    Works Great-Be careful when installing

    Posted by Paul C Levy on 16th Dec 2019

    The unit is 1/3 the size of the old ozonator which is great, however, be very careful when pushing on the ejection tube, the check valve is attached directly to the unit and has a very thin connection that will/did break.
