Description

A one-way flap (check valve) that directs airflow/liquid in a single direction to prevent backflow and protect the appliance's internal components. Replaces a worn or damaged flap to restore proper flow control. What it does

• Blocks reverse flow to prevent odor, water, or air from returning into the appliance.
• Helps maintain correct drainage/venting or airflow depending on application.
• Commonly needed when you see intermittent backflow, odors, or reduced drainage/venting performance.
• Works as a passive one-way seal—no electrical connection.
