I have a Kenmore refrigerator (model 53552200) that has incoming tap water connected to a valve near the bottom on the back of the fridge. In addition, there is an exposed 1/4" plastic water line running on the back of the fridge, from the top, down to the bottom of the unit. This line already has a coupling in the middle of it, and I want to connect my reverse osmosis water filter to it directly, thus (hopefully) bypassing the fridge's internal water filter.
Do you know if my plan would indeed bypass the internal water filter? If so, which direction is the water running in this fridge line---from bottom to top, or top to bottom?
I understand that some fridges have fake filters that can be installed so that the normally-used input valve can be used, while still bypassing the filter. I am leaning away from this solution because there is already a water line connected to the fridge, and I'd prefer to leave that alone in case it is used in the future---I'd of course turn off the incoming water to this line while my RO connection is in place. This plan of mine just avoids having to disconnect/reconnect the compression fitting several times, avoiding any potential headaches associated w/ that.
