Self Closing Waste Valve - Loose Nut x Compression

Ideal for plumbing applications, the McAlpine 1½” Self Closing Waste Valve is the perfect combination of convenience and reliability. The valve boasts a self-closing mechanism for worry-free plumbing, along with a loose nut and compression for easy installation. Get the perfect waste valve for your next project.

  • 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
  • Not recommended for use with shower trays unless there is access for maintenance
  • Patent Pending
