PRIMING THE PUMP

NOTICE: 'Priming' refers to the pump expelling all air in the system and
beginning to move water from its source out into the system. It does not
refer only to pouring water into the pump (although pouring water in is
usually the first step).
NOTICE: NEVER run pump dry. Running pump with out water in it will
damage seals and can melt impeller and diffuser. To prevent damage, fill
pump with water before starting.

1. Remove priming plug (Figure 14).
2. Make sure suction and discharge valves and any hoses on discharge side
of pump are open.
3. Fill pump and suction pipe with water.
4. Replace priming plug, using PTFE pipe thread sealant tape on thread;
tighten plug.
NOTICE: If a priming tee and plug have been provided for a long
horizontal run, be sure to fill suction pipe through this tee and replace
plug. (Don't forget to tape the plug.)
5. Start pump: water should be produced in 10 minutes or less, the
time depending on depth to water (not more than 20') and length of
horizontal run (10' of horizontal suction pipe = 1' of vertical lift due to
friction losses in the pipe).

If no water is produced within 10 minutes, stop pump, release all
pressure, remove priming plug, refill and try again.
pump is run con ti nu ously at no flow (that is, with discharge shut off or
without priming), water may boil in pump and piping system. Under
steam pressure, pipes may rupture, blow off of fittings or blow out of
pump ports and scald anyone near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is open whenever
pump is running.
B. If pump fails to produce water when attempting to prime, release
all pressure, drain pump and refill with cold water after every two
attempts.
C. When priming, monitor pump and piping tempera ture. If pump or
piping begin to feel warm to the touch, shut off pump and allow system
to cool off. Release all pressure in system and refill pump and piping
with cold water.
