Product review (1 stars): Jack Hammer
Thought I would save some money and purchase these filters. It worked fine for a few days after install then came the jack hammer every time you get water and whenever the ice maker refills. Scared the crap out of my wife one night when she was in the kitchen. It is a very loud jack hammer type of sound. Can't even hear the tv in the other room when it goes off.  I tried adjusting the pressure in the back of the fridge to see if it would work and it only stopped making the sound when the water line was turned all the way to to off position. I will be going back to the OEM product.
