Review: Stopped my filter from screaming like a banshee - My filter had been used for less than 10 days but on the third day of a 6 day trip it started making noises like a bear and a moose were mating (not to mention making me break a sweat from the increased resistance). I used the kit to change the o-rings and lube the various parts, and now it's smooth as butter. Easy to follow instructions, only one of the o-rings took a little effort to remove. From start to finish it took about 10 minutes.
Review: Nice small repair parts kit. - Always good to have spare parts on hand for everything.
