PARASKIM V VENTURI STYLE PLUMBING
Skimmer bottom is PVC plastic. Suction outlet connections are 2" slip. The venturi inlet feed connection is
1½" slip. For slip connections, apply PVC primer to both PVC pipe and socket connections. Then apply
PVC solvent cement to both pipe and socket connections. Consult solvent cement manufacturer for correct
solvent cement for pipe used. Assemble joint per cement manufacturer’s instructions. Allow at least three
(3) hours before pressure testing.
PLUMBING: Venturi Style, Fig. 2
1. Set the venturi skimmer level as you
would install a conventional skimmer.
The skimmer face must be set a
minimum 2" back from the interior of the
concrete shell.
2. Optional SUCTION LINE – If used the
bottom suction line from the skimmer to
the pump inlet must be plumbed with 2"
Schedule 40 PVC. Plug the external 2"
port of the unused 2nd bottom 2" suction
line. If unused plug both bottom 2" ports.
3. RETURN VENTURI LINE - Water
is directed to the venturi nozzle in the
skimmer by installing a 1½" schedule
40 PVC valve controlled line from the
return manifold to the bottom 1½" port
of the skimmer. This valve is set during
normal operation of the skimmer to use
about 8-10 GPM through the Dual-
venturi nozzle.
NOTICE
Pool/Spa Installation
Be sure to plumb the venturi line control
valve on the pool return line side of a
pool/spa installation. Failure to do so will
cause the spa to drain.
NOTICE
Pool only installation.
Always plumb the venturi line control
valve immediately after the filter unless
there is an Ultra UV2 on the system.
The venturi line control valve must be
plumbed after the Ultra UV2, which is
plumbed after the filter.
4. VENTURI POOL RETURN - Glue
an 18" length of 2" Schedule 40 PVC
into the side front discharge port of the
skimmer and cap the end to prevent
gunite from entering. Do not reduce
the venturi pool return line.

result in DE being blow out into the pool.
