If you turn on your kitchen sink and no cold water is coming out, the first thing you should do is check the shut-off valve. This valve controls the flow of water to your sink and may have accidentally been turned off or partially closed. It is typically located under the sink and can be turned on by twisting it counterclockwise. If the valve is already open, try closing it and then reopening it to see if this helps restore the cold water flow.1. Check the shut-off valve

The faucet aerator is a small screen-like attachment located at the end of your faucet. Over time, it can become clogged with debris and mineral buildup, which can restrict the flow of water. To check the aerator, unscrew it from the faucet and clean it with a mixture of equal parts water and vinegar. Then, rinse it off and screw it back onto the faucet. This should help improve the water flow and restore the cold water to your kitchen sink.2. Check the faucet aerator

If the shut-off valve and faucet aerator are not the issue, the next step is to check the water supply line. This is the pipe that connects your sink to the main water supply. Check for any kinks, twists, or blockages in the line that could be preventing the flow of cold water. If you find any, carefully straighten or remove the obstruction and then turn the water back on to see if the cold water has been restored.3. Check the water supply line

If your kitchen sink only has one handle for both hot and cold water, the issue may lie with your water heater. Make sure the temperature on your water heater is set to the appropriate level (typically between 120-140 degrees Fahrenheit). If the temperature is too low, the water may not be heating up enough for the faucet to mix it with cold water. Adjust the temperature as needed and let the water run for a few minutes to see if the issue has been resolved.4. Check the water heater

In colder climates, frozen pipes can be a common cause of no cold water in the kitchen sink. If you suspect this may be the issue, check any exposed pipes under the sink for signs of freezing, such as frost or condensation. You can also try using a hairdryer or hot water to thaw out the pipes. If the problem persists, it's best to call a professional plumber to assess and fix the issue.5. Check for frozen pipes

If the water pressure in your kitchen sink is low, it could be affecting the flow of cold water. You can check the water pressure by attaching a pressure gauge to an outdoor faucet or the laundry room faucet. If the pressure is below 40 psi, it may be causing issues with the cold water flow. You can adjust the pressure by adjusting the water pressure regulator or calling a plumber to do so for you.6. Check the water pressure

A clogged pipe can also be to blame for no cold water in the kitchen sink. If you have recently had any plumbing work done, debris or sediment may have gotten stuck in the pipes.

If your kitchen sink has separate handles for hot and cold water, the issue may be with the faucet cartridge. This is the mechanism inside the faucet that controls the flow and temperature of the water. Over time, it can become worn out or damaged, leading to issues with the cold water flow. You can try replacing the cartridge yourself or call a plumber for assistance.8. Check the faucet cartridge
