Dripping Sound from Inside of Wall/Ceiling When Toilet is Flushed

[Mdmm55]

I don't think your existing tube looks smaller.

When on the valve, that tube will look similar to this:

However installing a new float valve would certainly be good. It is a little more work that swapping out the tube.

Thank you very much Reach4.
Again some dripping sounds are coming but less in frequency. What is your opinion??
Water level is high in filling tank. Should I reduce the water lever a little bit to see if it effect??
How to reduce the water level in water tank (in picture), please.

If there is an adjustment on the end of the arm shown in https://www.terrylove.com/forums/index.php?attachments/val-1-jpg.80620/ then you might want to use that. Otherwise you lower the top of the assembly so the float sits lower. If you identify the fill valve, you will be able to find a web page and a YouTube video to tell you how to adjust.

Water should not come to more than within 1/2 inch of the overflow. I think 3/4 is usually recommended. If the water level is high, water can wick up the clip and down the overflow.

if you are hearing a loud rattling it needs addressing but a slight dripping sound or ticking sounds is not unusual however can be scary many times usually it can be ignored But I cant tell you that too many variables . I might disconnect water supply from toilet open valve allow to run in bucket and see if it came from drainage or water supply, but likely wouldn't do anything depending on the noise

Thank you very much. I acted upon your advice.
1- Lowered the water supply to filling tank,
2- Adjusted the level of water in the tank about half inch, lower.
Now there is absolutely no dripping sounds.
Your advices were helpful, which saved me in hiring a plumber.
