invoice/packing list.
Read All Instructions Before Beginning the Actual Pump Installation
DO'S & DON'TS FOR PUMP INSTALLATION
DO NOT begin the installation without first reading the entire instruction booklet, studying and
understanding the diagrams.
DO NOT attempt the installation by yourself.
DO NOT begin the installation of the pump without first checking the water level in your well to be
sure you have enough pipe and rod to install the pump cylinder at least 20’ below the static water
level.
DO NOT over tighten the 1 ¼” pvc piping into the pvc female pipe thread bell end of the sch. 120
plastic pipe. The pipe can be threaded with a pair of pliers or a 12” pipe wrench.
DO NOT use large pipe wrenches for the assembly of the pvc piping.
DO NOT install the pump during a thunder and lightning storm. Be aware of any overhead power
lines.
DO NOT hurry the installation of your pump. Think before you act.
DO NOT screw multiple lengths of pipe and rod together, laid out on the ground, and then try to lift
all the pipe and rod to a vertical position to lower it into the well.
DO NOT lower the pump and pipe sections into the well by the safety rope. Grab the pipe securely
with both hands and lower the pipe, cylinder and safety rope into the well 8’ at a time, using the
paddle as a stop. The safety rope should be tied off to a secure object, i.e. the well casing so that it
can be lowered slowly and safely.
If you are going down more than 14 lengths of pipe and rod, mechanical means of
lowering them into the well is recommended along with the Bison lifting tool and
adjustable rod. Gloves are recommended when handling rope.
WARNING: All pumps are shipped with a stainless steel male pipe thread hose adaptor. You may
want to check local codes to see if a hose Bibb backflow preventer should be used when
connecting a hose to the hose adaptor on the pump. CONSULT YOUR LOCAL PLUMBING CODE!!

DO read the installation instructions and study all diagrams. Begin the installation when you are
confident you understand the instructions completely.
DO have another person help you with the installation. If you are not comfortable with the
mechanics of the installation, we suggest you hire the services of a licensed plumber, pump installer
or well driller.
DO install the pipe and rod’s 8’ sections one at a time until the entire pipe and rod is installed.
DO make sure one end of the safety rope is securely tied to the cylinder and the other end to a
secure object such as the well casing.
DO turn the electricity off to the electric submersible pump before beginning the installation if you
are installing the hand pump in the same well as the electric submersible.
DO use the paddle provided to aid in the installation of your pump.
DO thread the ends of the rods together so they butt up against each other then tighten the lock nuts
with ½” & 9/16” open end wrenches.
DO use Teflon tape on any male pipe threads which are not already taped before you screw them
together.
Note: Bison Pumps and any of its affiliates will not be held responsible for defects or damage to
this product due to inexperienced or negligent workmanship during installation of the pump and
associated parts.
INSTALLATION INSTRUCTIONS
(Bison Pumps recommend two people be involved for ease of installation.)
REQUIRED TOOLS: ½” and 9/16” open end wrenches, pliers, vice grips
STEP #1 - Make sure you have read and understand the installation instructions.
STEP #2 - If you are installing the pump in a well casing specifically dedicated to a hand pump, go
to STEP #6.
STEP #3 - If you are installing your Bison Deep Well Hand Pump in the same casing as an electric
submersible pump or piping which connects to a jet pump, proceed as follows:
STEP #4 - Remove the existing well cover or well seal, whichever you may have and set it aside. *If
you have a submersible pump, be sure to shut the electricity off to the pump before beginning the
installation of the Bison Hand Pump*
If you are installing in the same casing as an electric submersible pump, in most
cases the electrical wires exit the top of the casing then run back down to the ground
with a piece of conduit. Using a bi-metal hole saw, drill a hole through the side of the
well casing 3-4” below the top of the casing then install the electrical conduit ell
(pictured –offered as an accessory by Bison Pumps).

This will allow you to pass the wire from outside the casing through the
conduit ell to the inside of the casing where you can re-connect the wires
to the submersible pump.
STEP #5 - You may need to lift your submersible pump or deep well jet assembly and
foot valve in order to pass the Bison Pump Cylinder by the Pitless adaptor (pictured) in
your well casing. To avoid this step, you may want to select a smaller Bison Pump
cylinder.
STEP #6 - Remove the Bison Pump Cylinder from the box. Remove the red plastic
plug from the pump cylinder and discard. Raise the PVC t-handle to loosen the
piston seal. Once you have released the piston seal, pump the t-handle up and down
a few times to loosen the seal. As you pump the piston, you will hear the check
valves "burp". This indicates that the check valves are functioning properly. The
plastic t-handle can be discarded at this point.
STEP #7 - Start the assembly of your Bison Pump. If you have purchased a complete kit, you will
notice the safety rope has been securely tied to the pump cylinder when you received your pump. Tie
the other end of the rope to a secure object, i.e. the well casing, temporarily. The safety rope will be
tied to the 1/4" eye bolt on the bottom of the well adaptor in step #13. (See Detail "A").
STEP #8 –Note: when you receive your rod, one of the lock nuts will already be tightened
securely. Assemble your first piece of 3/8" stainless steel rod to the rod protruding from the cylinder.
Pull the rod in the Bison Pump Cylinder all the way to the top to connect the first rod. As you
assemble the stainless steel rod, screw the rod into the coupling until the two rod ends butt up against
each other. Use pliers to lock the rods together. Be sure to tighten the 3/8" stainless steel jam nuts on
both sides of the rod coupling. We recommend as you connect each rod thereafter, thread on the Rod
Retrieval Tool to pull rod up as far as you can and connect a pair of vice grips to hold the rod in place
while you secure the coupling and tighten the lock nuts. This should be done each time. You will
notice as you assemble the rod and piping in the well, the weight of the rod may push the piston in the
pump cylinder down so the rod lowers inside the 1 1/4" PVC pipe to a point where you can't reach it
to connect the next rod coupling.
STEP #9 - Screw the PVC male end of the first 8' section of pipe into the female thread in the head of
the pump cylinder. Use Teflon tape or pipe dope compound on all pipe threads.

STEP #10 - Lower the cylinder and the first 8' section of piping into the
well. Using the slotted aluminum paddle you received with your pump,
slide it under the PVC bell end of the pipe and rest the paddle on top of
the well casing. This will hold the pipe in place while you assemble the
rod and pipe. Continue to connect the 3/8" rod sections and PVC pipe
until you have lowered all of the pipe into the well.
STEP #11 –Attach the rod retrieval tool to the last section of rod and pull all the way up. Attach vice
grips to hold the rod up from the pipe. Remove the 3/8" Allen head shoulder bolt at the top of the
handle connection to the lift rod (See Detail "A").
STEP #12 - Screw the 3/8" rod that is protruding from the bottom of the well head into the last rod
sticking out of the PVC pipe. Tighten these rods together using plier or vice grips and a 9/16”
wrench. Thread the jam nut up against the lift rod and tighten. Screw the Well Head into the PVC bell
end of the pipe. (This step is performed more easily with two people.)
STEP #13 - Tie the end of the safety rope to the 1/4" eye bolt on the underside of the well adaptor
(See Detail "A"). Set the well adaptor and pump head onto the casing, squarely and straight; then
evenly tighten the (4) stainless steel nuts on top of the well adaptor. Tighten the (4) allen head set
screws on the well adaptor to secure it to the casing. Check to make sure the pump head is square and
straight on the well casing; making sure all the bolts are tight. Place the (4) rubber boots on the allen
head set screws of the well adaptor. Reconnect the pump handle to the lift rod with the 3/8" Allen
head shoulder bolt. Ensure the set screw in the eyelet at the top of the handle is facing back towards
the handle. Do not over tighten the shoulder bolt as this will cause the pump handle to pump
hard.
STEP #14 - Pump the handle on your Bison Deep Well Hand Pump and enjoy a cold glass of water
directly from your well.
If you are currently treating the water in your home, remember that the water you pump directly
from your well is untreated water. Bison Pumps recommends that you have your water tested to be
sure that it is good quality potable drinking water.

Additional Installation Tips:
1. If you live in an area that experiences freezing temperatures, be sure to drill an 1/8" hole in the
1 1/4" PVC pipe approximately 6' to 7' below the well adaptor. If you experience freezing
temperatures that could have a frost penetration deeper than 7', drill the hole lower on the 1
1/4" PVC pipe. (See Detail "A")
2. If you experience any deficiencies or malfunction of your Bison Deep Well Hand Pump, please
call 1-800-339-2601 for assistance and answers to your specific questions or concerns.
3. Be sure to check local plumbing codes in your area to be verify that your installation
meets all code requirements.
4. You will notice a handle locking loop is attached to your pump handle along with a stainless
steel chain and hook. If you choose, you can use either a paddle lock or a cable lock to secure
the handle to the pump when not in use. Locking the handle is totally optional.
5. You will also notice that a brass hose bibb cap is shipped with the hose bibb adaptor. This cap
can be tightened to the hose bibb to keep insects out when the pump is not in use. Caution: In
the winter months, be sure to let the pump drain back completely before securing the
brass cap. You may not want to use the cap during the winter.
6. Thank you for investing in a Bison Deep Well Hand Pump.

Maximum static levels depths for the practical use of a hand pump are as
follows:
1-1/2” Cylinder; up to a 200’ static water level
2” Cylinder; up to a 200’ static water level
2 ½” Cylinder; performance equal to the 3” cylinder at the same levels
3” Cylinder; up to a 100’ static water level
1. The information in the chart is based on actual field tests and is intended as a general guide.
2. The gallons per minute (gpm) output on each cylinder size is based on the Bison Pump being
operated by a 200 lb. male, 6’ tall, stroking the handle sixty times in one minute. Over time, the
gallons-per-minute output is directly related to the physical condition of the operator.
3. The highlighted lines in the chart are approximate limits to each size cylinder (+/- 10%).
4. On static water levels 100’ and greater, the pump should be installed using mechanical lifting and
lowering devices (i.e. electric winch, manual hoist, etc.). This should be done by experienced
installers with appropriate equipment.
5. Always install the pump with safety rope properly tied off and secured. Two people are required
for most installations.
