What Causes a Toilet to Whistle

Strange sounds coming from a toilet are never fun for homeowners. More often than not, it means that there is a problem brewing. A common sound that signifies a repair is needed is a whistle. Sometimes it can be a soft whistle or an ear-piercing scream. Either way, you’ll need to call a plumber in Manhattan to investigate the sound and pinpoint the cause.

What causes a toilet to whistle? Most of the time, a whistling from your toilet indicates an issue with the toilet fill valve. There is a float located in the fill valve, which rises and falls with water levels. This process regulates how much water enters the tank after you flush. As the float drops lower, the valve opens to allow the tank to refill. The valve shuts when the ideal water level is reached.

When your fill valve is working properly, there shouldn’t be any noise. However, fill valves do age with time and begin to deteriorate. As the whistling gets louder, the bigger the problem becomes. A loud, shrieking sound indicates that the valve is almost at a complete failure, which can mean disaster for your bathroom as it may lead to flooding.

We normally fix a broken fill valve by replacing the gasket or the whole valve. Thankfully, this is a relatively easy fix. However, it’s best to leave the work to the professionals to ensure it’s done properly and safely.
