Product review (3 stars): Second potential problem LG BYPASS plug
For those who commented on the plug not helping to increase water flow, there is a second problem to be aware of.  Just installed 2015 LG side by side and encountered same RO filter/slow flow problem. LG tech came out and said it was the solenoid in the back of the ref. where the water line goes in that is a common problem.  I am now waiting for that to be shipped and installed to see if that will make a difference.  I will update once it is installed.
