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)
Driven Wells
• Well point (more than one may be needed)
• 1-1/4" galvanized pipe from bottom of well to 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
• Heat gun (optional)
• 5/16" - 8 point socket and ratchet
• 9/16" - 8 point socket and ratchet
• Measuring tape
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. Apply 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:
Wrap PTFE tape tightly around the male
threads. 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. Starting from the end, wrap in the direction of the threads
for the full length of the adapter. Overlap each wrap about 70%.
Method 2 - Using PVC cement:
Apply PVC cement to the areas
that were just primed and join the two pieces together. Twist to
the right and back to the left to help embed the cement between
the pieces.
Method 3 - Using heat and clamps:
Add two steel clamps to the
largest 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 threading.
CHECK TO ENSURE THE JOINTS ARE AIRTIGHT.
EVEN A PINHOLE CAN PREVENT PROPER OPERATION OF THE PUMP.
SUCTION AND 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 a sand point or
driven well is used, install a check valve next to the pump suction instead
of the foot valve (see
Typical Installations
, Figure 5). All installations must
have a foot valve or a check valve in the suction pipe.
