If you've turned on your bathroom sink and only hot water is coming out, you may be experiencing a common plumbing issue – no cold water in the bathroom sink. This can be frustrating and inconvenient, especially if you need to wash your hands or face. But don't worry, there are a few potential solutions to this problem.No cold water in bathroom sink
Before you try to fix the issue, it's important to first determine the cause. One possible reason for no cold water in the bathroom sink is a malfunctioning shutoff valve. This valve controls the flow of water to your sink and if it's stuck or damaged, it may not be allowing cold water to come through. To fix this, you can try to turn the valve off and then back on again, or you may need to replace the valve entirely. Another potential cause for no cold water in the bathroom sink is a blockage in the water supply line. This can happen if there is debris or mineral buildup in the pipes. To fix this, you can try to flush out the supply line by turning off the water supply and then turning it back on. You can also use a plunger to try and dislodge any blockages.How to fix no cold water in bathroom sink
If your bathroom sink is only running hot water, there may be an issue with the mixing valve. This valve controls the temperature of the water coming out of the faucet. If it's not functioning properly, it may be preventing cold water from coming through. You can try to adjust the valve or replace it if necessary. In some cases, the issue may be with the faucet itself. Over time, the internal parts of a faucet can wear out or become damaged, causing issues with water flow. If you suspect this is the problem, you may need to replace the faucet entirely.No cold water in bathroom sink but hot water works

If you're experiencing this issue, it's likely that the problem is with the sink itself rather than the plumbing system. The kitchen sink and bathroom sink may use different supply lines, so if one is blocked or damaged, it may only affect one sink and not the other.
