AI Technical Summary
Technical Problem
Existing toilet systems with in-line pressure flush engines struggle to operate reliably under insufficient in-line water pressure, leading to poor flushing performance.
Method used
The integration of a gate valve with a flapper and biasing member that allows for pre-priming of the toilet bowl and trapway with water, enabling reliable flushing even under low in-line pressure.
Benefits of technology
The gate valve system ensures effective flushing and waste removal by pre-priming the siphon, allowing the toilet to function consistently regardless of changes in in-line pressure.

Abstract
A gate valve for a toilet includes a channel configured to conduct a flow of fluid, a flapper disposed in the channel and movable between an open position and a closed position in which the flapper blocks the channel, and a biasing member configured to bias the flapper toward a closed position.
