Piping
In The
Deep Well
See Figures 6, 7, and 8.
NOTICE:
Deep well installations
are either
single pipe
(2" wells) or double
pipe (4" and larger wells). In a dou-
ble pipe installation,
the larger pipe is the suction
pipe
and the smaller pipe is the drive pipe (very deep wells
may use suction
and drive pipes of the same diameter).
Plastic pipe
is ideal for double
pipe installations.
Due
to its light weight,
it is easy to handle
and does not usu-
ally require
a block
and tackle
for installation
and re-
moval.
Double
Pipe Installation
- Plastic
Pipe
NOTICE:
Use Teflon tape on all male threads
on plas-
tic pipe and fittings
to prevent
air leaks in suction
pip-
ing.
1.
Inspect
ejector
to make sure that nozzle
and ven-
turi openings
are dean and clear.
2.
Inspect pipe for any foreign matter or obstructions.
NOTICE:
Make sure that no foreign matter enters
pipe
openings
while installing
pump.
3.
Make sure foot valve operates
freely: attach
to ejec-
tor with a close nipple.
Use Teflon tape on male
threads.
4.
Install nozzle
and venturi
in deep well ejector.
5.
Using Teflon
tape on male threads,
install special
plastic
pipe
adapter
(supplied
with
ejector)
by
screwing
adapter
into 1-1/4" tapped
hole in ejector
body (see Figures 6 and 8, above).
6,
Thread
a 1" plastic pipe adapter
or a 1" nipple
into
the 1" tapped
hole in ejector
body (see Figure 8).
7.
Install sufficient
plastic pipe in well casing to place
ejector
at the proper
depth.
(Your well
driller
should
supply this information.)
NOTICE:
As a guide, the ejector
should
be set at least
10 to 20 feet below the lowest water
level with pump
running,
if possible,
but always at least five feet from
the bottom
of the well.
8.
Tighten
all hose clamps
securely
on plastic
pipe.
Use two damps
per joint to prevent
air leaks into
suction
pipe. Clamp screws
should be on opposite
sides of the pipe. Fill pipes with water to make sure
that foot valve and connections
do not leak.
9.
Install sanitary
well seal on top of well casing; use
steel nipple through well seal as shown
in Figure 6.
NOTICE:
Align locating
lugs on adapter
flange
and
pump
base so that pump
discharge
will be aligned with
piping.
10. Install 1" nipple
in one side of adapter
flange. Slide
threadiess
coupling
down
over drive
pipe
from
well. Thread adapter
flange onto suction pipe from
well and align nipple
and drive pipe.
11. Slide threadless
coupling
up and secure
nipple
to
drive pipe.
12. Remove paper backing
from adhesive
gasket. Apply
gasket to adapter
flange, making sure that holes line
up.
13. Align locating lugs on pump
base with locating lugs
on adapter
flange; attach pump
to flange with cap
screws
provided.
