Installation
Process C. 2. Install a deep well pump
(123353, 123355)
DEEP WELL PUMP INSTALLATION
(4" DIAMETER CASED WELL)
For wells over 25, but not exceeding 70 feet in depth, the
1 HP 123353 Convertible Deep Well Pump is recommended.
However, the 1/2 HP 123355 Deep Well Pump may also be used
for depths not exceeding 70 feet.
General materials needed for either of the convertible pumps:
• One can PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• Two 1" female PVC adapters
• Enough rigid 1-1/4" PVC pipe and couplings to reach from
bottom of well to pump (delivery pipe)
• One 1-1/4" PVC elbow
• One 1-1/4" male PVC adapter
• One pressure regulator Kit (includes fittings, tubing, and
1/4" 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
TO INSTALL THE 123353 and 123355
CONVERTIBLE:
1. Thread 1-1/4" close nipple into foot
valve. Thread the other end of 1-1/4"
close nipple into bottom of ejector.
Hand tighten, then tighten 1/4 turn
with pipe wrench.
2. The ejector has two holes in the top of
it. Thread deep well venturi tube (part
#2 – longer tube) into larger hole on
top of the nozzle until snug. Thread 1"
x 5" nipple into smaller hole. Only hand
tighten venturi tube. Hand tighten
nipple 1/4 turn with pipe/crescent
wrench.

EJECTOR
1-1/4"
CLOSE
NIPPLE
FOOT
VALVE
• One pressure gauge
• Two male 3/4" PVC adapters
• Enough rigid 3/4" PVC pipe to reach from pump to pressure
tank to service line
• Tank tee (for pre-charge pressure tanks)
• Two 1/4" plugs
• One 1/2" drain cock
In addition to General Materials for Convertible Pumps
• One 1-1/4" foot valve
• One 1-1/4" close nipple
• One ejector kit FP520-100-P2
• One 1" x 5" nipple
• One 1-1/4" female adapter
• One well seal
• Enough rigid 1" PVC pipe and couplings to reach from
bottom of well to pump (pressure pipe)
• One 1" PVC elbow
• Two 1-1/4" male PVC adapters
• One 1" x 4" nipple
3. Thread a 1-1/4" male PVC adapter
over the venturi tube and into
ejector. Thread a 1" female PVC
adapter onto the 1" x 5" nipple. Hand
tighten adapters 1/4 turn with pipe/
crescent wrench.
4. Subtract five feet from the depth of
your well. This is the total length of
PVC pipe and couplings to cement
onto both 1-1/4" male and 1" female
PVC adapters. Cement a section
of PVC pipe to each adapter, then
lower the whole assembly into the
well, foot valve first. Firmly clamp
the end of the PVC pipes with a pipe clamp to prevent the
assembly from sliding down into well.
