Restricted flow to kitchen faucet?

The flow of water to our kitchen faucet suddenly has been reduced by at least half.

The aerator is clean.

What is the the next step in troubleshooting this problem?

Both hot and cold?

First, make sure the shut off valves under the sink are fully open.

If it is a pull out style faucet (where you can pull the end out to use as a hand spray) disconnect the flex hose from the pull out end. There is often another screen there that can get plugged. While you have it apart, turn on the faucet and see if the flow from the flex hose seems good and strong.

If not a pull out, next step is usually to disconnect the lines feeding the faucet after turning off the water, direct them into a bucket, and turn the water on to flush the lines and check the flow. If the flow is good there, there may be a blockage in the faucet valve. If flow is bad there, then there may be a blockage in the stop valves.
