I first thought it was the filter, so when I changed the filter only to noticed after I removed the filter that water was coming out of one of the holes the filter plugs into. So I removed the filter housing and blew compressed air in each of the holes that the water lines plugged into. To my surprise white flake chips blew out. This was calcium from the city water I use. The valves in the old housing worked a little better so I went ahead and replace the housing and all is good now. Good pressure and water flow. The big lesson I learned was to remove the screws in the back that hold the shut off valves on the back of the frig. This allowed more slack in the water lines to allow for me to pull the filter housing further out so I could remove the water lines with ease. (Note: This is a different set a valves then the ones on the filer housing) My unit allows for the filer to be removed and continue using the water. The water is unfiltered now.
