I have a Twyford Toilet and Cistern, it keep doing a small flush every 45 mins, when I look into the pan it looks as if water is being poured into the existing supply.

Is there and adjustment to the existing setup or a replacement part I'll need to fit in order to stop the leakage into the pan and therefore the flushing problem?

is it going over your overflow is so your fill float valve is faulty, and letting by strip down and clean or fit new one.
