Compression fitting failed after four yearsThe filter has been very good at removing the bad taste from our tap water and the cartridges are easily changed. However, last week we came home after being gone three hours to a kitchen, dining room, breakfast nook, study, etc. (all with hardwood floors) flooded. The floor is ruined and repairs will likely run several thousand dollars. I inspected the failed fitting (I am an engineering laboratory director, one part of the lab is dedicated to mechanical failure analysis) and found the compression fitting ferrule--placed inside the tubing when assembling the compression fitting--was woefully undersized at .220" for .250" tubing. The fitting is clearly faulty, I'm embarrassed I didn't note this during assembly four years ago.
