If you turn on your kitchen sink faucet and no water comes out, the first thing you should do is check the water supply valve. This valve controls the flow of water to your faucet and can become stuck or damaged over time. To check the valve, locate the shut-off valve under your sink and make sure it is fully open. If it is closed, turn it counterclockwise to open it. If it is already open, try turning it off and on a few times to loosen any debris that may be blocking the flow of water.1.

Possible Causes of No Water Coming Out of Kitchen Sink Faucet
1. Clogged Faucet Aerator
One of the most common reasons for no water coming out of a kitchen sink faucet is a clogged aerator. The aerator is a small mesh screen located at the end of the faucet spout that helps to regulate the flow of water and prevent splashing. Over time, it can become clogged with mineral deposits, debris or sediment, restricting the water flow. This can happen more frequently in areas with hard water. To fix this issue, unscrew the aerator from the faucet and clean it thoroughly with vinegar or a descaling solution to remove any buildup.
2. Damaged or Clogged Water Supply Lines
Another possible reason for no water coming out of a kitchen sink faucet is a damaged or clogged water supply line. These lines are responsible for delivering water from the main water supply to your faucet. Over time, they can become clogged with debris, causing a decrease in water pressure or a complete blockage. In some cases, the supply lines may also become damaged due to wear and tear, resulting in leaks or a complete loss of water flow. If this is the case, it is best to call a professional plumber to replace the damaged lines.
3. Faulty Faucet Cartridge
A faulty faucet cartridge can also be the culprit behind no water coming out of your kitchen sink faucet. The cartridge is a valve inside the faucet that controls the flow and temperature of the water. If it becomes damaged or worn out, it can cause a decrease or complete stop in water flow. This is a more complex issue and may require the expertise of a professional plumber to replace the faulty cartridge.
4. Frozen Pipes
If you live in an area with cold winters, frozen pipes can also be a possible cause of no water coming out of your kitchen sink faucet. When the temperature drops below freezing, the water inside the pipes can freeze, causing them to expand and potentially burst. This can lead to a complete loss of water flow. If you suspect frozen pipes, it is important to thaw them out as soon as possible to prevent further damage.
In conclusion, there can be several reasons for no water coming out of a kitchen sink faucet. It is important to troubleshoot and identify the root cause in order to fix the issue and restore water flow. If the problem persists, it is best to consult a professional plumber for further assistance. Regular maintenance and cleaning of your faucet can also help prevent these issues from occurring in the future.
