Ozone Units (Models ending in -5M04O-5M12O-5M24O)
The recirculation line is coupled in line with a Mazzei eductor. The Mazzei eductor
creates a vacuum drawing ozone from the ozone gernerating system. The line in
the tank should extend and terminate in a tee to split the flow in the tank (see page
13). The tee should be placed 20-24” off tank floor or half of the water depth. An air
sparger is not / can not be used with an ozone system. All piping containing ozone
must be PVC.
Rubber hose is not compatible with Ozone!! Ozone will eat
through rubber hoses and poly flow tubing.

4. Pump Suction Line
Connect the suction line from the last compartment
of the last reclaim tank into the basket strainer inlet
on the reclaim unit. Keep the size of the line 2” for the
PW100 / 200 / 300 units and 3” for larger units. Piping
between the tank and reclaim system should have a
minimal amount of 90’s, threaded connections and
should never go higher than the basket strainer
inlet.
The suction line within the Reclaim tank should
have a flapper type foot valve at the very end of it and a
union installed for maintenance. Unions must be above
the water level to allow removal of the suction line from
the manway to access foot valves without draining the
tank. Unions must be tight to prevent suction loss.
Do
not over tighten!
PurWater supplies two PVC flapper
check valves to attach to the suction lines. The bottom
of the valve in the tank should be a minimum of 16”
above the bottom of the tank floor.
Do not use spring
loaded check valves or valves with screens on the
suction line.
Pressure testing of both suction lines is
recommended before connecting to the reclaim unit.
Two suction lines are recommended. One is for use and
one is a spare. It is a real good idea to plumb the two
suction lines into a manifold during installation with ball
valves to facilitate making the switch from the primary to
the secondary suction line.
An example of a very effective suction line manifold
Secondary Line (BV off)
Primary Line (BV on
)
NOTE: Suction Line Height
can not be above basket
inlet!!
