Product review (5 stars): Fixed my slow flow problem
Exactly what I needed.  Had some work done on my water line from the water company and the flow cut off.  I replaced a few filters and tried clearing the lines with no luck.  I did some research and found people saying replacing this unit fixed it and it did.  Took me 15 minutes to install, though I already knew how to take apart the components needed from troubleshooting.
