  • Clause Reference : Schedule 2 paragraph 24 & G 24.2 (a)
  • Reference Number : B54
  • Decision Date : June 2012

When not in use it would be preferable for temporary filling loops to be completely disconnected and totally removed, however a partial disconnection, that is to say only detaching one end of the filling loop, will be permitted providing that the disconnection is made between the filing loop and the backflow prevention device on the supply pipe.
