It depends on how long water has been accessing the sleeve as to whether the unit still works or not. If the ballast looks rusty at all, no, it isn't going to work. If it appears fine, then there is a very good chance it will work.
As to why it happened, it could be the o rings wore out, or the seal to the quartz sleeve wore out, etc. Without more information on the age and installation of the unit, it's hard to say. There is a two year warranty on the filter. The UV portion is not available separately. For more assistance, we can be reached at 1-800-526-0650.
