How to increase the volume of water used in the flush?

some cisterns have a dual flush mechanism try flushing quickly wait a bit then try a long flush if theres no discernable difference try checking that the ball valve is set to the correct height.(there should be a water fill line inside the cistern use this as a guide)

It's a fair bet that the plugs that push in the side of the syphon to convert to either 6/7 or 9 ltr flush have fallen out, so the water will on flush away until air gets in to stop the syphoning effect. If you call steve at toiletspares.co.uk he'll talk you through it, he's an absolute wiz on toilets !!!!
