The Anatomy of Toilet Bowl Guts

Toilet bowl guts consist of the trapway, flapper valve, siphon, and bowl rim. The trapway channels waste into the siphon, where a seal prevents sewer gases from entering. The flapper regulates water flow, while the siphon triggers a flush that clears debris. Together, these elements form a sealed, efficient system designed for durability and performance.
