Components Required:
The following components are required to plumb the pump and connecting it to the canals and
fish tank.
PLUMBING & COMPONENTS REQUIRED
32mm x 2” Male Adapter (To fit Pump)
25mm Ball Valve Single Union Solvent Socket (80%,
20%)
32mm Ball Valve Single Union Solvent Socket (Back
Pressure)
32mm Double Union (Pump Maintenance)
32mm x 25mm Reducing Bush
32mm T-Junction Solvent Socket
32mm 90° Elbow Solvent Socket
32mm PVC Pipe
Commissioning of Plumbing on Water Pump:
• Attach the 32mm x 2” Male Adapter to the
pump outlet.
• Cut a length of 32mm pipe, 600mm long
and glue it to the adapter (Yes, glue).
• Glue the union to the other end. The
reason we install a union is to disconnect
the pump from the plumbing when needed
for maintenance purposes.
• Cut a piece of 32mm pipe, 30mm long and
glue the one end into the union and the
other end into a 32mm T-junction with the
stem facing to the right.
• Cut two pieces of 32mm pipe, 30mm long
and insert it into the stem fitting a 32mm
ball valve on the other side and the other
30mm pipe on the other side of the ball
valve.
•
Take another 32mm T-Junction which will
form part of your Venturi and insert the
stem into the 30mm pipe.

• Fit a 32mm cap to the upright end of the
T-junction and drill a 5mm hole in the
cap. Insert a straw in the whole and push
it down until the end of the straw is 2/3s
passed the diameter of the stem.
• Cut a 300mm piece of pipe and insert it
into to the other end of the Venturi to
complete the back-pressure line.
• With regards to the 1 st T-Junction, plumb
it all the way using 32mm elbows and
different lengths of 32mm pipe until the
place where the DWC and Fish Tank 25mm
lines meet.
• Connect the stem of the 32mm T-junction
to the pump line.
• Insert 2 x 32mm x 25mm Reducing Bushes
on either side of the 32mm T-junction.
• Cut two 40mm long, 25mm pieces pipe and
insert it into the reducing bushes.
• Connect the two “80%/20%” 25mm
ball valves on either side of this 32mm
T-junction and connect the fish tank and
DWC lines.
Conclusion:
If all the components of the system are
connected, the system is completed. It is
important to test run the system for a week
before you add the fish. During this time,
possible leaks can be identified and fixed.
Adjust the water flows in your system to get
a good water level balance in the system. The
fish can now be stock at a stocking density of
