Product review (5 stars): It apparently seems like a common enough problem
I just installed the filter and everything is working. Fives stars because:
- It's cheaper
- It works
- The water stream is faster
- No quality issues

I've seen some reviews where people say there hear rumbling after installing. It apparently seems like a common enough problem, and I had the same thing where:
- Water would come out, spurt, and then stop
- The fridge would rumble and make a hammering sound when depressing the water
- The fridge would rumble when making ice
- The fridge would work fine when I would put the old filter back in
Turns out, the Filter + Filter head needed to be replaced -- Part #: AP5951411, or the "Mwf Water Filter Manifold Assembly". After replacing this piece, the new filter I installed work just fine.
