pump body does not take the weight of piping or fittings.

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 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
slightly 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 PTFE pipe thread sealant tape. 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.

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