COR PUMP
The COR pump may be installed for use either submerged (in sump) or externally-
plumbed. An extensive discussion of aquarium plumbing design, PVC plumbing
cementing, etc. is beyond the scope of this user guide; however, some tips and
suggestions are provided here. If you need assistance with plumbing design or
assembly, enlist the help of a local aquarist or an aquarium design, installation, and
maintenance professional.
Submerged/In Sump Installation
It is highly recommended that your return plumbing has 1-
1/4” piping and
fittings to obtain the most flow from your COR pump. Smaller diameter piping
will reduce the overall flow of water.
❖
If your tank return piping is 1-
1/4”, use the included 1
-
1/4” u
nion.
❖
If your tank return piping is 1” diameter, use the included 1
-
1/4” union and a 1
-
1/4”
to 1” slip x slip
PVC reducer fitting (not included).
❖
Do not use the small orange O-ring on the pump if using the 1-
1/4”
union.

❖
If your tank return piping is ¾”
or smaller, use the smaller 1-1/4
” x ¾” slip
adapter and the smaller orange O-ring.

Slip Adapter Mounted on COR output
❖
It is recommended that you install the outer collar part of the 1-1/2
” x 1” slip
adapter on the intake threads, as this will provide protection for those threads.
Do not use the inner
1” slip part of the adapter, just
use the outer collar.
