If you've noticed a decrease in water pressure in your bathroom sink, the first place to check is the aerator. This small mesh screen at the end of your faucet can become clogged with mineral deposits, debris, or even rust. These blockages can restrict the flow of water, resulting in low water pressure. To fix this issue, simply unscrew the aerator and clean it thoroughly with a mixture of water and vinegar. This will help dissolve any buildup and restore your water pressure.Clogged aerator in bathroom sink | Low water pressure in bathroom sink | Troubleshooting low water pressure

If the buildup is severe, you may need to replace the faucet altogether.Mineral buildup in bathroom sink faucet | Low water pressure in sink | How to fix low water pressure
