Check valves are handy for preventing water damage to the ozone generator. For any size ozone generator, they block water from seeping back into the unit. The arrow shows the direction of ozone flow from the nozzle to the water. Ensure no water comes into your unit by replacing the plastic check valves every 6 months.
Choose your size according to your ozone generator model:
1/4″ – Aqua-Series
5/16″ – MP-Series, SP-Series, S-Series, Z-Series
Or, select the size according to the diameter of your tubing.
