Product review (4 stars): Replacing filter revealed o-ring leak issue with fridge?
I think I know exactly what happened to another reviewer here, because it happened to my wife today trying to install this OEM water filter. She thought it was installed correctly, but ended up leaking water all over the fridge, out onto our (newly refinished) floors. After turning off the water and cleaning up the mess, I tried to get the filter installed myself; same leaky result. I pulled the old GE original MWF filter out of the garbage and compared the two: the GE filter had a black O-ring gasket inside the mouth and the Waterdrop one did not. I pulled the ring out of the GE filter and put it into the Waterdrop and reinstalled and now it is sealed and has no leaks. In looking at pictures of new GE MWF filters to see if this was a fault with Waterdrop's filters, I did not notice this ring inside it, which seemed odd. So I think the O-ring was attached to the tube the filter attached to originally but slipped off into the filter at some point. So I surmise the defect to be with how the GE O-ring is supposed to stay attached in the fridge, not the Waterdrop filters, and I think this same leak would've happened with a replacement GE filter if I had not moved the o-ring with it too. I'm still deducting a star for not the manufacturer not knowing this, and just because I'm generally put-off by both them and GE due to the marks in my new floor from rolling the fridge out to clean up the mess. I would purchase these again, and I'll probably pick up a few extra O-rings to have if needed.
