INSTALLATION
INSTALLATION
Thread the pump into the top of the casing of a driven well
or bolt it to the cover of a dug well.
NOTE: The base of the pump comes ready for use with a
1-1/4" pipe or it can be reduced with a bushing for use with a
1" pipe. Be certain there is a drop pipe extending down into
the well water from the pitcher pump. The cap is adjustable
for a wide range of handle positions.
Sealing Pipe Joints
Use only Teflon tape or Teflon based joint compounds
for making all threaded connections to the pump
itself. Make sure that all pipe joints in the suction pipe
are both air and water tight. If the suction pipe can
suck air, the pump will not be able to pull water from
the well.
Priming the Pump
Never operate pump dry. Operating the pump
without water may cause damage to the cup leather.
ALWAYS fill pump with water before starting to pump.
NOTICE The pump may need to be primed more than once
before you can lift water. For best operation a foot valve
should be installed at the bottom of the suction line.

The pitcher pump must be primed before lifting water
(Figure 1). Pour water in the top of the pitcher pump until it
runs out of the spout. Wait 5 minutes until the cup leather
swells enough to make contact with the pump wall. If nec-
essary, add more water.
