Installation
Process C, continued .
4. HOLD THE PIPE, remove pipe clamp
and slide well seal over rigid PVC
pipe and onto well casing. Position
assembly so that twelve inches of
rigid PVC pipe protrude from well
seal. Alternately turn bolts on well
seal clockwise until rubber gaskets
are tight against well casing and rigid
PVC pipe.
5. Cement 1-1/4" PVC elbow onto
rigid PVC pipe protruding from well
seal. If desired, some length may
be cut off of rigid PVC pipe before
cementing elbow. Smooth the inside
of any rigid PVC pipe that has been
cut with a round file or knife.
6. If you are using the FP4155, FP4157,
or FP4150 pump, thread a 1-1/4"
male PVC adapter into the front of it.
Hand tighten, then turn 1/4 turn with
crescent wrench. Seal the threaded
pipe joints with Teflon™ tape or
Teflon™ based pipe joint compound approved for
use on PVC.
Priming Shallow Well Jet Pumps
Steps 7–12 are for FP4205, FP4207, and FP4210
convertible pumps . See kit instruction sheet .
7. Open ejector kit.
Replace nozzle #3
with nozzle #2 (from
kit) and tighten until
snug. Thread shorter
venturi tube into
ejector until snug.
Place gasket over
venturi tube so that
openings in gasket line up with openings in ejector.
8. Slide bolts through the bolt openings
on either side of the ejector, through
the gasket and bolt ejector to front of
the pump. Tighten bolts securely.
9. Thread a 1-1/4" male PVC adapter
into front of ejector. Hand tighten,
then turn 1/4 turn with wrench.
Seal the threaded pipe joints with
Teflon™ tape or Teflon™ based pipe
joint compound approved for use
on PVC.

10. Cement
as many
sections and
couplings
of PVC pipe
needed to
connect the
PVC elbow to the 1-1/4" male PVC adapter in the front of
the pump.
11. Apply 2-3 wraps of Teflon™ tape to
the male threads on the discharge
tee. Using pipe wrench, thread 1"
discharge tee into top of pump.
Remove pressure gauge plug from
top of discharge tee. TO PRIME: Put
a garden hose into top of discharge
tee and fill pipes and pump until water overflows
from top of discharge tee. This may take several
minutes.
12. Thread pressure gauge and plug
into discharge tee. Make sure all
connections are tightly sealed.
13. Complete all electrical connections as described on page 4.
Sealing Pipe Joints
Use only Teflon™ tape or Teflon™ based joint compounds
for making all threaded connections to the pump itself. Do
not use pipe joint compounds on plastic pumps: they can
react with the plastic in pump components. Make sure that
all pipe joints in the suction pipe are air tight as well as
water tight. If the suction pipe can suck air, the pump will
not be able to pull water from the well.
14. Screw 1" male PVC adapter
into discharge tee outlet.
15. Thread 10" x 1" nipple into
pressure tank. Thread tank
cross into nipple so that the
two 1/4" holes in tank cross
face upward. Plug two outlets
on tank cross with two 1/4"
plugs.
16. Thread 1/2" boiler drain into
front of tank cross. Thread 1"
male PVC adapter into inlet
side of tank cross. Connect to
household plumbing.
