threads of the fittings, in order to
help provide a watertight seal.
• Now it’s time to position the
BIOFALLS
®
filter in the desired
location. The BIOFALLS
®
filter
should be set at or slightly below
the grade of the yard. Simply
remove a section of sod or a few
inches of soil in order to create a
firm foundation for the BIOFALLS
®
filter to sit.
Design tip - Keep the waterfall
to the scale of the yard! The goal
should be to create the perception
that Mother Nature herself has in-
stalled the waterfall. Avoid creating
a “volcanic look” by trying to
raise the BIOFALLS
®
filter in a
flat backyard.
• Be sure to compact the area
beneath the BIOFALLS
®
filter box
using a hand tamper or some
other heavy flat object that can
be pounded onto the soil. This will
help prevent any future settling.
• Use a 2' bubble level in order to
make sure your BIOFALLS
®
filter is
properly set into position. Your BIO-
FALLS
®
filter should be level from
side-to-side and tilt forward @1/4
of a bubble on a 2' level. This will
make sure the water comes over
the front of the BIOFALLS
®
filter
and covers the entire spillway.
(See fig. 3)
Attaching Flexible PVC Pipe
• The filter is now ready for the
flexible PVC to be glued into place
using PVC cement specified for
use with flexible piping.
• Prime the inside of the PVC fitting
and the outside of the pipe where
the flexible PVC cement will be
applied.
• After priming, apply the cement to
the fitting and the PVC pipe and
fit the two pieces together.
• Hold the pipe into the fitting (See
Fig. 4) for at least 60 seconds to
allow the glue to slightly set.
• Wait 10 - 15 minutes to let the
glue completely set before you
begin to bury the filter.
• Before you start to backfill around
the filter, install the support
racks. Otherwise, you may not be
able to get it in place. Refer to
Signature Series
™
parts diagram
on page 2.
• We also recommend having
someone stand inside the filter
to keep it in place and level while
it’s being backfilled.
• The excavated soil from the pond
can be backfilled around the
sides and back of the BIOFALLS
®
filter, creating a berm. Tamp the
soil while backfilling in order to
reduce settling. Any additional
soil can be spread around the far
side of the pond in order to create
a planting bed for perennials
and annuals.
• Double check to make sure the
BIOFALLS
®
filter is still level after
installing the plumbing.
Installing the Bulkhead
• Install the two bulkheads into the
back of the Signature Series
™
BIOFALLS
®
filter. The filter has
two openings on the back allowing
several plumbing options.
1. For single pump applications
attach one pump plumbing line
into one bulkhead and utilize
the plug in the other. Use
the angle of the bulkheads to
your advantage by using the
bulkhead that works best with
the direction and sweep of
the plumbing coming from
the pump.
2. For double pump applications,
attach each pump plumbing
line into a bulkhead.
• Optional Drain Kit – The Signa-
ture Series
™
BIOFALLS
®
filter is
available with an optional drain
kit. The drain kit is attached to
the second bulkhead on single
pump applications. The drain
kit allows the ability to conduct
water changes and makes annual
cleaning of the filter easier. (See
Installing the Drain Kit section on
this page 4)
• Install the bulkhead fitting in the
hole provided in the back of the
BIOFALLS
®
filter. The rubber wash-
er should be located on the inside
of the BIOFALLS
®
filter. Tighten the
nut on the outside until the rubber
washer begins to bulge. This
should only be approximately one
turn past hand tight. Be careful
not to over tighten the nut, which
could possibly crack the bulkhead.
Please note that the bulkhead
fitting is reverse threaded. So,
in other words, turn the nut
counterclockwise to tighten! (See
figs. 1 & 2)
• Install the PVC slip fitting into the
desired bulkhead to receive the
pump plumbing. The PVC plug
fitting provided can be installed
in the 2nd bulkhead fitting if it is
not going to be utilized. Use some
of the silicone sealant or teflon
tape (not included) to coat the
Fig. 2 Bulkhead assembly.
