As 5picker says....did they bypass it, cause a great many of us have. A search on the topic here will give you hours of reading material where people have had trouble with those filters getting undone, hearing a thump in the middle of the night to find water leaking from the filter.
I have had 2 trailers now with that filter, and it's the first modification I made before ever running water through the units, bypassed it and use a filter outside instead...it can leak all it wants out there, at least it won't do damage.
