MATERIALS AND TOOLS NEEDED
MATERIALS NEEDED
Pipe joints
• One roll of PTFE tape
• One can PVC primer
• One can PVC cement
• Steel clamps (optional)
Drilled wells (driven well materials are listed separately)
• One 1-1/4" foot valve (not needed for driven wells)
• One 1-1/4" PVC pipe (to attach to foot valve; needed for shallow well only)
• Rigid 1-1/4" PVC pipe and couplings to reach from bottom of well to pump
• One 1-1/4" male PVC adapter (for discharge opening)
• Well seal with vent tube
• One 1-1/4" PVC 90° elbow (to join piping from well to pump)
• One 1-1/4" male galvanized adapter (for suction opening)
Wells deeper than 25 ft (all of the above, plus:)
• An additional 1-1/4" male PVC adapter
• One 1-1/4" close nipple (to attach to foot valve)
• One 1" x 6" NPT adapter
• Rigid 1" PVC pipe and couplings to reach from the bottom of
the well to the pump
• One 1" PVC elbow (to join 1" piping from well to pump)
Driven wells
• Well point (more than one may be needed)
• 1-1/4" galvanized pipe from bottom of well to the top of well plus 1 ft (30 cm)
(if more than one well point is needed, additional piping and elbows will be
needed to join the well points together)
• One 1-1/4" galvanized 90° elbow
• One 1-1/4" galvanized nipple
• One 1-1/4" check valve
• One 1-1/4" male PVC adapter
• One 1-1/4" male galvanized adapter
• 1-1/4" PVC pipe measured from adapter connected to pump to check valve
• Restrictor valve (connected after the elbow on the pump discharge)
• Low pressure cut-off pressure switch (recommended)
Pump to tank installation
• One male PVC adapter (attached to tank); the tank fitting size depends
on the system connect on the tank
• One tank tee; size should be the same as the adapter above
• One 1" PVC elbow
• PVC piping to fit from tank tee to the elbow on the pumps discharge
and to join the service line
• High pressure safety relief valve (attached to the tank tee)
• One 1/2" drain cock (attached to the tank tee)
TOOLS NEEDED
• Round file
• Pipe clamp
• Pipe wrench or crescent wrench
• Slotted screwdriver
• Cross-head screwdriver
• Hacksaw or reciprocating saw
• 5/8" hex key or socket bit (for medium or deep well applications)
• 3/4" deep socket (for medium or deep well applications)
• Heat gun (optional)
• Tape measure
IMPORTANT INFORMATION
JOINING PIPE FITTINGS
Follow the fitting guidelines below for all attachments unless
otherwise specified.
PVC PIPE FITTINGS
When joining two PVC joints together (such as joining an adapter to a PVC
pipe), always use PVC primer to clean both pieces—applying the primer
to the inside of one joint and the outside of the other joint so the primed
areas meet. Select Method 1, 2, or 3 to affix the joints. When tightening PVC,
tighten securely, but do not overtighten or you could break the fitting.
Method 1 – PTFE tape:
Start wrapping the threads at the end of the pipe, keeping tension on the tape.
Do not let the tape hang over the edge of the adapter. Wrap in the direction of
the threads, starting from the end, for the full length of the adapter. Overlap
each wrap about 70%.
Method 2 – Using PVC cement:
just primed and join the two pieces together. Twist to the right and back to the
left to help imbed the cement between the pieces.
Method 3 – Using heat and clamps:
fitting before joining the fittings. Heat the largest fitting with a heat gun (follow
all safety instructions in the heat gun manual). This will shrink the fitting,
bonding it to the smaller joint. Once the joint has cooled down, tighten the
clamps with a screwdriver.
METAL PIPE FITTINGS
Use PTFE tape or thread compound to coat the threadings.
CHECK TO ENSURE THE JOINTS ARE AIRTIGHT.
EVEN A PINHOLE CAN PREVENT PROPER OPERATION OF THE PUMP.
SUCTION & PRESSURE PIPE
It is recommended that only new, clean 1-1/4" pipe or hose be used. If the
pump is installed any appreciable distance away from the source of water,
the suction pipe should be increased to 1-1/2". Horizontal lengths of pipe
must gradually slope upward from the source of water to the pump to
avoid air pockets in the line. Thread compound should be used on all pipe
joints and connections should be thoroughly tightened. A foot valve or
check valve must be installed and its operation should be checked since
a leak will prevent proper operation of the system. Make sure the foot
valve is located so that it will be submerged at all times. If the well cannot
supply as much water as the pump can draw, install a tailpipe up to
30 ft (9 m) long between the injector and the foot valve. As the well
draws down under heavy demand, the pump's capacity will be reduced,
and the level will not go below the foot valve, which would cause the
pump to lose its prime. If a sandpoint or driven well is used, install a
check valve next to the pump suction instead of the foot valve (see
Typical Installations Fig. 9b). All installations must have a foot valve
or a check valve in the suction pipe.
