Push Button Flush Problem (Concealed Cistern)?

Hi All,

Would be grateful if someone could help me. I have a push button flush toilet with the cistern concealed in a cabinet. Recently when I push the Flush button, the button gets stuck and I have to unscrew the panel to push it out again. I had the plumber over today and he said 'the part which pushes the air through the air tube is knackered' and it will be about month before he can get another replacement part in'. I asked him how am I supposed to flush the toilet in the interim, he told me to blow into the air tube (I am serious).

Is there anywhere, where I can buy the replacement part myself ( I don't have a name, but I can take a photo and e-mail it to anyone who can help me name it). Also, if I cant get a replacement part in the near future, is there a temporary fix......is there anything else I can do to stimulate air going through the air pipe to ensure the toilet flushes ?

Please Help
