If you're experiencing low or no water pressure in your kitchen sink, the first thing you should do is check the water supply valve.

If this doesn't solve the problem, move on to the next step.Check the water supply valve
The aerator is the small device attached to the end of your faucet that mixes air with the water flow to create a steady stream. Over time, mineral deposits and debris can build up in the aerator and cause blockages that can affect water pressure. Remove the aerator and clean it thoroughly, or replace it if necessary.Inspect the aerator
Another potential cause for low water pressure in your kitchen sink is a clog in the faucet itself. To check for this, turn off the water supply and unscrew the faucet from the sink. Inspect the inside of the faucet for any debris or buildup that could be blocking the water flow. Clean or replace the faucet if needed.Check for clogs in the faucet
