The Eco-Rise System
Plumbing the PV7500 (Eco-Rise System)
The PV7500 comes pre-drilled for use with the Eco-Rise Diverter for multiple
features or 11/2” pipe for a single larger feature.
If multiple pumps are needed, the other side
will need to be drilled. Bore a 23/8” diameter
hole using the molded drill point as a guide.
Eco-Rise Diverters mount in the molded
pockets on the neck of the PV7500 Pump
Vault. Either one or two may be used, but
each should be plumbed to its own pump.
Insert the Diverter into the hole in the pocket
and secure with the supplied hardware.
Next install the pump and Triton Check Valve,
following the instructions included with the
Check Valve. Cut the Check Valve discharge
pipe at Perfect Cut Line B for TT1500, TT2000,
TT3000 and TT4000. Determine whether
you need the 2” outlet fitting for the Eco-Rise
Diverter or the 11/2” outlet fitting for 11/2” pipe.
Set the finished assembly in the Vault and
attach to either Diverter or pipe. See page 9
for Perfect Cut Chart.
The AF1000 Automatic Fill Valve is optional
but strongly recommended to keep the water
level in the reservoir safely above the pump,
avoiding pump burnout. Mounting locations
are provided on either side of the PV7500.
Follow the Auto Fill instructions to install.
Excavating and Setting the PV7500 (Eco-Rise System)
The size of the reservoir depends on the size, height and number of the decorative fountain
elements. For a general rule of thumb, the basin should extend out at least twice the
height of the decorative elements in all directions. A three-foot-tall by one-foot-wide
column would require a seven-foot splash zone. The Eco-Blox reservoir only needs to be
large enough to support the decorative items. The liner can then be oversized to create
a ‘splash skirt’ around the basin to recapture as much water as possible with minimum
additional excavation.
Once you have determined the size and shape of the reservoir, lay out the Eco-Blox and
Pump Vault. The Vault should be placed at the perimeter of the excavation where the lid
can be accessed easily, typically closest to the electric service. Make sure the pump cord
will reach.
After determining the size and shape of the reservoir, excavate at least a foot wider and
longer than required to leave room for backfilling. Excavate the entire area of the basin to a
depth of 13”. This will accommodate one layer of Eco-Blox Small plus the gravel to hide the
reservoir. Dig the area where the PV7500 Pump Vault will sit 71/2” deeper to accommodate
it. The additional depth will help ensure the pump remains completely submersed. Level
and tamp the bottom, then cover the bottom and sides with underlayment to protect the
liner, carefully working it into the corners and the deeper Vault area. Set the liner over the
