Flexible hoses provide a flexible solution to linking pre-installed or prefabricated pipework to building services components such as fan coils and chilled ceiling modules. Benefits include: time-saving and productivity during installation; allowance for minor misalignment of components; take-up of thermal expansion and contraction; isolation of noise and vibration. This code of practice has been written to help specifiers, installers, and maintenance operatives achieve the benefits that flexible hoses can provide while ensuring long-term reliability.
