Why is my kitchen faucet constantly trickling despite replacing the water supply lines and faucet?

I just don’t know what to do. For the past few years since we moved in, our kitchen faucet has had such low water pressure. It’s strange because the dishwasher and downstairs bathroom are working just fine. I even tried replacing the water supply lines and faucet today, but the issue remains. I’m stumped as to what could be causing this.
‘t forget to monitor the pressure if you have a bladder tank.
Hey, mentioned that it’s only the kitchen faucet with low water pressure.
Do the stops require multiple turns to operate?
Mentioned they are.
Suggested switching them to 1/4 turn.
Have you tested the valve directly without the supply line connected? It’s possible the valve is defective.
I hadn’t considered that, I’ll need to disconnect the lines to see if the issue persists
It sounds like there might be a blockage somewhere, just keep tracing back to find where the pressure drops.
Also, make sure to clear out any debris in the lines when replacing an angle stop on a copper/galvanized house. Running the line without the angle stop can help with that.
Unscrew the nozzle from the hose. Turn on the water to check if the hose is flowing at full force.
Take a peek inside the nozzle – there’s a tiny o-ring washer that might be twisted and causing a blockage. Remove the o-ring and you should be all set.
The washing machine is no longer working.
Remove the aerator and give it a good clean.
Mentioned it’s a new faucet
Hey, if it’s a new one, there might be a flow restrictor inside. I had that happen with a shower head I installed, hardly any water came out. Thought it was broken at first. Also, there could be particles or something else. Just a suggestion. Try removing the aerator and see if the flow improves
What year was the house built?
The only things left to replace are the valve or the aerator. Unless, of course, you have galvanized pipes that lead to this particular fixture.
Why don’t you grab a bucket and test the water flow directly from the supply line?
Have you looked at your angle stop valves? Sometimes they can stop working and get clogged. It might be a good idea to replace both of them while you’re under there.
