Section XVIII. PUMP DISCHARGE MANIFOLD
The purpose of the pump discharge mani-
fold (8) is to provide a multiple connection for
discharge hoses. Two 4-inch gate valves (12)
are mounted on the manifold. Each gate valve
is equipped with a flange adapter (11) and
dust cap (13).

Maintenance and Repair
a. Removal and disassembly.
(1) Remove the dust caps (13).
(2) Remove the nuts (5) and lockwashers
(4) and cap screws (7) securing the
adapters to the gate valves (12), Re-
move the adapters and gaskets (3 and
