"Singing" Toilet

Hello all,

The master bath toilet "sings" when the tank is close to shutting off after re-filling. This happens about 9 out of 10 times. I thought it might be the home's water pressure, but this is the only one of 3 toilets in the house that does this.

Any thoughts and/or solutions?

It could still be higher than normal pressure and just not affect the others.
Make sure the shut-off valve is fully open too.

Singing requires a pretty specific set of circumstances. Something like a burr inside the fill valve, water pressure, flow volume can be the one piece of the puzzle to set up a resonance. If you disturb something it likely will stop the singing. Fill valves are cheap so if it continues you can try replacing it with a new one.

I'll go along with PD. Change the fill valve and see if that fixes it.

PJ said to make sure the supply valve is fully open. If it is, try closing it just a bit. Sometime just a small change is enough to make a difference.

Thanks for the suggestions & comments. The shut-off to the toilet is fully open, so I'll try closing it a bit for starters. Fill valve will be "plan B".
