end is not raising sufficiently to allow the full flush to take place. The volume of air and pressure does not seem sufficient to raise it (having blown down the pipe to establish all is well at the "slave cylinder" end....

I would like to thank Heather for her advice. As suggested, I have checked that the ‘two lips of the diaphragm fall on either side of the edge of the pipe that drops and initiates the flush. I think the problem is that the ‘concertina cylinder’, fitted at the end of the plastic tube, does not increase in height sufficiently to push down the pipe as far down as it is necessary. In other words, the amount of air injected through the plastic tube by pressing the push button is insufficient. How can I correct this?

Hi Vera
No that didn't work.
We were supplied with a spare handle. This has now been fitted and seems to be working.

There is two little lips on the concertina, going to the diaphram - have one lip either side of the open end of pipe that drops down to make it flush. Hopefully this will remedy the cause.
My husband has just mended (I hope) ours, after having weeks of pushing the button many times before it flushed.
Hope you understand, I am not a plumber.
