I live in Australia, and we have an Imperial Brand toilet that is around 3 years old with a dual flush system. The half flush has suddenly stopped working – it only keeps the valve open while you have the button pushed, whereas it used to hold the valve for a short period, then close it so the toilet could refill.
(Note – I am not a plumber as you can probably tell, so apologies if I sound dumb)
I have taken the top of the cistern off, and there is a cantilever type mechanism that causes the push to pull the valve at the bottom of the toilet up. I can’t work out how this is supposed to be held up.
The full flush works fine.
would appreciate any advice as to how I might fix this. Thanks in advance!
