Yesterday I noticed that a toilet was making much more noise than usual when it was filling, so I removed the lid. It has a Torbeck valve and the water, instead of filling the cistern via the long plastic tube, was coming straght out of the four small holes on one end of the top - see red arrow in this pic.
Does anyone know why it is happening and what the cure is?
