SHALLOW WELL APPLICATION
SEE DIAGRAM ON NEXT PAGE
Cut the desired lenght of poly pipe to run from the top of the well to the
pumping level. Smooth the pipe cuttings with your round file. (Check that no
cut-out parts are left inside of pipe. This may block pump venturi or impeller).
Tape male adaptor threads with teflon tape and thread adaptor into the
foot valve. Slide 2 stainless steel clamps over one end of pipe and use
torch to soften pipe. Insert the male adaptor and foot valve into this pipe
end. Tighten clamps with screwdriver. For security against leaks, we
suggest to install 2 stainless steel clamps on each adaptor.

Slide 2 stainless steel clamps over the free end of the previously cut
pipe and soften pipe with your torch. Attach pipe to the well seal elbow
(end protruding at bottom of well seal). Tighten clamps with screwdriver
when cool.
Install the well seal and piping assembly into your well casing. Tight down
the seal bolts using your adjustable wrench.
To facilitate servicing at a later date, you may use a pitless adaptor and a
sealed well cap instead of an elbow and a well seal as described in steps
3 and 4.
Install your pump in the house, on a sound foundation, as close as possible
to the basement wall. Thread an adaptor into inlet using teflon tape. Do
not over tighten.
Cut the desired length of pipe from pump location to the well seal and
connect both ends using the previous way, with stainless steel clamps and
torch. Before connecting your pipe to the pump, fill the suction line with water.
Do not fill in your trench to the house until you have checked for any
leaks in your connections or trouble in your water system.
Sand or well points are limited to areas where water bearing sand or
gravel lies below the surface, and where there are no boulders or rocks to
interfere with the driving into the ground of the point.
The amount of water any ''one'' well point will supply is usually rather
limited. Sometimes, it is necessary to use more than one point to increase
the supply of water entering to the pump's suction.
THE IMPORTANT INSTALLATION STEP IN USING WELL POINTS IS THAT
A CHECK VALVE MUST BE USED IN THE SUCTION PIPE LEADING TO THE
SUCTION INLET, AS CLOSE TO THE PUMP AS POSSIBLE, TO KEEP LINE AND
PUMP WELL PRIMED.
