Before You Install Your Pump
Pre-installation
1. Long runs and many fittings increase friction and re-
duce flow. Locate pump as close to well as possible.
Keep pipe straight and angled up to pump. Use as few
elbows and fittings as possible. Support weight of pipe.
2. Be sure well is clear of sand, dirt and scale which will
plug pump and void warranty.
3. Protect pump and piping from freezing. Freezing will
split pipe, damage pump and void warranty. Check
locally for frost protection requirements (usually pipe
must be 12" (30.5 cm) below frost line and pump must
be insulated).
4. Be sure pipes and foot valve are clean and in good
shape. Leaking foot valve due to dirt or scale may
allow pump to lose prime and cause pump failure.
5. No air pockets in suction pipe.
6. No air leaks in suction pipe. A pump cannot pump air.
Use Teflon tape or Plasto-Joint Stik to seal pipe joints.
Do not use pipe joint compound. (Fig. 1).
NOTICE: A leak in suction may not drip but still draw
in air. Jet pumps will not pump or prime until all joints
are sealed properly.
7. Match pump to well. Shallow well is 20' (6 M) or less
to water with pump running. (Fig. 2)
NOTICE: Flow in to well must at least equal flow out
through pump! See Performance Chart.
8. Unions installed near pump and well will aid in ser-
vicing. Leave room to use wrenches.
9.
Pump body may explode if used as
booster pump unless relief valve capable of passing
full pump flow at 75 PSI is installed.
10. Be sure to prime pump before starting. Water acts as
lubricant. Starting without water will cause internal
damage and void warranty.
Pump/Piping Installation
Pump Installation
NOTICE: Use Teflon tape supplied with pump for making
all threaded connections to pump itself. Do not use pipe
joint compounds on pump (may cause reaction with
plastic in pump components.)
1. Bolt pump to solid, level foundation.
2. Support all piping connected to pump to prevent pump
breakage.
3. Wrap 1-1/2 to 2 layers of Teflon tape clockwise (as you
face end of pipe) on all male threads being attached to
pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not
overtighten. This may cause damage to pump and void
warranty.
NOTICE: Install pump as close to well head as possible.
Long piping runs and many fittings create friction and
reduce flow.
NOTICE: For long horizontal pipe runs, install priming tee
between check valve and well head. For driven point
installations where horizontal piping is more than 25 feet
(7.6M) long, install check valve. Be sure check valve flow
arrow points toward pump.
See “Well Pipe Installation” for more information
Pressure Tank Connection
Pressure Tank
Hazardous pressure. To avoid tank blowup,
install relief valve capable of passing full system flow at
75 PSI.
PRESSURE TANK provides reservoir of water under pres-
sure and maintains cushion of air pressure to prevent pipe
hammering and possible damage to plumbing
components. When water is drawn off through house
fixtures, pressure in tank is lowered and pressure switch
starts pump.
Standard Tank Connection
When standard tank is used, air volume control (AVC) adds
air to the tank when needed. To connect AVC to pump,
remove 1/8" pipe plug from pump body near suction port
(Fig. 3). Thread 1/8" compression fitting into tapped hole.
Cut tubing to length to reach AVC; assemble to fitting on
pump and to AVC on tank. See installation instructions
provided with tank and AVC for details.
Pre-Charged Tank Connection
When pre-charged tank is used, no AVC is necessary. Pre-
charged tank contains factory provided air charge. See tank
owner’s manual for instructions on checking tank air
charge. An annual check on tank charge is recommended
to prevent excessive running of pump.
