OPERATION
Priming the Pump
NOTICE: To properly prime the pump, install a pipe tee in
the discharge piping (see Figure 1, Page 4).
To prevent damage to internal-parts, do not start motor until
pump has been filled with water. .
To prime pump:
1. Remove priming plug (Purchase separately; Figure 1,
Page 4).
2. Fill pump with water,
3. Replace priming plug, using Teflon tape or Plasto-Joint
Stik^ on plug threads; tighten plug.
4. Start the pump. Water should be pumped in 1-2 minutes.
If not, repeat steps 1, 2 and 3-
On shallow depths to water (10 feet or less), the pump
will probably prime the first time after the following
steps 1 through 4 above.
From 10 to 20 foot depths, you might have to shut off
the pump and repeat steps 1, 2 and 3 several times.
5. If, after priming pump several times, no water is
pumped, check the following:
A. Be sure suction pipe is in the water.
B. Be sure suction pipe does not leak.
C. Be sure that pump is not trying to lift water too high
(see “Piping in the Well", Page 4).
D. As long as foot valve and check valve function cor­
rectly and suction pipe does not develop leaks, pump
should not need repriming in normal service.
