A gradual reduction in water flow in your kitchen sink can be caused by various factors. Here are some common reasons and steps to help you diagnose and potentially fix the issue:
Clogged aerator: The aerator is a small mesh screen located at the end of the faucet spout. Over time, sediment and debris can accumulate on the aerator, reducing water flow. To fix this, unscrew the aerator from the faucet using pliers, clean it by soaking it in vinegar or descaling solution, and then rinse it thoroughly before reattaching it.
Blocked or damaged water supply line: Check the water supply lines under the sink for any kinks, bends, or visible blockages. If you find any damage, replace the supply line. Sometimes, debris can also accumulate in the supply lines, so it's a good idea to disconnect them and flush them out.
Clogged pipes: The main drainpipes or the ones leading to the sink may be clogged with grease, food particles, or other debris. To address this issue, you can try using a plunger or a drain snake to clear the clog. If the clog is more severe, you may need to call a plumber for professional assistance.
Low water pressure: Check if the low water pressure issue is specific to your kitchen sink or if it's affecting other faucets in your home as well. If it's only the kitchen sink, then the problem is likely localized to that area and not a general water pressure issue. In this case, the other points mentioned above may help resolve the problem.
Water supply issues: Sometimes, water suppliers may conduct maintenance or experience issues with their infrastructure, leading to temporary low water pressure. Check with your neighbors to see if they are also experiencing similar problems. If it's a widespread issue, contact your water supplier for more information.
Faucet cartridge or valve problems: The faucet's internal components, such as the cartridge or valve, may become worn out over time, affecting water flow. This usually requires the replacement of the faulty parts, which might need a professional plumber's expertise.
Remember to turn off the water supply before attempting any DIY fixes, and if you're uncertain about the cause of the problem or how to fix it, it's best to consult a licensed plumber who can accurately diagnose and resolve the issue.
