    Works great like the OEM. Since manufacturer recommends replacing one a year these will keep system working properly.

  3. I got a bad one 2 Star Review

    My ozone generator worked for a few days then stopped. After troubleshooting, I found the check valve was bad not allowing ozone through into venturi. Replaced and worked again...Had to go buy more clamps to fix so kind of a pain for a brand new unit.

    UPDATE: It is incredibly rare for a 7-1140-07 Check Valve for Pools to be bad. We sent the customer a new one. If YOU have a bad one, let us know!
