• When the Pondless Waterfall
Vault is located between
two AquaBlox there will be a
void space behind the vault
that will require backfilling.
Use 1.5" or larger gravel
inside the liner, behind the
Pondless Waterfall Vault to fill
the void space (Ex. 12).

INSTALL PUMP AND
PLUMBING
• The Pondless Waterfall Vault
and extension includes one
3" hole to run the plumbing
from the pump to the start
of the waterfall. Flexible PVC
pipe can be inserted through
the hole in the side of the
Pondless Waterfall Vault and
connected to a check valve
or plumbing assembly (Ex. 13).
• Additional plumbing holes can be drilled through the
Pondless Waterfall Vault if needed. A second drill point
is located on the opposite side of the Pondless Waterfall
Vault and extension for accuracy when drilling an
additional plumbing hole.
NOTE: Larger pumps using 3" plumbing will require
the use of the Pondless Waterfall Vault Extension and
AquaBlox Large Storage Modules.
