Read these answers and very confused as person just installed Culligan Whole House Water Filtration system for our well water. The small filter system HF-360A came with the size filter, P5 Level 4. (The larger housing and filter connected to this smaller housing). I've read all the boxes, manuals, install, + filter guide colored graph... and I must say it gets quite confusing regarding the filters. Why wouldn't they state P5A if that is was is needed? Is this larger filter reason the top of the cap on housing drips? Education and Knowledge please.
