Dig the entire basin down to 20" below grade

and carefully level and tamp the bottom of the

excavation. This depth ensures the plumbing

fittings exit out on top of the Eco-Blox.

Install the underlayment and liner, then the

Eco-Blox and PV1700. An additional layer

of underlayment may be added for

greater security.

Backfill the space between the Eco-Blox 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 PV1700 (Eco-Rise System)

The recessed panels on the front right and left are designed to accommodate up to two

optional Triton 3-Way Diverters, to allow plumbing and individual valving of up to six

separately controlled decorative elements. To install, drill a 2¼" hole with a hole saw (not

included). The center point of the hole is marked on the panel.

The center raised area on the front of the PV1700

can be drilled for a single discharge of up to 1½" PVC

pipe. Your pipe size will determine the size of the

hole to drill. The flat panel on the back is designed

to accommodate an overflow. The two drill points

near the top of the left and right sides are for the

installation of an Auto Fill (See Auto Fill instructions

on pg. 10).

Excavating and Setting the PV1800/PV2300

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".
