Abstract
Embodiments provide systems and methods for releasing grey water from an aircraft sink or sump using an improved waste water air stop valve. The valves described herein allow drainage of waste water, without air leakage. Additionally, if drainage in the piping is blocked, the valves are designed to ensure that water cannot flow back into the sinks or sumps.
