Installing the Priming Valve
2
1
Use the illustration and instructions to install the
priming valve. The illustration shows a typical
priming valve installation on a typical fire pump—
your specific application my differ in appearance.
Use the following guidelines when installing the
priming valve in your application:
•
The priming valve must be mounted above the
priming pump.
•
The vacuum hose or tubing must allow water to
drain from the priming valve to the priming pump.
•
If additional priming valves are installed on the
discharge side of fire pump, know that trapped
water can impede proper priming.
•
If required, use a hose or tube between the fire
pump intake and the priming valve instead of a
length of 3/8-inch NPT pipe.
1 Locate a suitable port on the pump intake.
2 Install an appropriate length of 3/8-inch NPT
pipe into the port on the inlet. Then install the
priming valve to the pipe.
