Product review (1 stars): DOESN'T WORK!
This is the first ever replacement filter for our filtration unit. It's a bare-bones basic under the sink unit. How hard should it be? Twist off the old, twist on the new. AND... NOTHING. Just a faint gurgling sound but no water comes out. Water filled the new filter but it doesn't flow out of the filter. WHY!? This is the exact same OEM filter.
So the solution is that I have to go buy a garden hose washer in order to jerry-rig this thing to work. Completely unacceptable.
