Product review (5 stars): filter good--filter slot/housing bad
i bought this filter at a local store and had no water after slow flow---turned out it was NOT the filter causing the problem.  this design for easy replacement is bad---the problem is the filter housing in which you slide this filter---the two prongs that this filter depresses are the valves which go bad.... i ordered the filter housing from amazon, replaced it in 15 mins, flushed about 3 gallons,  and the water is perfect.  the part on amazon was w10121138 and was a genuine wp part
