I've just started to notice that water is slowly trickling into the toilet bowl. When I turn off the isolation to the toilet, the trickling stops and the water in the tank holds its level. I can't see any signs of anything overflowing, but my knowledge of plumbing is limited which is why I've attached a picture(!). The plumber has quoted £100 to sort, but given that when this siphon(?) system thing was fitted originally it took the plumber about 1 minute, I would like to think this is a job that I could do myself. Can anyone advise as to what the problem could be and how to sort it myself (again, bearing in mind my limited knowledge!).
