Water Supply Industry Interpretations and Advice

  • Area of Interest : Backflow prevention
  • Topic : Fluid category
  • Title : Washbasins in hairdressing salons.
  • Clause Reference : Schedule 2 paragraph 15 & G15.3
  • Reference Number : B10
  • Decision Date : October 2001(Revised October 2015)

Unless a risk assessment of the hairdressing premises, and hair washing solutions, colourants and bleaching agents to be used determines otherwise, it is considered acceptable that flexible hoses used as part of the shower attachments employed in these treatments be protected by a fluid category 3 backflow prevention device, such as a double check valve.

Please note the use of some chemicals could warrant the installation of higher levels of backflow protection.
