A toilet that whistles, hisses, or knocks after the flush is telling you about the fill valve or the supply. The sound is usually the valve doing its job poorly, and the fix is often a simple adjustment.
The hiss
A hiss after the flush is water leaking past the fill valve, and it keeps running until the tank is full. A worn or scaled valve is the usual cause. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Burlington, hard water scales the valve faster.
The whistle
A high-pitched whistle as the tank fills is the water squeezing through a restricted valve, and cleaning or replacing the valve quiets it.
The knock
A knock when the fill valve closes is a mini water hammer, and an arrestor or a slower-closing valve fixes it.
The check
Watch the tank after the flush — if the water keeps running or the sounds continue, the valve or the flapper needs attention.
