One of the most frustrating problems to encounter in a bathroom is when there is no hot or cold water coming out of the sink faucet. This can be a major inconvenience, especially when trying to wash your hands or brush your teeth. But don't worry, there are some simple steps you can take to troubleshoot and fix this issue.No hot or cold water to bathroom sink
If you find yourself in a situation where there is no hot or cold water coming out of your bathroom sink, the first thing you should do is check the shut-off valves under the sink. Make sure they are fully open and not partially closed, as this could be the reason for the lack of water flow. If the valves are open and the water is still not flowing, there may be a larger issue at hand.How to fix no hot or cold water to bathroom sink
If the shut-off valves are not the problem, the next step is to check the aerator on the faucet. Over time, mineral deposits and debris can build up and clog the aerator, causing a decrease in water flow. Remove the aerator and clean it thoroughly with a mixture of vinegar and water. This should help improve the water flow from the faucet.Troubleshooting no hot or cold water to bathroom sink
If there is no water coming out of your bathroom sink at all, there may be an issue with the water supply line. Check to make sure the supply line is not kinked or twisted, as this can restrict water flow. If the supply line appears to be in good condition, there may be a blockage in the pipes that will require the assistance of a plumber to fix.No water coming out of bathroom sink
In some cases, the problem may lie within the faucet itself. If you have a single-handle faucet, the cartridge inside may be worn out or damaged. This can cause a decrease in water flow or no water at all. You may need to replace the cartridge to get your faucet working properly again.Bathroom sink faucet not working

This can be caused by a variety of factors such as clogged pipes, a faulty pressure regulator, or a problem with the water main.
