I would like to say my experience with Backyardplus was very positive and smooth. Oscar is one of a kind in knowledge and easy to work with. The best part is he will call you back to explain if you have a problem. I would recommend Backyardplus to anyone that is going to try to fix their system on their own. Thank youOn 11/10/2025 by T.

Ozone Restrictor, Freshwater 3
Sku: 73808Flow restrictor for the Freshwater III ozone unit used to reduce the ozone order and/or to eliminate any “burping” noise emanating from the spa. Simply remove the air filter from your Freshwater unit and attach to this flow restrictor as shown in the picture and attach the flow restrictor to your Freshwater 3 Ozonator. Once attached, you can throttle down the ozone flow until you have reached the desired result.
