Shallow Well Application
(for pumping depths down to 25 ft [7.6 m])
Shallow well installations use only a single pipe connecting the pump to
the water supply. If your water table fluctuates and could reach pumping
depths greater than 25 ft, follow the instructions for deep well applications.
This pump can be used for drilled wells (see Fig. 9a) or driven wells (see
Fig. 9b). Drilled wells are holes drilled into the ground by professional well
drillers using a large rig. Driven wells use well points (also known as sand
points), which is a long pointed tube with a screen that allows water to
enter the pipe but keeps out sand and sediment. The injector assembly
that comes with the pump is pre-assembled for use in wells down to 25 ft
(7.6 m) and is installed directly on the pump.
1. Place the red rubber gasket over the venturi ensuring the hole sizes
match. Attach the injector assembly to the front of the pump casing
with the washers and bolts provided to ensure that the label marked
"Bottom" is at the bottom of the pump. (The holes on both the injector
assembly and the front of the pump should match).
2. The extra venturi and extra nozzle (if applicable) supplied in the injector
kit are not needed for this installation.
3. There are two types of shallow well installations: drilled wells (see Fig.
9a) or driven wells (see Fig. 9b). Drilled wells are holes drilled into the
ground by professional well drillers using a large rig. Driven wells use
well points (also known as sand points), which is a long pointed tube
with a screen that allows water to enter the pipe but keeps out sand
and sediment. The water level in a driven well is fairly high or near
ground level (maximum 30 ft [9.1 m]). Continue with the appropriate
shallow well installation.

4. Measure from the bottom of the well to the top of the well and subtract
5 ft (1.5 m). This is the length of 1-1/4" rigid PVC pipe and couplings you
will need from the bottom of the well to the first elbow. Cut the pipe
and use a round file to smooth the pipe cutting. Ensure the pipe is clean
and free of any pipe shavings or pieces as these could get into the pump
and damage the impeller. The remainder of the pipe will be used to
connect the pump to the well.
5. Attach the 1-1/4" male PVC adapter to one end of the rigid PVC pipe and
attach the adapter to the foot valve. Check to ensure the joints are
airtight. Even a pinhole can prevent proper operation of the pump.
6. Firmly clamp the unfinished end of the pipe with a pipe clamp 1 ft
(30 cm) from the top of the pipe. This will prevent the pipe from
dropping to the bottom of the well. Lower this section into the well
foot valve first.
7. On the end protruding from the well, which is held in place with the
pipe clamp, insert the well seal and have the pipe protrude 1 ft (30 cm)
outside of the well seal. If you have measured correctly, the foot valve
will be suspended 4 ft (1.2 m) from the bottom of the well. This will
ensure sand and sediment doesn't get drawn into the system. Install a
well vent tube in the well cap.
8. Attach the end of the pipe securely to a 1-1/4" PVC 90° elbow.
9. Install the pump in a clean, dry, and ventilated location which provides
adequate room for services and protection from freezing temperatures.
It should be bolted to a good foundation, preferably concrete, and
provided with adequate drainage. Locating the pump as close as
possible to the water source reduces the friction in the suction pipe
and will provide maximum performance.
10. If a pressure gauge is supplied with the pump or if you wish to install
a pressure gauge, it should be installed into the 1/4" NPT hole on the
front of the casing directly in front of the priming port. (See Typical
Installations Fig. 9a, 9b, 9c or 9d.)
11. Attach a 1-1/4" male galvanized adaptor into the suction inlet. Do not
over tighten as this could crack the fitting.
12. Use the remainder of the PVC pipe from step 4. Smooth the pipe cutting
using a round file. Ensure the pipe is clean and free of any pipe shavings
or pieces as these could get into the pump and damage the impeller;
connect one end of the pipe to the adaptor attached to the suction inlet.
Check thoroughly for any leaks. All connections and joints must
be airtight. A small pinhole leak can prevent the pump from
operating properly.
13. Follow the Pump to Tank Installation procedures.
14. Verify everything has been completed using the Installation Checklist
provided in this manual.
