Limited Warranty
STA-RITE warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free
from defects in material and workmanship for the Warranty Period shown below.
Product Warranty Period
Water Systems Products — jet pumps, small centrifugal pumps,
submersible pumps and related accessories
Pro-Source™ Composite Tanks 5 years from date of original installation
Pro-Source™ Steel Pressure Tanks 5 years from date of original installation
Pro-Source™ Epoxy-Lined Tanks 3 years from date of original installation
Sump/Sewage/Effluent Products
Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication,
improper installation, or improper maintenance. Without limiting the foregoing, operating a three phase motor with single phase
power through a phase converter will void the warranty. Note also that three phase motors must be protected by three-leg,
ambient compensated, extra-quick trip overload relays of the recommended size or the warranty is void.
Your only remedy, and STA-RITE’s only duty, is that STA-RITE repair or replace defective products (at STA-RITE’s choice). You
must pay all labor and shipping charges associated with this warranty and must request warranty service through the installing
dealer as soon as a problem is discovered. No request for service will be accepted if received after the Warranty Period has
expired. This warranty is not transferable.
STA-RITE SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES,
INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE FOREGOING WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION EXPRESSLY PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an
implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and
You may also have other rights which vary from state to state.
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011.

REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to
pump before working on pump or motor.
1. Drain and remove the old pump. Check the old pipe
for scale, lime, rust, etc., and replace it if necessary.
2. Install the pump in the system. Make sure that all pipe
joints in the suction pipe are air-tight as well as water
tight. If the suction pipe can suck air, the pump will not
be able to pull water from the well.
3. Adjust the pump mounting height so that the plumbing
connections do not put a strain on the pump body.
Support the pipe so that the pump body does not take
the weight of piping or fittings.
You have just completed the well plumbing for your
new shallow well jet pump. Please go to Page 6 for
discharge pipe and tank connections.
WELL POINT (DRIVEN POINT)
INSTALLATION (FIGURE 1)
1. Drive the well, using “drive couplings” and a
“drive cap”. “Drive fittings” are threaded all the way
through and allow the pipe ends to butt against each
other so that the driving force of the maul is carried
by the pipe and not by the threads. The ordinary
fittings found in hardware stores are not threaded
all the way through the fitting and can collapse
under impact. “Drive fittings” are also smoother
than standard plumbing fittings, making ground
penetration easier.

2. Mount the pump as close to the well as possible.
3. Use the fewest possible fittings (especially elbows)
when connecting the pipe from the well point to
the pump suction port. The suction pipe should be
at least as large as the suction port on the pump
(include a check valve if your pump is not equipped
with one – see Figure 1). Support the pipe so that
there are no dips or sags in the pipe, so it doesn’t
strain the pump body, and so that it slopes slightly
upward from the well to the pump (high spots can
cause air pockets which can air lock the pump). Seal
the suction pipe joints with PTFE pipe thread sealant
tape. Joints must be air- and water-tight. If the suction
pipe can suck air, the pump cannot pull water from
the well. If one well point does not supply enough
water, consider connecting two or three well points
to one suction pipe.
You have just completed the suction piping for your
new shallow well jet pump. Please go to Page 6 for
discharge pipe and tank connections.
CASED WELL INSTALLATION, 2” OR
LARGER CASING (FIGURE 2)
1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (see
Figure 2). Make sure that the foot valve works freely.
3. Lower the pipe into the well until the strainer is five
feet above the bottom of the well. It should also be
at least 10 feet below the well’s water level while the
pump is running in order to prevent the pump from
sucking air. Install a sanitary well seal.

4. Install a priming tee, priming plug, and suction pipe
to the pump (see Figure 2). Connect the pipe from
the well to the pump suction port, using the fewest
possible fittings – especially elbows – as fittings
increase friction in the pipe (however, include a
foot valve – see Figure 2). The suction pipe should
be at least as large as the suction port on the pump.
Use PTFE pipe thread sealant tape on threaded pipe
joints. Support the pipe so that there are no dips or
sags in the pipe, so it doesn’t strain the pump body,
and so that it slopes slightly upward from the well to
the pump (high spots can cause air pockets which
can air lock the pump). Seal the suction pipe joints
with PTFE pipe thread sealant tape. Joints must be
air- and water-tight. If the suction pipe can suck air,
the pump cannot pull water from the well.

INSTALLATION FOR SURFACE WATER
(FIGURE 3)
1. The pump should be installed as close to the water as
possible, with the fewest possible fittings (especially
elbows) in the suction pipe. The suction pipe should
be at least as large as the suction port on the pump.
2. Assemble a foot valve and suction pipe (Figure 3).
Make sure that the foot valve works freely. Use PTFE
pipe thread sealant tape on threaded pipe joints.
Protect the foot valve assembly from fish, trash, etc,
by installing a screen around it (see Figure 3).
3. Lower the pipe into the water until the strainer is
five feet above the bottom. It should also be at least
10 feet below the water level in order to prevent the
pump from sucking air.
4. Install a priming tee, priming plug, and suction pipe
to the pump (see Figure 3). Support the pipe so that
there are no dips or sags in the pipe, so it doesn’t
strain the pump body, and so that it slopes slightly
upward from the well to the pump (high spots can
cause air pockets which can air lock the pump). Seal
the suction pipe joints with PTFE pipe thread sealant
tape. Joints must be air- and water-tight. If the suction
pipe can suck air, the pump cannot pull water from
the well.
