MacValve Self-Closing Waste Valve


  • Can be fitted in horizontal or vertical position
  • MacValve 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
  • MacValve can be fitted in installations where a non-return valve can be of benefit to the plumbing installation
  • MacValve can be used to take the discharge from a pressure relief valve on an unvented domestic hot water storage system. Please refer to guidance notes in approved Document G3 of the Building Regulations
  • MacValve having no water seal can never dry out through evaporation or lack of use of an appliance as the membrane remains sealed
  • MacValve is not recommended for use with shower trays unless there is access for maintenance
