The procedure is the same as for Eco-Blox reservoirs, but the excavation only needs to
accommodate the 9" height of the Eco-Blox Small plus another 4" for gravel, a total of
13". The area under the PV7500 Pump Vault will need to be 71/2" deeper than the rest of
the excavation. The additional depth will recess the Pump Vault lower than the rest of the
reservoir, helping the pump in the Vault to stay submerged.
NOTE: For best results, install the pump, optional Check Valve and optional Autofill in
the Vault before installing the Vault in the reservoir.
Install underlayment and liner, then install the Eco-Blox SMALL and the plumbed PV7500.
Backfill and top the Eco-Blox with gravel.

PV15000 Installation
Plumbing the PV1700 Pump Vault
The PV1700 is Atlantic's most compact, easy
to install pump vault. The PV1700 features an
incredibly strong enclosure, pump discharge step
fittings molded into each side of the enclosure with
cut lines for 1½" and 2" pump discharges, marked
drill points on the left and right sides for an Auto
Fill and a flat panel on the back for an overflow.
The step fittings allow the installer the flexibility to
exit out the left or right side. After deciding how
the Vault will be plumbed, cut off the unneeded
step with a hand saw. Assemble a TR215CV Check
Valve (refer to TR215CV manual for installation
instructions). Attach check valve to pump and place
assembly in Vault. Choose one of the drill points to
install an AF1000 Auto Fill (optional, refer to AF1000
manual for installation instructions) and place
completed vault assembly in reservoir.
