A shut off valve is an important component of any plumbing system, and it is especially crucial in the bathroom. It allows you to turn off the water supply to your sink, toilet, or shower in case of a leak or repair. However, if you find that the shut off valve under your bathroom sink is not working, it can be a cause for concern. Not being able to turn off the water can lead to a flood or water damage, so it's important to address this issue as soon as possible. The most common reason for a shut off valve not working is that it is stuck or seized up. Over time, mineral buildup and debris can cause the valve to become difficult to turn. This can happen especially in older homes with outdated plumbing systems. Fortunately, there are steps you can take to fix a stuck water valve under your bathroom sink. First, try gently turning the valve back and forth to loosen it. You can also try using a pair of pliers to grip the valve and turn it. If this doesn't work, you may need to lubricate the valve with some WD-40 or a similar lubricant. Apply the lubricant to the valve and let it sit for a few minutes before trying to turn it again. If the valve is still stuck, you may need to replace it. This is a more complicated process and may require the help of a professional plumber. However, it is important to address a malfunctioning shut off valve as soon as possible to prevent any further damage. 1. Shut off valve not working under bathroom sink
