It is important to ensure that the cold water main is capable of supplying the
UPPLY
increased demand which will be imposed on it. Hot and cold water are both
drawn off the same source of supply. Remember, there will not be a storage

A minimum pressure of approximately 1.5 bar and 20 litres per minute is
required for satisfactory operation. 85% of UK dwellings have a mains
pressure above 2.0 bar.

unit, for access.
