Low pressure at kitchen sink

Been having a problem with the water pressure being very low at our kitchen sink. The sprayer seemed good, so we figured the faucet was to blame. Since we've been wanting a new one anyhow, we purchased one to replace the one faucet.

Installed the new faucet, and the pressure is still very low. I've checked, and there aren't any pipes leaking. It's both hot and cold that are a problem, and every other faucet in the house has good pressure. Where should I start looking for the problem?

First I would remove the aerator from the end of the spout and see if the "pressure" improves. If it's good then it may just be the flow rate of a modern low flow faucet you don't like. Depending on what faucet you have there may be other flow restricting devices in the faucet.

If it doesn't then I'd disconnect the water supply lines at the faucet and put the ends in a bucket. Turn on the shutoff valves. Do you get a strong stream of water? If the stream is strong from the supply lines then the problem is somewhere in the faucet. If the stream is weak then there might be a restriction in your shutoff valves or the pipes feeding that sink.

1st faucet was 2 handle, 2nd faucet was a single. With the old faucet it was slowly getting worse, and we thought it was the faucet itself. Since the old lady has been wanting a new one, we figured it was a perfect time to upgrade, but the problem is still there.

It's taking around 25 seconds to fill a drinking glass, very low flow. Have not tried disconnecting the lines and checking flow that way yet, but it's both hot and cold, and only at that faucet. Finally have a day off tomorrow, so I'll check it, and report back.

Steel plumbing for supply lines?
Whens the last time the stops (the real name for the shut off valves) have been replaced?

Found the problem. The 1st faucet was almost plugged shut with calcium deposits, and the 2nd faucet was defective. Returned it and bought an American Standard faucet from Lowes, and it's working great.

Thanks to everyone for all the help.

I saw a bar faucet in a home recently with an aerator so badly blocked, water would not come out at all.
It surprised me that it wasn't the water lines or valves.
