If you're experiencing low water pressure in your Moen kitchen sink, the first thing you should check is the aerator. This small mesh screen is located at the end of the faucet and can become clogged with mineral deposits or debris over time. This can greatly reduce water flow and result in low water pressure. To check the aerator, simply unscrew it from the faucet and inspect it for any buildup. If you notice any debris, simply clean it out with a toothbrush and some vinegar. This should improve water flow and increase the pressure in your sink.1. Check the aerator
If cleaning the aerator doesn't improve the water pressure, you may need to take it a step further and deep clean it. Soak the aerator in a mixture of equal parts water and vinegar for about an hour. This will help dissolve any stubborn mineral deposits and unclog the small holes in the mesh screen. Rinse the aerator thoroughly and reattach it to the faucet.2. Clean the aerator
Another reason for low water pressure in your Moen kitchen sink could be due to the water supply valves being partially closed. These valves are typically located under the sink and control the flow of water to the faucet. Check to make sure they are fully open and not partially closed, as this can greatly affect water pressure.3. Check the water supply valves
If your home has a water pressure regulator, it could be the culprit for low water pressure in your Moen kitchen sink.
