After my Fluidmaster equipped toilet finishes filling, I get the water
hammer sound. From research, it appears to be caused by the F's fill
valve. Can this be corrected or do I have to replace the entire
assembly? Can the fill valve be replaced? Any other relatively easy
solutions?

Thanks for any info.

Close the cut off valve that feeds the toilet. Leave it open just
enough to fill slowly.
