PUMP RUNS CONTINU-

OUSLY

A. Pump water supply restricted.

B. Pump discharge line restricted.

C. Inefficient or worn pump.

D. Overdrawing.

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.

NOISY PUMP A. Bad motor bearings or worn pump

shaft.

B. Failure of Triac on liquid level

control.

C. Insufficient water supply.

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.
