REPLACING AN OLD PUMP
Step 1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.
Step 2. Install the pump in the system. Make sure that all pipe joints in the
suction pipe are air-tight as well as water tight. If the suction pipe
can suck air, the pump will not be able to pull water from the well.
Step 3. Adjust the pump mounting height so that the plumbing connections

do not put a strain on the pump body. Support the pipe so that the

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

WELL POINT (DRIVEN POINT) INSTALLATION
(Figure 1)
Drive
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 car-

ried by the pipe and not by the threads. The ordinary fittings found
Point
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.
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 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.

CASING (Figure 2)
Step 1. Mount the pump as close to the well as possible.
Step 2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make

sure that the foot valve works freely.

Step 3. Lower the pipe into the well until the strainer is five feet above the
bottom of the well. It should also be at least 10 feet below the well's
water level while the pump is running in order to prevent the pump
from sucking air. Install a sanitary well seal.
