Remedy
A. Check water filter and pump inlet
strainer and clean. NOTE: Noisy
pump operation usually indicates
restricted water supply. Also
check for faulty double check
valve, water leak or low pump
bypass.
B. Water inlet check valve may be
plugged. Remove, clean, or
replace rubber O-Rings.
C. To test for efficiency, disconnect
discharge line from pump. Con-
nect a 300 pound gauge and
hand shut off valve to pump dis-
charge. Start pump. Bleed off any
air, close hand valve then observe
pressure. If it is approximately
180 PSI, pump is O.K. If it is sig-
nificantly below 180 PSI, it may
be increased by adjusting the
pump by-pass. Increasing the by-
pass is accomplished by remov-
ing sealing acorn cap and turning
the adjusting screw in. If pressure
rises to 180 PSI, pump is O.K. If it
is still below 150 PSI, and the
screw is turned all the way in, the
pump is worn. Replace. NOTE:
Abadly worn pump and/or prema-
ture failure usually indicates for-
eign material in the supply water.
Install a water filter in supply line.
Also check for faulty liquid level
control, corroded electrode, or
broken pump shaft.
D. Check capacity of pump. The
combined rate of flow from dis-
pensing valves should not exceed
the stated GPH for pump, or
pump will run continuously.
A. Repair or replace motor.
B. Repair or replace liquid level con-
trol.
C. Check that water supply is on.
Also check for clogged water fil-
ter, ruptured tank or bad double
check valve.
