EXCAVATING AND SETTING THE PUMP VAULT
Once you have determined a proper sized basin for your project, begin by deciding the
placement of the vault. The vault should be placed away from the waterfall where the lid can
be accessed easily. Excavate the entire area of the basin to a depth of 18”. This will
accommodate one layer of Eco-Blox. The area where the pump vault will sit should be dug
deeper to provide a sump area for the pump to sit, ensuring the pump
will remain completely submersed. If using a PV1800, dig this area
to a depth of 22”, and for a PV2300, a depth of 28”.
Pro Series Pump Vault Installation
For installations where a larger basin volume or deeper basin is required, Atlantic offers pump vault
extensions for both the PV1800 and PV2300. Each extension will add the
height of one Eco-Blox. For each additional Eco-Blox layer,
increase the depth of your excavation by 17”.
Once excavation is complete, install underlayment,
pond liner, properly oriented Eco-Blox and Pump
Vault. Backfill the space between the Eco-Blox/
Pump Vault and the excavation to lock them into
place, either outside the liner with sand or clean
fill, or inside the liner with gravel ¾” or larger in
diameter. Top the liner and basin with ¾” or
larger gravel or decorative stone.

PLUMBING THE PUMP VAULT
Atlantic’s Pro Series Pump Vaults do not come pre-drilled
for the pump outlet. Not having a pre-drilled pump outlet
gives the professional installer the flexibility to choose
which side of the enclosure to exit and with what size pipe.
Drill points and cut lines have been provided for 2” and
3” flex PVC. Two panels at the top have been left flat for
custom plumbing applications as well as the installation of
an AF1000 Auto Fill and/or overflow. Recessed areas and
cut lines for 4” and 6” SDR35 have been provided on two
bottom panels. Pipe extensions can be added to increase
the flow of water into the vault and also increase the ability
to channel debris into the vault.
