Product review (1 stars): Makes Our Fridge Groan Like An Angry Ghost!
Bought a Waterdrop DA29-00020B filter a while back and every time we used the refrigerator water dispenser it made a groaning noise like the the water pump motor was having an issue. We assumed it was the refrigerator. I bought the same Waterdrop filter as a replacement and the groaning noises were gone. This time I bought the Waterdrop Plus DA29-00020B and the groaning noises are back. I sent an email to the seller and didn't receive a response. Bad customer service!
