After installing this product I noticed that the water flow on the hot side has very poor water flow. And no the screen isn't clogged and excellent flow out of hoses. I checked many reviews on this faucet I discovered many folks have the same problem with this faucet. I never thought I would have to trouble shoot and try to repair a "Brand new EXPENSIVE faucet".  With the number of people having this issue you would think Pfister would fix this manufacturer defect or at least a video on how to fix this problem.
