PRIMING THE PUMP
NEVER run pump dry. Running pump without water may
cause pump to overheat, damaging seal and possibly causing burns to per-
sons handling pump.
Fill pump with water before starting.
NEVER run pump against closed discharge, to do so can boil
water inside pump, causing hazardous pressure in unit and possibly scald-
ing persons handling pump.
NOTE:
Open water system faucets before priming pump for the first time.
Step 1. Remove pressure gauge.
a. Close regulator valve (turn clockwise - see Figure 13).
b. Fill pump and suction pipe with water (Figure 13).
c. Replace pressure gauge, using Teflon tape on thread; tighten
gauge.
IMPORTANT: If a priming tee and plug have been provided for a long hori-
zontal run, be sure to fill suction pipe through this tee and replace plug.
(Don’t forget to teflon tape the plug.)
Step 2. Start Pump:
Pressure should build rapidly to 50 pounds per square inch or more
as ejector and pump prime.
IF NO PRESSURE OR NO WATER, REPEAT Step No. 1 (above) two or three
times to remove entrapped air from the suction pipes.
Step 3. If, after priming pump several times, no water is pumped, check the
following:
a. Suction pipe in the water and has no leaks.
NOTE:
Air can leak in even where water won’t leak out. Make
sure all joints are tight.
b. Control valve, check valve, or foot valve installed and operating
correctly.
c. Pump trying to lift water more than 25 feet (shallow well) or
more than rated lift for deep well ejector used (including com-
pensation for horizontal offset).
d. Be sure pump is not airlocked. In offset installations, pump suc-
tion port should be highest point in suction pipe; there should be
no sags in suction pipe (run it straight and at a slight angle
upward from well head to pump).
NOTE:
For deep well installation, go to Step 4 (Page 11). Shallow well
installations go to Step 6 (Page 11).
