DEEP WELL PUMP INSTALLATION
(4" DIAMETER CASED WELL)
For wells over 25, but not exceeding 80 feet in depth, the 1 HP
3114 Convertible Deep Well pump is recommended. However,
the 3105 Deep Well Pump may also be used for depths not
exceeding 70 feet.
General materials needed for the 3121, 3105 or 3114
convertible pumps
• One can PVC cement (read instructions carefully)
• One 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
• One pressure gauge
• Two male 3/4" PVC adapters
• One check valve
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 SPECIFIED OTHERWISE.
TO INSTALL THE 3105, 3114 CONVERTIBLE PUMP
Thread 1-1/4" close nipple into
STEP
foot valve. Thread the other end
1
of 1-1/4" close nipple into bottom
of twin ejector. Hand tighten, then
tighten 1/4 turn with pipe wrence.
A. Some ejectors have a factory
installed brass nozzle.
B. If nozzle is in ejector kit,
thread nozzle with small hole
into 1-1/4" opening, then
thread long venturi with small
hole for deep well into the
1-1/4" opening.
The ejector has two holes in the
STEP
top of it. Thread deep well venturi
2
tube (part #2 - longer tube) into
larger hole 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.
PROCESS B. 2. Install a shallow well convertible pump (3121)

Enough rigid 3/4" PVC pipe to reach from pump to
pressure tank to service line
Tank tee (for diaphragm tanks)
Two 1/4" plugs
One 1/2" drain cock
One 1-1/4" foot valve
One 1-1/4" close nipple
One ejector
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
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.
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.
