I took a quick look at a friend?s toilet cistern the other day as it seem ed to be misbehaving in the area where the water enters ? spilling water out and making horrible vibrating noises in the plumbing.
As I had no tools at the time I unscrewed the bottle cap-like top and took out the rather exotic washer and gave it a clean. It seemed better after th at but now I?m told it won?t fill. Apparently if they fill the cistern with a bucket they can then press down on the ball c*ck against the water a nd it?ll let water in ? which is of course pointless as the cistern?s full. Strange that it won?t let water in when the cistern?s empty. The water enters from the bottom of the cistern and the thing is all white plastic. House about ten years old. Shall I just replace the whole assembly or is it likely to be something simple (like a new washer) ? although I ?d have expected a new washer being needed to cause constant flow not no flow!
