• Fold the liner over the top of the
Waterfall Spillway (Figure 33). It is
recommended to provide some
slack in case the position of the
spillway needs minor adjustment
later in the installation.
• Using a screwdriver or awl,
puncture a small hole in the
liner through the center of the
Waterfall Spillway fitting (Figure
34). This will be your reference
point for the location of the liner
connection.
• Unfold the liner back off of the spillway and remove the
retaining nut from the Waterfall Spillway fitting. The fitting
is reverse threaded; please refer to the arrow located on
the retaining nut for proper direction.
• Center the retaining nut over the
puncture hole in the liner and
using a pen, marker, or sharp
tool such as a screwdriver, trace
a line around the inside of the
retaining nut (Figure 35).

STEP 13
CONNECT THE WATERFALL SPILLWAY
• Using a soil tamper, thoroughly
compact the soil in the future
location of the Waterfall Spillway
(Figure 30).
• Position the Waterfall Spillway in
front of the spillway rock, on top
of the liner (Figure 31). Adjust the
height of the Waterfall Spillway
to sit flush with the starting point
of the waterfall. Be sure that the
spillway is set close enough to
connect the plumbing with the
included 15' (4.5 m) of pipe.
Note:
A bed of gravel can be placed on top of the
liner, beneath the Waterfall Spillway, to provide a
suitable base and raise the height of the spillway to
the desired level.
• Level the Waterfall Spillway
(Figure 32). The spillway should be
level from side-to-side and tilted
forward a ¼ bubble to ensure
proper water flow.
