The smart alternative to traditional traps and most innovative advance in plumbing since the water-seal trap.

Unlike most waterless traps that rely on a waster seal, this 40mm trap uses an elastomeric membrane that is enclosed within that allows water to pass through, then closes once the flow is complete, forming a tight seal.

Great space saver and can be installed both vertically and horizontally (with the use of a knuckle bend).


BSP female inlet nut x universal compression outlet
Membrane opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent foul odour or sewer gas entering the building
Can be fitted in horizontal or vertical position
Can be fitted in installation where a non-return valve can be of benefit to the plumbing installation
No water seal so it can never dry out through evaporation or lack of use of an appliance as the membrane remains sealed
