I have a Price Pfister "Marielle" Single Handle Kitchen Faucet. I need help in figuring out how to take this apart to see if anything is blocking the flow of water. The water in my sink is trickling out of the faucent by the spray hose works perfectly fine. I took off the screen thing on the end of the faucet but that wasn't the problem the water still was coming out slow. Can anyone please help?

Do you have the instructions that came with it? I may be mistaken but I think the spout unscrews.
