any reason you must have fittings or filters between the
pump and tank and they cause switch chatter you should
move the pressure switch to the tank cross tee. Go To

Double (Twin) Pipe Suction Piping
A double (twin) pipe jet assembly is used in wells 4" and
larger. Our 4" jet assemblies require a minimum 1
suction and 1" drive water pipe. Use of smaller piping
will reduce performance in gpm and pressure. Offsets
over 50' require larger pipes to reduce friction loss and to
obtain published performance.
Install Double (Twin) Pipe Jet Assembly
WARNING
Check to make sure the nozzle is installed in
the jet assembly. Install the venturi tube in line
with the nozzle. On 4" jets attach the 1
suction and 1" pressure pipe to the jet assembly

female threads. Install a foot valve on the male
thread bottom port on the jet assembly or on the end of a
34' tail pipe. The tail pipe prevents over pumping a low
yield well so the pump will not break suction. See Tail
Pipe in Technical Section.
Lower the jet assembly into the well. It should be set at
least 5' below the static water level. Keep the jet a few
feet off the well bottom to lessen the possibility of
sucking debris into the jet. The connections at the well
head can be either a pitless adapter or a well seal.
Priming will be easier if you fill the pipes with water
before attaching the pump.
Connect the suction and pressure pipes to the threaded
connections on the face of the pump. This can be done
using unions and threaded pipe nipples, or barbed
connectors with poly pipe. Always double clamp barbed
connectors. Make sure that the piping slopes upward to
the pump and that no point is above the pump suction.
On long offsets it is easier to prime the system if you fill
the pipes with water before connecting the pipes to the
pump. Go to Deep Well Discharge Piping.

packers only: Use the Red Jacket Water Products turned
couplings part #64655 to connect the sections of 1
threaded pipe. This special diameter turned coupling
increases the clearance between the 2" well I.D. and the
O.D. of the coupling to allow the drive (pressure) water
to easily pass the couplings. Failure to use them will have
a negative impact on pump performance, both pressure
and gpm will decrease. The pump may easily lose prime
while pumping due to the restriction!

Using smaller than recommended pipe may reduce gpm
output. The longer the pipe the worse the affect.
Install Single Pipe (Packer) Assembly
To ease installation soak the 2" or 3" packer assembly in
warm water to make the leathers soft and pliable. DO
NOT lubricate them with grease, oil, or petroleum jelly!
–
The leathers must absorb water to seal the packer
assembly against the well casing.

assembly. Install the venturi tube in line with the nozzle.

Attach Suction Pipe To Right Angle (Packer) Adapter
Single pipe (packer) systems always require a packer
adapter at the well head. The adapter makes the
transition from vertical to horizontal. See the list of
packer adapters/pump models to see which one your
pump system requires. See Chart 1 for a list of Packer
Adapters/Pump Models.
After the jet assembly is inserted into the well, attach the
Packer Adapter to the top of the suction pipe. Screw the
top section of 1
threaded adapter into the 1
in the 2" packer adapter or a 1
3" packer adapter.
Make sure that the O.D. of the well casing is free of dirt
and burrs. With the gland bolts loosened the tapered seal
ring on the packer adapter should slide over the well
casing. After insuring that it is in place tighten the two
gland nuts to compress the seal ring and seal it to the
well casing O.D.
Install the pump by attaching it to the Packer Adapter
using the bolts and gaskets provided.
