« Last post by Russell on Today at 06:46:24 pm »From the WRAS website for approvals for this manufacturer for a similar tap:
Installation Requirements:
IRN R010
Water supplies shall be at reasonably balanced pressures from a common source (e.g. hot and cold supplies both from the same storage or both from a supply pipe). Where the fitting is supplied from unbalanced supplies (e.g. hot and cold supplies from separate sources) an ‘Approved’ single check valve or some other no less effective backflow prevention device shall be fitted immediately upstream of both hot and cold water inlets
