One of the brackets holding the spray nozzle on broke. After talking with the factory we found out this unit has been running backwards, probably since installation. It should rotate down into the back wash headers. I have heard of more than one unit doing this and could not find any notes to check it. Has anyone else had this problem? I would recommend everyone check their unit since it does work in both directions. This broken bracket did some damage to our unit and could have torn the filter if we hadn't caught it immediately.</P><P>Let me know how many are going the right way and how many are not.</P><P>ThanksMon, 17 Dec 2007 13:00:36 GMT01667602
