Akatherm Drainage System

  • HDPE drainage provides high temperature chemical resistance for use in commercial buildings
  • Full range of pipes and fittings available
  • Flexible but strong jointing system
  • Includes the Akavent single stack drainage system (that eliminates the relief venting requirements of traditional drainage systems)
    • The system is specifically designed for multi-storey building applications
    • It slows the downward flow of water to prevent the formation of hydraulic plugs
    • Prevents waste water from branch lines mixing with other waste water until below the junction point
    • Has only one outlet pipe, replacing the need for a conventional two-pipe fully-vented or a fully ventilated modified stack system
    • Provides significant cost savings through reduced pipe work and associated construction increasing flexibility for architects and designers of multi-storey buildings
