If I turn on single handle faucet to high, no water flow. I hear a pipe thump but zero water. If I get a glass of water from fridge faucet water then flows out of sink faucet. It seems to work OK it I turn on very so and then inrease flow Any ideas?

Does you spray hose pull out of the faucet spout or does it sit beside the faucet.

I am pretty sure that the thump that you are hearing is the valve that make the water go to the spray hose, and if your faucet is a Moen you can call the Moen company and they will replace the faucet for you.
