Culligan CP5-BBS Whole Home Heavy Duty 1" Water Filter Replacement, Fine Filtration

Allow yourself an hour or so to change the cartridge the first time....and take your time to get it right., several buckets.., one with clean water in it, another to empty the old filter and dirty water into, and another to catch what may spill out of the unit as you unscrew the big bowl off of the bottom of the unit. A clean rag or two, some plumbers grease for the big O-ring seal... maybe a roll of paper towels and a plastic grocery bag to throw the wet dirty ones into....and you'll be all set! You'll get better and faster at it. You got to do what you got to do.....if you want clean water. [This review was collected as part of a promotion.]
