Replacing An Old Pump

working on pump or motor.
1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.
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.
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

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
Coupling
by the pipe and not by the threads. The ordinary fittings found in
Drive
hardware stores are not threaded all the way through the fitting and can
Point
collapse under impact. "Drive fittings" are also smoother than standard
plumbing fittings, making ground penetration easier.
2. Mount the pump as close to the well as possible.
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 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
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.

1. Mount the pump as close to the well as possible.
2. Assemble the foot valve, strainer, and well pipe (see Figure 2). Make
sure that the foot valve works freely.
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
