Trade Quality Floor Trap 4-Inch One-Way PVC

Floor Trap 4-Inch

The Trade Quality Floor Trap 4-Inch model provides a reliable solution for managing wastewater in residential and commercial wet rooms. This 110mm fitting integrates a one-way mechanism to ensure that drainage flows away from the structure while blocking foul odors and pests from entering the building through the pipes. It serves as a primary barrier between the living space and the subterranean waste system.

Built for the Job

Plumbers and site supervisors specify this component for high-traffic wet areas where hygiene and air quality are non-negotiable. It handles the volume of standard 110mm drainage lines efficiently. The one-way design is critical for maintaining air quality in indoor spaces by preventing sewer gas bypass. Professionals install these in concrete screeds during the first-fix plumbing stage of construction or renovation.

• Installation in bathroom floors to manage shower and floor runoff.

• Use in commercial kitchens to prevent grease trap odors from rising.

• Application in laundry rooms to handle high-volume machine discharge.
