40mm Valve / Waterless Waste Trap
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
