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

(see Figures 4 and 5). Connect the pipe from the well to the pump
suction port, using the fewest possible fittings – especially elbows –
as fittings increase friction in the pipe.
• The suction pipe should be at least as large as the suction port on
the pump (include a check valve – see Figures 4 and 5).
• 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 teflon tape or pipe joint com-
pound approved for use on PVC. Joints must be air- and water-
tight. If the suction pipe can suck air, the pump cannot pull water
from the well.
hold piping. The discharge piping must be at least as large as the tank
tee. Install a relief valve in the discharge pipe capable of passing the
entire pump flow at 75 psi. Run a pipe from the relief valve to a floor
drain or some other convenient place to carry off the water.
