FINDING THE DEPTH OF YOUR WELL
IMPORTANT SELECT
CORRECT VOLTAGE
The jet tank system installs differently depending
on the depth of your well. Tie a small but heavy
weight to the end of a piece of string (be sure there is
enough string; some wells are very deep). Lower the
weight into the well until it reaches the bottom. Take up
the slack and mark the string at ground level. Pull the
weight out of the well and measure from the bottom of
the weight to the ground level mark. This is the depth
of your well. Subtract five feet from the depth of your
well. This number should not exceed the maximum
rated depth for your pump. If it does, it will greatly
hinder or prevent the proper operation of the pump.

Your pump is equipped with one of two types of dual
voltage motors. Follow the instructions to wire the
motor for the proper voltage. The voltage of the pump
must match the voltage of the power supply.

WIRING YOUR PUMP
Remove the cover from the pressure switch. Connect
the bare copper ground to the ground screw in the
pressure switch. Connect the power supply to the

DRAINING FOR SERVICING OR FOR WINTER
PIPING
The pump should be drained before it is disconnected
for servicing or if it is in danger of freezing. To drain:
• Remove drain plug from bottom of pump case.
• Remove discharge tee to vent the pump.
Plastic PVC pipe is shown in the illustrations, but
galvanized steel pipe may be used if desired. All piping
must be clean and free of all foreign matter to prevent
clogging. ALL JOINTS AND CONNECTIONS IN THE
WELL ASSEMBLY MUST BE AIRTIGHT. Even a pin-
hole leak will prevent the proper operation of the pump
(this is the most common problem). Use thread com-
pound on all threaded joints unless specified otherwise.
• Drain all piping to a point 3 feet below ground level.
SHALLOW WELL PUMP INSTALLATION (4" DIAMETER CASED WELL)
For wells 25 feet or less in depth, the ejector may be
attached to the front of the tank-mounted jet pump. For
lower depths, the ejector must be placed down inside
the well (see DEEP WELL PUMP INSTALLATION). All
materials with part numbers are quality Water Ace parts.
• One can PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• Two male 1-1/4" PVC adapters
• Enough rigid 1-1/4" PVC pipe and couplings to reach
from bottom of well to pump.
• One 4" well seal #RWS4-1012 with vent plug
• One 1-1/4" PVC elbow
General Materials
• One Jet Tank System #R-30-T7. Includes: 1/3 HP
jet pump mounted on a 7-gallon diaphragm pressure
tank, pressure gauge, and twin ejector with gasket,
bolts, venturi tubes, and foot valve.
Tools Needed for all pump installations
Pipe wrench, pipe clamp, crescent wrench, slot screw-
driver, 24-tooth hacksaw, knife or round file.
REMINDER: ALL JOINTS AND CONNECTIONS MUST BE AIRTIGHT. A SINGLE PIN-
HOLE LEAK WILL PREVENT THE PROPER OPERATION OF THE PUMP. USE THREAD
COMPOUND ON ALL THREADED CONNECTIONS UNLESS SPECIFIED OTHERWISE.

CAUTION: If you change pressure switch settings,

your pump cut-off pressure. Example: if a 20-40 PSI
pressure switch is being used, tank pressure should
be 18 PSI. If a valve shuts off and the cut-off setting
is too high, the pump will run continuously without

TROUBLESHOOTING CHECKLIST
(CAUTION: SHUT OFF POWER TO PUMP)
PROBLEM
POSSIBLE CAUSES
• Not enough water. Stop motor, remove pressure gauge plug, and fill case with water.
• Pump wired incorrectly.
• Plugged venturi tube or nozzle.
Pump will not prime
• Foot valve is sitting in sand or mud, or is stuck shut, or leaks.
• Low well water level. In deep wells, the ejector as well as the foot valve must be below
water level.
• Leaks. Check all connections for airtightness.
• Low well water level. Use a water-level tester while pump is operating.
• Plugged venturi tube, nozzle, or impeller parts.
Pump delivers water
for a period of time,
then stops pumping
• Plugged venturi or nozzle.
• Faulty pressure gauge resulting in false readings.
• In deep wells, the operating pressure may be too high.
• Low well water level. Use a water-level tester while pump is operating.
• Over-submergence of ejector. In deep wells, if ejector is more than 10 feet below
pumping level, pumping capacity is reduced.
Pump does not de-
liver rated capacity
• In deep wells, the ejector may have improper size and depth setting.
• Motor voltage does not match power supply voltage. See pages 2 and 3.
• Improper wire size. See Wire Size Guide on page 3.
• Impeller is rubbing against pump case.
Motor overheats and
shuts off (overload)
• Impeller neck is worn.
• Defective pressure switch.
• The tube connecting the two brass fittings may be clogged.
• Tank precharge pressure too high. Tank precharge pressure must be 1-2 pounds less
than switch turn-on setting.
Pump delivers water
but will not shut off
• In deep wells, the water level may be going below limit of ejector. Use water-level
tester while pump is operating.
Pressure switch
turns on and off
every few seconds
• Galvanized storage tank is waterlogged.
• Leaky foot valve.
• Too much tank pressure.
Motor fails or does
not operate properly
• If within Warranty, return pump/motor unit to place of purchase (with proof of purchase)
for exchange.
