DRIVEN WELL
(with check valve and well point)
4. Drive the well point into the ground according to the instructions that
come with the well point. It must be deep enough to bore through
the water bearing formation below the water table but should not
exceed 25 ft (7.6 m) in depth. An individual well point may not supply
the amount of water needed. Sometimes it is necessary to use more
than one well point to increase the water supply. The two separate well
points can be jointed together using additional piping and a cross joint
(see Fig. 8)
5. Plan to have at least 1 ft (30 cm) of pipe protruding from the ground.
The rise pipe should be galvanized pipe in approximately 5 ft (1.5 m)
sections. This makes it easier to hand drive. Use as much pipe and as
many drive couplings as it takes to both reach the water and account for
the 1 ft (30 cm) of pipe protruding from the ground.
6 Attach a 1-1/4" galvanized elbow onto the pipe protruding
from the ground.
7. Attach a 1-1/4" galvanized nipple to the 1-1/4" galvanized elbow.
8. Attach a 1-1/4" check valve to the 1-1/4" galvanized nipple.
9. Attach a 1-1/4" male PVC adapter to the 1-1/4" check valve.
10. Install the pump in a clean, dry, and ventilated location that 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.
11. 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).
12. Attach a 1-1/4" male galvanized adapter into the pump suction inlet.
Do not overtighten, as this could crack the fitting. Measure from this
adapter to the check valve that was installed in step 6. Cut 1-1/4" PVC
pipe to this measurement. Using a round file, 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 may damage the impeller. Attach the 1-1/4"
PVC pipe to the adapter and then to the check valve. Check thoroughly
for any leaks. All connections and joints must be airtight. A pinhole
leak can prevent proper operation of the pump.
13. Driven well water levels may, at times, be too low to pump up. To
prevent damage to the pump, have an electrician replace the pressure
switch with a low pressure cut-off switch.
14. Follow the Pump to Tank Installation procedures.
15. Verify everything has been completed using the Installation Checklist
provided in this manual.
