WELL POINT (DRIVEN POINT)
INSTALLATION
(FIGURE 1)
Step 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 fit-
tings” are also smoother than standard plumbing
fittings, making ground penetration easier.
Step 2. Mount the pump as close to the well as possible
Step 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 – 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 pock-
ets which can air lock the pump). Seal the suc-
tion pipe joints with teflon tape or a teflon based
pipe joint compound. 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, consid-
er connecting two or three well points to one
suction pipe.
You have just completed the suction piping for
your new shallow well jet pump system. Please
go to Page 7 for tank information.
