Hose to pump:
The pump inlet and outlet ports have moulded fittings which
are specifically designed for connection to the G ¾ female running nuts on the
flexible hoses. The hose end running nut is fitted with a rubber sealing washer
which is held captive within the nut assembly. Locate the hose into position and
screw the nut fully onto the fitting by hand. Finally nip tight with pliers (4/5 Nm)
for a water tight seal
(do not overtighten)
