Hello!! I am desperately seeking help!! I have an Ideal Standard Dual Flush toilet that has recently started to overflow - that is the water is tipping over into the overflow pipe! I cannot see how I can adjust the water level to stop this? I have attached some pictures hoping that someone can help me??

Your replies will be greatly received!!

Probably a bit late replying now, but it could be at the bottom of the syphon is a rubber seal - this sometimes get a bit of muck on it - give it a wipe round.

Sorry ignore what I just said- the overflow pipe can be adjusted up or down by twisting it. But the problem is probably due to the washer in the inlet valve.
