Installation: FAQs
Do 'dead legs' have to be removed?
Yes, dead legs should be removed as they are a potential source of contamination. If the dead leg cannot be completely removed any blind end should be as short as possible.
All plumbing systems should be designed to ensure a steady through flow of water. For pipework supplying fittings which are used infrequently i.e. fire supplies or water reuse systems with a back-up supply, appropriate backflow protection should be installed as close as reasonably practicable to the mains or supply/distributing pipe.
