Product review (4 stars): Ice and cold water again without expensive proprietary filter purchases
I rerouted my water lines from this control to bypass the filter and found a water leak on push in fitting afterwards - disturbing lines can cause water leaks at the push in fitting (John Guest type) fitting. I was ready to buy this control to hopefully fix the leak (14 year old fridge). I tried several times to fix leak by checking o ring, making sure tube pushed in all the way and cutting tube end off square to ensure tube not scratched, etc. As a final step before ordering this control,  I went to home center store and bought a similar but different brand fitting (coupling- not John guest brand) to use the o ring in the old control- and it worked!  New o ring worked right away/ no leaks after repeated leaks trying to reuse old o rings. I replaced all 3 o rings 1/4, 1/4 and 5/16 for me. I guess o rings stiffen over the years.
