Del Big Dipper Severe Duty Ozone Hose and Check Valve Kit
9-0777-02 Big Dipper Ozone Tubing Kit, includes 10' of 7-0594 ozone supply tubing, and a heavy duty ozone supply check valve for use with larger pumps, or on commercial spas and hot tubs. Replace the ozone supply hose and check valve every 1-2 years, as it will break down and fail eventually from nitric acid. If water makes it past the check valve, it can damage your Big Dipper ozonator, and cracked ozone hose also presents an obvious problem. Used with larger pumps or for commercial applications that run ozone 24/7, or when the ozonator is installed below water level.
