Tighten flange screws with a hand held screwdriver only. Over tightening the screws
could strip out the inserts or crack the liner flange. The screws need only to be snug
for the silicone to make a seal.
Apply silicone on the threads of the Male Thread Adaptor (MTA). Screw the MTA into the
spinweld until tight. Use PVC Glue (not included) to glue the PVC flex hose into the MTA.

HIDING THE FASTFALLS
Position rocks on either side of the Pro Series
FastFalls, inside the liner. Start working
the rock in and around the front of the
FastFalls, building up to the lip of the
FastFalls, which will provide support
for a lip rock. The Fastfalls will support
the weight of gravel and rocks stacked
directly on top of the unit. The FastFalls
easily supports the weight, so consider
covering the whole unit with a single
sizeable overhanging capstone, or stack
individual smaller stones and gravel on
top to completely conceal the FastFalls
(Figure 17). For a ‘grown-in’ look, cover
the FastFalls with soil and plant small evergreens and perennials right on top. The raised
lip will keep the gravel or soil from washing into the water.

BOTTOM DRAIN KIT
The BD2000 Bottom Drain Kit contains all the necessary fittings to properly install a bottom
drain. 2” flexible PVC pipe must be furnished by the end user to complete installation.
The bottom drain should be installed in the lowest point of the water garden. When
installing a bottom drain in a new pond it is helpful to dig a 4” deep trench from where the
bottom drain pipe will enter the pond to the intake screen location. The liner can then be
installed and depressed into the trench. The bottom drain pipe can then be nestled in that
depression and easily camouflaged with gravel and stone.
Drill-points have been provided on all compatible Skimmer models to show the proper
location for the bulkhead fitting. See Figure 18. Drill the hole with a 3” hole saw and install the
bulkhead following the bulkhead installation instructions on
page 7.
Install a 2” MTA into the bulkhead on the outside of the Skimmer box. Be sure to wrap all
threaded fittings with thread sealant. Next, glue a 2” elbow to one end of a 12” length of pipe
and glue the other end into the MTA with the elbow turned toward the liner. (All pipe lengths
may be adjusted to fit your particular application).
