Why does my toilet whine/whistle each time it is flushed.

Welcome to Just Answer.

This is an easy fix and will cost nothing, but a little of your time.

The noise you hear is caused by the vibration in the stem and washer assembly.

Shut the water off under the tank and remove the three screws securing the top of the ballcock assembly, that is inside the tank. Pull the float ball, stem and washer assembly up and out. Pry the washer out and turn it over pressing it in in firmly. Place your hand over the open ballcock and reach down and turn the water back on to flush out any crud that might be in there.

Reassemble and give it a test flush. The sound should be gone.

Best of Luck, Brian

Thank you.


Thank you for asking your question on Just Answer. Brian may have supplied you the answer needed, if so please accept his answer. He may also be correct on why the noise is the problem. I would like to provide this additional information. There are several type of toilets and also different type of fill valves. Many toilets have the type fill valve that Brian described the repair for. Others do not. If your toilet has a fill valve it is often easer to replace them than to repair them. The video below shows how that is done.
