Ozone Flow Restrictor, Freshwater
Item #: 72699
A flow restrictor reduces the amount of ozone that will be sucked into the injector through the Freshwater Ozonator. Reduced flow will in turn reduce the bubble size in order to prevent a "burping" effect on some models of Hot Spring and Tiger River spas. If the ozone gas bubbles are too large, it will produce an annoying intermittent burping sound coming from the spa. The burping effect will NOT harm the spa however. This item also replaces the obsolete 72721 .
