The sprayer on our kitchen sink has very low pressure. Even when its trigger is fully depressed, little water comes out the sprayer, while the flow out of the main faucet is only slightly reduced. It doesn't seem like the sprayer itself is clogged (I took it off and checked). I've read that a faulty diverter valve could be causing the problem, but I don't know how to get to it. It is not obvious where it would be on this faucet design, or how the faucet should be removed to look for it. It's a Delta, and you can find a picture of it online at this URL:

Cany anyone tell me the best way to seek the diverter valve? Thanks for any help you can provide!
