Plumb the inlet of the venturi to the booster pump which is connected to the return line of
the pool after all other pool components such as heaters etc. Use at least 2 inch PVC
pipe for this connection. It is recommended that a valve be installed at this connection
so that the system can be isolated from the pool.
Plumb the outlet of the venturi to the return line of the pool 18
inches after the inlet plumbing connection. Use at least 2 inch
PVC pipe for this connection. It is recommended that a valve
be installed at this connection so that the system can be
isolated from the pool.
