Product review (2 stars): Tested flow with water filter bypass plug and everything works fine without filter in system
Have used three of these, new, in last three months.  (They are supposed to last 6 months.)  Works properly for about 2-4 weeks then water flow diminished by 80%.  Tested flow with water filter bypass plug and everything works fine without filter in system.  Have not noticed anything unusual about water coming to house, i.e., water pressure low or water is dirty or cloudy.  Had assessed by appliance repair specialist and he agrees problem is with filter.  For  first 5 years of service this has not been an issue.
