Product review (5 stars): Whirlpool Original Equip at Fraction of the cost
Installed a Reverse Osmosis system to my refrigerator.  Water only trickled out the dispenser.  The installer advised that the filter had to be removed and a bypass cap installed.  Did not have the bypass if it came with the refrigerator so looked online and ordered this.  It is the Whirlpool original part, bought and delivered at a fraction of the cost I would have spent through the dealer.  It came quickly, packaged well and installed in seconds.  Water system now works great, full force with great fresh cold water supply.  Thanks!
