We have a toilet with the cistern built into a cabinet, with a button on the front to flush it. However, it only seems to flush if you press the button right in (quite deep) and you have to do it quite swiftly at that.

I took the panel off and unscrewed the button to have a look at it, but there doesn't appear to be any movable part that would adjust this. The button (it has two button for a dual flush type thing) is connected to the cistern by two long bits of flexible plastic tube. I can't tell if they contain water or air from looking at them?

Someone suggested that shortening these pipes would fix it - but I obviously don't want to cut them and then have a problem.

Any ideas what actually causes this? Should I just cut them shorter and reattach them? If so do I need anything special to attach them (glue?) or should they just slide on/off.

Once the flush starts the flush works perfectly fine - this isn't a problem like other questions about having to hold the button down etc. It literally just seems to be that the "trigger point" for the button is very deep. I'd like to raise that to make it more sensitive so that you don't have to press it so far.

The reasoning for cutting them shorter is that it is a pneumatic link between the button and the cistern. So when the button is pressed, this compresses the air in the tube, and applies pressure at the other end causing the flush. If so, reducing the length of the pipe would reduce the volume and hence mean less compression needed to produce a response at the other end (and hence shallow press of the button). I have no idea if this reasoning is gibberish or not.

it might be that your button or trigger is worn making it less sensitive – ratchet freak Sep 25 '13 at 13:35
