Gravity Feed: (Preferred Method)
This method requires a tank with a water outlet at the bottom. The water tank’s outlet should
be level with or above the level of the water inlet connection on the pump. This allows water
to flow naturally into the test pump. Connecting a pressure fed water line is harmful to the
diaphragms in the pump.
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 (M) on the pump.
3. Open valve and turn water supply on.
4. Purge the pump and pressure hose of all air.
5. Connect output (pressure) hose connection (J) between pump 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 (I) while pumping. When
the desired pressure is achieved, turn the isolation valve (H) 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 with water, then quickly place the hose into a bucket and turn pump
on. (Unit is self-priming once primed). Continue to run pump until you see the water
coming out of the outlet hose, 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
Gravity Feed Method.

Pre-Setting Your Pump
Your pump can be pre-set to a specific pressure easily by adjusting the pressure relief valve.
1. Loosen the jam nut (G) on pressure relief valve. Then unscrew (counterclockwise
direction) the pressure relief valve knob (F) a few turns . Be sure not to unscrew the
knob too far as the knob and nut can easily be 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 ‘Gravity 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 (F) in the clockwise direction by ¼
turn increments, until you reach the desired pressure. Tighten jam nut (G) to hold at
this desired pressure.
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 through 6 of the
“Pre-setting Your Pump” section.
 If using the Siphon Method and not getting pressure, try the
‘‘Gravity Feed Method’ to ensure water is getting into the pump.
 Check strainer (F) O-Ring for cracks.
 Oil Reservoir is milky in color
 Diaphragm is cracked, causing water to mix with oil. Diaphragm
needs replaced.
 Pressure relief valve not adjusted properly.
 Turn relief valve counterclockwise and watch gauge (C) for change
in pressure.
Pump Maintenance
 Pump 50/50 antifreeze/water solution through pump after each use to
avoid freezing and to lubricate pump.
 Check strainer (F) O-Ring for cracks prior to each use.
 Check and change engine oil per manufacturers specifications.
 Gear reduction Gear Lube. Check and change per manufacturers
specifications.
 Pump repair kit (Wheeler Rex PN 36345)
 Suction Hose (Wheeler Rex PN 34550)
 Pump Oil Reservoir - Check and change per manufacturers specs.
Use 30W Non-detergent oil
Dump Valve
Dump valve is designed to dump off pressure when the test is complete..

Hydrostatic Test Pumps
CAUTION !!!
This pump is designed for water only!!
The pump is equipped with an adjustable pressure relief valve (A), 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.
