PLUMBING THE SKIMMER
None of the Big Bahama Pro Series Skimmers come with a pre-drilled pump outlet. Not
having a pre-drilled pump outlet gives the professional installer the flexibility to choose which
side of the enclosure to exit and
with what size pipe.
Drill-points have been
provided on all Big Bahama
models to show the proper
location for drilling the
outlet. See Figure 8 for
drill-point locations and
hole sizes. Using the
drill-points ensures that
the pipe outlet will be
above water level.
Drill-points for the pump discharge are provided on both sides of all Pro Series
Skimmers. Cut for 2” and 3” pipe are provided on the PS15000 only.

BULKHEAD INSTALLATION
It is recommended to install the bulkhead fitting and Male Thread Adapter (MTA)
(included) before setting the FilterFalls. Big Bahama Pro Series FilterFalls are not pre-drilled
for the bulkhead fitting. Not having a pre-drilled pipe inlet gives the professional installer
the flexibility to choose which panel of the FilterFalls to enter. Drill-points have been
provided to indicate the proper height to drill for the bulkhead fitting. Information has
been provided below to show which bulkhead is supplied and what size hole saw should be
used. (Note: If you are installing a BFK100 Back Flush Kit (not included), this is a good time
to drill for the bulkhead fittings.) See the Back Flush installation instructions on page 14 for
more information.
Remove the retaining nut and plastic friction washer, leaving the rubber gasket on the
body of the bulkhead fitting. Note that the retaining nut is reverse threads. Turn clockwise
to loosen.
From the inside of the FilterFalls, insert the threaded
end of the bulkhead into the hole on the back of
the enclosure. This will sandwich the rubber gasket
between the flange of the bulkhead and the inside
wall of the enclosure. Slip the friction washer over
the threaded end of the bulkhead on the outside of
the enclosure and install the retaining nut. Tighten
the retaining nut by hand and then finish off with a
half turn from a wrench. Note that the retaining nut is
reverse threads. Turn counterclockwise to tighten.
