What to Do When the Toilet Won’t Stop Overflowing

We’ve all experienced it – the dreaded overflowing toilet. It’s a frustrating situation that can quickly turn into a nightmare if not handled correctly. Thankfully, it’s not the end of the world if you know what to do. In this article, we’ll go through the steps you can take to stop an overflowing toilet and avoid any major damage to your bathroom.

Step 1: Shut off the Water Supply

The first thing you should do when you notice the toilet overflowing is to stop the flow of water. Locate the water supply valve behind the toilet near the floor, and turn it clockwise until it’s fully closed. This will stop the flow of water to the toilet and prevent it from overflowing further.

Step 2: Don’t Flush the Toilet

It’s a common reaction to want to try and use the flush handle again, but this will only make the situation worse. Flushing it again will cause more water to fill the bowl, which will overflow even more. Patience is key in this situation.

Step 3: Try Plunging

A plunger is usually the first line of defense when dealing with a clogged toilet. To use a plunger, place it firmly over the toilet’s drain, making sure it forms a good seal. Plunge up and down to create suction and pressure, which can dislodge the blockage and allow water to flow freely again.

Step 4: Call a Professional

If the above steps don’t work, or you can’t locate the source of the blockage, it’s time to call in a professional plumber. They have the experience, tools and knowledge to get the job done quickly and efficiently.

Step 5: Avoid Future Clogs

To prevent future clogs, avoid flushing anything other than toilet paper and human waste down the toilet. Items like paper towels, feminine hygiene products, and baby wipes can cause blockages and create major issues. Additionally, regular maintenance like cleaning the toilet and checking the plumbing can help keep minor issues from turning into major ones.


Dealing with an overflowing toilet can be a stressful situation, but it doesn’t have to be a disaster. If you follow these steps, you can stop the overflow and prevent further damage to your bathroom. Remember to shut off the water supply, don’t flush, try plunging, call a professional if needed, and take steps to prevent future clogs. With these tips, you can handle the situation like a pro.
