Replacing
An
Old
Pump
I_WARNING] Hazardous voltage. Disconnect power to pump before
working on pump or motor.
Step 1. Drain and remove the old pump. Check the old pipe for scale, lime,
rust, etc., and replace it if necessary.
Step 2.
Step 3.
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.
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.
You have just completed
the well plumbing
for your new pump.

Installation
(Figure

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
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.
Mount
the pump as close to the well as possible.
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 threaded
pipe joints with
'Teflon _Mtape or Teflon _M based pipe joint compound
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 weft. If one well
point does not supply
enough watec consider
connecting
two or
three well points to one suction
pipe.

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.
[t 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.
