I wonder if anyone can help please ? One of our toilet cisterns has developed a "clunking" noise when the re-filling process finishes. It does it on both the long and short flush. It's about 9 years old. I know my way around ball valves but this is all new to me. Can anyone tell me why it is making this noise please and if it's possible to get rid of it ? The chrome thing is what screws through the top and into the mechanism when it's in position but thought I would show it. If I had to guess I would have to say that the noise is coming from the bit on the left. Is that the shut-off valve ?
Thanks in advance for any help given.
