 toilet fill valve
Author: sum (FL)

After a toilet is flushed and when done refilling there is a high pitch noise that I can best described as similar to when you step on the brake suddenly on a rainy day.

I am trying to determine if this is water hammer or a fill valve issue. It does it consistently every time and a second bathroom toilet at the same property does not make this noise.

Replacing the diaphragm in the fill valve or replacing the fill valve entirely usually eliminates the squeal.

possibly just flushing the fill valve will do it,
