Installation: FAQs
What are the temperatures requirements for cold water distribution?
To minimise the risk of contamination resulting from microbial growth and wastage due to taps left to run, cold water storage and distribution systems should be designed and installed to maintain a temperature not exceeding 20oC.
Plumbing systems should be designed and installed to ensure there is regular flow through.
To prevent undue warming, it is good practice to insulate both hot and cold water pipework. Unless it is adequately protected water fittings should not be installed where it could be exposed to heat sources, such as other services or sunlight.
For further information please refer to BS EN 806, BS 8558 and HSE Legionella ACOP.
