What does a toilet flushing sound like?

The sound a toilet makes when flushed is usually that of rushing water. Pulling the flush handle causes a flap in the tank to open and release the water held in it.

Although some toilets have a quieter design, the most common use the typical flush valve. The water rushing from the tank when the valve opens is what causes the sound heard when flushing. This noise should not be confused with gurgling or the sound of running water, which could indicate problems with the toilet. If a toilet makes unusual sounds, homeowners can contact a qualified plumber for diagnosis and repair.
