suction pipe will be required, the diameter of which should match the pump suction as an
absolute minimum.
In situations where the town mains supply cannot be utilised directly it will be necessary to
install a water storage tank (break tank) between the incoming mains water supply and the
FireSAFE
unit, it must however have a type AB Air Gap and be supplied and installed in
accordance with the Water Byelaws Regulations. Grundfos can offer a suitable break tank.
