Had the outside water pressure regulator replaced and set to 55psi. Now the toilet has a high pitched sound from the valve that shuts off the water by the float. If I shut-off the water while the toilet refills the sounds goes away when I open it to refill or if I move the ball float around the sounds stops while filling. Our other toilet has no problems. Thanks

Which type of fill valve do you have?

The one on the left, with the colors

Turn off water to toilet, remove screws holding cap around 5. Remove cap and seal. Hold cup upside down over valve, turn on water briefly to flush out valve. Reinstall cap and seal. If problem continues repeat and replace seal.
