What type of valve uses a jumper in plumbing?

A jumper valve, commonly referred to as a jumper valve or a toilet flush valve, is often used in Plumbing systems to control the flow of water in toilets. It features a flexible rubber or plastic component that acts as a seal, allowing water to flow when the toilet is flushed and preventing backflow when not in use. This type of valve is crucial for maintaining proper water levels in the toilet tank and ensuring efficient flushing.
