5.4.2 Flexible Hoses
The flexible hoses are accessible behind the pump assembly. To gain access, the pump needs to
be removed. There is an access hole in the bulkhead that allows the engineer room to remove the
hose clips (see Diverter Valve graphic below). The hoses (items 3 and 5) and the riser pipe (6) are
attached using 45-60mm worm drive hose clips (2).
