DISCHARGE PLUMBING
Fig. 1 illustrates a typical well installation showing
above ground components. Adhere to the following
items when installing the discharge plumbing.
1. Install an above ground check valve upstream from
the pressure switch.
2. Always install a pressure relief valve in the system.
The relief valve should be capable of discharging the
flow rate of the pump at the rated working pressure
of the pressure tank. Locate the relief valve close to
the pressure tank.
3. Install a pressure switch between the check valve
and the pressure tank. Refer to Fig. 2, 3, or 4 for
proper wiring connections of pressure switch.
4. Install a pressure tank as close as possible to
the pressure switch. Refer to manufacturer's
recommendations for installation.
TROUBLESHOOTING
1. PUMP FAILS TO START
a) Electrical trouble - call dealer or electrician.
b) Drawdown protection device has pump turned off.
c) Overload tripped.
d) Reset low pressure cutoff switch (if installed).
2. PUMP FAILS TO DELIVER WATER
a) Air lock in pump.
b) Clogged intake screen.
c) Insufficient well yield.
3. PUMP GIVES REDUCED OUTPUT
a) Insufficient well yield.
b) Worn pump.
c) Clogged intake screen.
d) Low voltage.
e) Incorrect rotation (3-phase only).
4. PUMP CYCLES TOO FREQUENTLY
a) Excessive pressure drop between pressure switch
and pressure tank.
b) "Cut-in" pressure at pressure tank too high.
c) "Cut-out" pressure at pressure tank too low.
d) Waterlogged pressure tank.
e) Start and stop electrodes of floatless liquid level
control set too close together.
f) Tank sized too small to meet system requirements.
5. OVERLOADS TRIP
a) Electrical trouble - call dealer or electrician.
6. PRESSURE SWITCH CYCLES RAPIDLY WHEN
PUMP STARTS
a) Pressure switch too far from pressure tank.
b) Adjust air charge of tank to manufacturer's
recommendations.
