STEP 15
ADD WATERFALL FOAM
• The Pond and Waterfall Foam Sealant provided is used to
fill in gaps between the rocks of your waterfall. The foam
keeps water flowing over the top of the rocks. Without the
foam you will lose the impact of your waterfall, as water
travels beneath the rocks.
• Gravel can be used to disguise the foam.
• Allow foam to dry for at least 1 hour before introducing
water.
•
Unfold the liner back off
the Waterfall Spillway
and remove the retaining
nut from the Waterfall
Spillway bulkhead. Center
the retaining nut over the
puncture hole in the liner.
Use a pen, marker, or
sharp tool, to trace a line
around the inside of the
nut.
• Remove the retaining nut
and trim a hole in the liner
approximately 1/8 inch
inside of the score mark.
• Remove the outer rubber
gasket from the Waterfall
Spillway fitting. Insert the
hole in the liner over the
Waterfall Spillway bulkhead.
The liner should fit snug
around base of the Waterfall
Spillway fitting.
• Place the second rubber
gasket onto the fitting.
Note: The liner should be
located between both rubber
gaskets.
• Place retaining nut on
Waterfall Spillway and hand
tighten. The fitting is reverse
threaded, refer to the arrow
located on the retaining nut
for proper direction. Use
channel locks to tighten down
the retaining nut an additional
¼ to ½ turn past hand tight
being careful to not over
tighten retaining nut, which
could possibly crack the
plastic fittings.
• Install the MPT barb fitting into the back of the Waterfall
Spillway. To provide a water tight seal, use the included
silicone sealant on the threads of the fitting. Be careful
not to over tighten pipe fitting, which could possibly crack
the plastic fittings. The Waterfall Spillway is now ready for
the pipe to be installed and secured in place with a hose
clamp.
• Disguise the Waterfall Spillway using boulders, logs,
gravel, soil, or other creative landscape material.
