Downloads
  • Available in 1¼" and 1½" sizes
  • 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
