From experience it sounds like the water inlet valve is faulty. This problem is common with equilibrium float valves. You can change the washers or as the fitting is so cheap, replace the whole valve.

If you are paying to have this work done, value for money would say get the valve replaced. Saves messing about later on

sounds like to me that the inlet valve e.g ball valve is jumpling causing water hammer along the pipes.

If it sounds like a'ships horn' then isolate water strip and clean filling valve assembly
replace seals and re-try or as the other answers.
