Pressure Feed (or Gravity Feed) Method: (Preferred Methods)
1. Fill the water line (or test vessel) to be tested prior to pump connection.
2. Connect water supply hose to the garden hose inlet connection (G) on the pump.
3. Open valve and turn supply water on.
4. Purge the pump and pressure hose of all air.
5. Connect output (pressure) hose between pump output connection (I) and water line
(or vessel) being tested.
6. Turn pump on.
7. Purge water line (or vessel) of all air at the highest point of the system.
8. Bring water line (or vessel) to pressure. Watch the gauge (A)
while pumping. When the desired pressure is achieved, turn
the isolation valve (B) to the “off” position. The engine can now
be turned off. If pressure drops, there is a leak in the line.
Siphon Method
Use a clean water source
1. Fill the water line to be tested.
2. Fill the intake hose (WR PN #34550) with water, then quickly place the hose into a
bucket and turn pump on. (The unit is self-priming once primed.) Continue to pump
until you see the water coming out of the outlet, with little or no air mixed with it.
3. Connect the output hose to the water line. Continue on with steps 6 through 8 in
pressure feed method.
Pre-Setting Your Pump
Your pump can be pre-set to a specific pressure easily by adjusting the pressure relief valve.
1. Unscrew (counterclockwise direction) pressure relief valve knob (C) a few turns.
Be sure not to unscrew valve knob all the way as internal parts can be easily lost.
2. Add a ball valve (not supplied with pump) to the end of the high pressure hose.
3. Follow steps 2 through 4 from the ‘Pressure Feed Method’.
4. As water is flowing out of the high pressure hose, turn the ball valve to the “off”
position.
5. Slowly start turning pressure relief valve knob (C) (in the clockwise direction) by
¼ turn increments, until you reach the desired pressure. Maximum pressure is
1000psi or 2000psi - depending on the model. Tighten jam nut (B) to lock pressure
relief knob in place.
6. Your test pump is now pre-set. This eliminates over-pressurizing the water line (or
the vessel).

Troubleshooting Your Pump
Test pressure not being reached:
 Possible air in line (or vessel)
 Air needs to be purged from system.
 Remove pump from system and follow steps 1 thru 6 of the
“Pre-Setting Your Pump” section.
 If using the Siphon Method and not getting pressure, try the
‘Pressure Feed’ or ‘Gravity Feed Method’ to ensure water is
getting into the pump.
 Check strainer (H) O-Ring for cracks.
 Check inlet quick disconnect (G) O-Ring for cracks
 Pressure relief valve not adjusted properly.
 Turn relief valve counterclockwise and watch for change in
pressure.
Pump Maintenance
 Pump 50/50 antifreeze/water solution through pump after each use to
lubricate internal parts of pump and to avoid freezing in cold weather.
 Check strainer O-Ring (H) for cracks prior to each use.
 Check oil level through oil sight glass (F) located on front of pump
prior to each use. CAT recommends changing oil after 50 hours
of break-in operation. Change oil every 3 (three) months or after
500 hours of use. Pump requires CAT pump crankcase oil (21oz
container), Wheeler Rex PN 276254. Add oil through pump
crankcase cap (E).
 Suction Hose Wheeler Rex PN 34550

Hydrostatic Test Pumps
CAUTION !!!
This pump is designed for water only!!
The pump is equipped with an adjustable pressure relief valve (C), which helps protect the system from being
over pressurized. It can be preset by plugging the end of the hose. Turn the adjusting knob clockwise to
increase pressure and counterclockwise to decrease.
