Installation
Process C . 1 . Install a shallow well pump
(FP4155, FP4157, FP4150)
Draining For Servicing or For Winter
The pump should be drained before it is disconnected for
servicing or if it is in danger of freezing. To drain:
• Remove drain plug from bottom of pump case.
• Remove discharge tee to vent the pump.
• Drain all piping to a point 3 feet (1 meter) below
ground level.
For wells 25 feet or less in depth, the 1/2 HP FP4155, 3/4 HP
FP4157 and 1 HP FP4150 pumps are recommended. However,
the 1/2 HP FP4205, 3/4 HP FP4207, and 1 HP FP4210
convertible pumps may be adapted to shallow wells with an
ejector kit.
General Materials Required
• One can PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• One 1-1/4" foot valve
• Two male 1-1/4" PVC adapters
• Enough rigid 1-1/4" PVC pipe and couplings to reach from
bottom of well to pump
• One well seal with vent plug
Reminder: All joints and connections must be airtight . A single pinhole leak will prevent the
proper operation of the pump . Use thread compound on all threaded connections unless
1. Thread 1-1/4" male PVC
adapter into foot valve. Hand
tighten, then tighten 1/4 turn
with crescent wrench. Seal
the threaded pipe joints with
Teflon™ tape or Teflon™
1
based pipe joint compound
approved for use on PVC.

2. Subtract five feet from the depth of
your well (see page 2 "Determine
the Depth of Your Well"). This is
the total length of rigid PVC pipe
and couplings to cement onto the
1-1/4" male PVC adapter. Cement
one section of rigid PVC pipe to the
PVC adapter which is connected
to the foot valve, then lower the
whole assembly into the well, foot
valve first. Firmly clamp the end
of the rigid PVC pipe with a pipe
clamp to prevent the assembly
from sliding down into the well.
