This can be frustrating and inconvenient, but luckily, it is a problem that can be easily fixed. In this article, we will guide you through the steps to take to get your toilet flushing properly again. Let's get started!How to Fix a Toilet That Won't Flush | MAIN_bathroom sink water drains to toilet tank
The first step to fixing your toilet is to identify the problem. In this case, the issue is that the water from your bathroom sink is draining into the toilet tank, causing it to overflow and not flush properly. This can happen due to a faulty fill valve or a clogged drain. Take a look at your toilet and see if you notice any water coming from the sink drain into the tank. If so, you have identified the problem and can move on to the next step.1. Identify the Problem
Before you start working on your toilet, it is important to turn off the water supply to avoid any potential mess. Locate the shut-off valve behind the toilet and turn it clockwise to shut off the water. Then, flush the toilet to empty the tank and make sure there is no more water flowing into it.2. Shut Off the Water Supply
The next step is to clear the drain between your sink and toilet. Use a plunger or a plumbing snake to remove any clogs that may be causing the water to back up into the tank. Make sure to wear gloves and take any necessary precautions to protect yourself from any potential mess or bacteria.3. Clear the Drain
If the drain was not the issue, then the problem may be with the fill valve. The fill valve is responsible for refilling the tank after each flush. If it is not functioning properly, it can cause water to back up from the sink drain. To check the fill valve, remove the tank lid and flush the toilet. If the water level rises rapidly, then the fill valve may need to be replaced.4. Check the Fill Valve
To replace the fill valve, start by turning off the water supply and flushing the toilet to empty the tank. Then, unscrew the water supply line from the bottom of the tank and remove the old fill valve. Install the new fill valve according to the manufacturer's instructions and reattach the water supply line. Turn the water supply back on and test the toilet to make sure it is flushing properly.5. Replace the Fill Valve
If you are not comfortable or experienced with plumbing tasks, it is always best to call a professional to handle the issue. They will be able to diagnose the problem and fix it efficiently and effectively, saving you time and potential frustration.6. Call a Professional
To avoid this issue from happening in the future, make sure to regularly clean your sink drain and avoid flushing any large items or debris down the toilet. You can also install a backflow prevention device to prevent water from backing up into the toilet tank.7. Prevent Future Issues
