I have installed a Glacier Bay pull-down faucet that came in a sink/faucet package
The item #1000 000 000. & Model #440176042.
The hot water does not flow, if at all. I took it back to Home Depot and exchanged it and the same issue is apparent. I checked the flow from the attachment from hot water value and it is strong going through the hose to faucet connection. The restriction is in the faucet in both cases. Can it be adjusted? This is becoming a pain and I have gone through this twice. I've had plumbers install it and cjange out and they say take it all back to HD, but that costs $ to remove & install a new one.
I want to make thois one work, but not sure I can.
Any suggestions?

Hard to imagine 2 are bad, as I have installed many and had no problem. Are you sure you are not kinking the hot supply riser?
