Discharge Hose 1/4” ID x 10’ Long
Pressure Feed Method: (Preferred Method #1)
This is typically a residential water source with about 40 to 60 psi
1. Connect water supply hose to the garden hose inlet connection (E) on the pump.
2. Open valve and turn supply water on.
3. Purge the pump and pressure hose of all air. (You may have to pump the handle (B)
a few times to get the water to flow out.)
4. Connect output (pressure) hose between pump (F) hose adapter and water line (or
vessel) being tested. (Water line or test vessel should be pre-filled with water before
the test pump is attached.)
5. Purge water line (or vessel) of all air at the highest point of the system.
6. Bring water line (or vessel) to pressure by quickly pumping handle (B).
7. Watch the gauge while pumping. As you reach the desired pressure; on the
downward stroke turn the valve (C) to the ‘off’ position. If pressure drops off, there is
a leak in the line.
Gravity Feed Method: (Preferred Method #2)
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. Follow the “Pressure Feed Method”
steps 1 through 7 (listed above)

Siphon Method
Use a clean water source
1. Fill the water line to be tested.
2. Fill the intake hose (hose is not supplied, require PN 34550) with water, then quickly
place the hose into a bucket and start pumping handle. (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 5 through 7 above.
Pre-Setting Your Pump
Your pump can be pre-set to a specific pressure easily by adjusting the pressure relief valve.
1. Unscrew (counter clockwise direction) pressure relief valve (D). (Note: the valve
assembly will not come out of the casting body).
2. Add a ball valve (not supplied with pump) to the end of the high pressure hose.
3. Follow steps 1 through 3 from the ‘Pressure Feed Method’ above.
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 (in the clockwise direction) by ¼ turn
increments as you are pumping the handle, until you reach the desired pressure.
6. Your test pump is now pre-set. This eliminates over-pressurizing the water line (or
the vessel). A B

Troubleshooting Your Pump
Test pressure not being reached:
 Possible air in 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 ‘Pressure Feed
Method’ or ‘Gravity Feed Method’ to ensure water is getting into the pump.
 Pressure relief valve not adjusted properly.
 Turn relief valve clockwise until it stops.
 Check ball is stuck (not allowing water into pump)
 Disconnect from water & drain. Rotate pump upside down and listen for
check balls to rattle inside.
 Lightly tap the casting body with a wood block. Rotate & listen for check
balls to rattle inside.
 Check O-rings for wear and or cracks. Replace if necessary with Wheeler-Rex rebuild
kit PN #29250. Lightly grease each O-ring when rebuilding.
Pump Maintenance
 Pump 50/50 antifreeze/water solution through pump after each use to avoid freezing &
check balls from sticking.
 Rebuild Kit Wheeler Rex PN 29250
 Suction Hose Wheeler Rex PN 34550
CAUTION!!
This pump is designed for water only!!
This pump is equipped with an adjustable pressure relief valve (D), which helps protect the system from
being over pressurized. It can be preset by plugging the end of the hose. Turn the adjusting knob clock-
wise to increase pressure and counterclockwise to decrease.
