BEFORE YOU INSTALL YOUR PUMP
PRE-INSTALLATION
1. A pump cannot pump air. Make sure that suction pipe has
no air leaks.
2. Long runs and many fittings increase friction and reduce 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.
3. Be sure well is clear of sand, dirt and scale which will plug pump
and void warranty.
4. Protect pump and piping from freezing. Freezing will split pipe,
damage pump and void warranty. Check locally for frost protec-
tion requirements (usually pipe must be 12" below frost line and
pump must be insulated).
5. 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.
6. No air pockets in suction pipe.
7. No air leaks in suction pipe. 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 (it allows air to be drawn
in). Jet pumps will not pump air and will not prime until all joints
are sealed properly.
8. Match pump to well. Shallow well is 25' or less to water with
pump running.(Fig. 2)
NOTICE: Flow in to well must at least equal flow out through
pump!
9. Unions installed near pump and well will aid in servicing. Leave
room to use wrenches.
10.
Pump body may explode if used as booster
pump unless relief valve capable of passing entire pump
flow at 75PSI is installed.
11. Be sure to prime pump before starting. Water acts as lubricant.
Starting without water will cause internal damage and void war-
ranty.
No air leaks.

Use teflon tape or
pipe joint compound

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 com-
pounds on pump (it may react with plastic in pump components
and cause cracking.)
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.
Overtightening may damage pump and will void warranty.
NOTICE: Install pump as close to well head as possible. Long pip-
ing runs and many fittings create friction and reduce flow.
NOTICE: For long horizontal pipe runs, install priming tee between
check valve and well head. (Fig. 6). For driven point installations
where horizontal piping is more than 25 feet long, install check
valve (Fig. 7). Be sure check valve flow arrow points toward pump.
See "Well Pipe Installation" for more information.
