SP1600/SP1900/SP2600/SP3800 FastFalls Installation
Setting the Fastfalls
Place the FastFalls on a level bed of undisturbed soil if possible, to avoid settling. If
installing above existing grade, compact the area thoroughly. This critical step will ensure
that the FastFalls will not settle out of level over time. Blocks or bricks set on virgin soil can
also be used to raise the FastFalls while reducing the chance of settling.
Place the FastFalls right at the basin’s edge to create a single dramatic fall, or pull the
FastFalls back from the edge to create a stream. Leave plenty of liner around the FastFalls to
make it easy to camouflage with rock later.
To ensure a leak-proof installation, test place the FastFalls in the desired location and level it
from side-to-side and front-to-back. The closed design of the FastFalls ensures that water
will only exit the unit over the spillway, so there is no need to tilt the FastFalls forward.

Plumbing the PV15000 Pump Vault
Atlantic’s PV15000 Pump Vaults do not come
pre-drilled, allowing the professional installer to
customize the tubing size and port locations to
any application, with multiple drill points and
flat panels. The top of the Vault accommodates
Auto Fill and overflows. Flat panels at the bottom
accept 3” bulkheads for waste drains and
custom plumbing applications. Decide on the
configuration that best suits the application, then
install the pump, plumbing and Auto Fill (optional,
see auto fill manual for installation instructions)
before placing the completed vault assembly in
reservoir.
FastFalls Liner and Plumbing
Attachment
Hold the liner up against the flat panel on the back of the
FastFalls enclosure. Leave some excess slack in the liner below
the inlet. This will help alleviate any future strain on the liner connection. Make sure the
back surface of the FastFalls, and the back side of the liner is clean and free of debris. Once
you are satisfied with the position of the liner, lower it down and prepare to apply the
silicone sealant.
When you are satisfied with the placement of the
FastFalls, remove the unit and install the liner and
underlayment, being careful not to disturb the
level base. Place the FastFalls on top of the liner
in its original position. Check the unit for
level to ensure that nothing has changed.
