If you're experiencing low water pressure in your kitchen sink and dishwasher, the first thing you should check is the aerator on the faucet. This small attachment at the end of your faucet can become clogged with mineral deposits or debris, restricting the flow of water. To check the aerator, simply unscrew it from the faucet and rinse it off. If it's still clogged, you can soak it in vinegar to break up any buildup. If the aerator is damaged, it may need to be replaced.1. Check the aerator on the faucet
If your aerator is clogged, cleaning it may improve your water pressure. As mentioned before, soaking it in vinegar can help break up buildup. You can also use a toothpick or brush to gently remove any debris. Once the aerator is clean, reattach it to the faucet and test the water flow. If the water pressure is still low, there may be other issues causing the problem.2. Clean the aerator
Another possible cause of low water pressure in your kitchen sink and dishwasher is a partially closed water supply valve. These valves, usually located under the sink, control the flow of water to your fixtures. Make sure the valves are fully open and not partially closed.
