A homeowner experiences water hammer noise when a toilet fill valve closes, and seeks a quieter, slow-closing replacement before installing a dedicated hammer arrester.

Existing fill valves like the Fluidmaster 400H-002 close too abruptly, causing water hammer noise; no specific quiet-close valve is known to the user.
