butt against each other so that the driving force of the maul is car-
ried 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.
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 slight-
ly 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 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, consider connecting two or three well points to one
suction pipe.

water level while the pump is running in order to prevent the pump
from sucking air. Install a sanitary well seal.
