Toilet making a whistling or whining noise? Here's Who to Call
A high-pitched whistling, whining, or foghorn-like sound from the toilet tank usually means the fill valve is deteriorating. As the valve's internal seal wears, water forces through a smaller opening, vibrating the mechanism and producing noise. The sound often occurs right after a flush and can last 30 seconds to several minutes. While not an emergency, a worn fill valve wastes water and the noise will worsen over time. A plumber can replace the fill valve in under an hour, restoring quiet operation and saving water.
