Why Does My Toilet Keep Overflowing?

By September 15, 2017September 28th, 2022No Comments

An overflowing toilet can be one of the messiest cleanups you ever face. Thankfully, you can easily be taught about proper toilet maintenance and common problems associated with your plumbing systems. If you experience a full-blown overflow, immediately turn the water valve off behind the toilet. Remember to get towels and clean up the water immediately, as the water could cause damage to the floor, walls, and paint around it. Here are some common causes of toilet overflow and how you can prevent and combat them.


A clogged toilet could be one of the most common reasons your toilet overflows. In most cases, you will be able to see the blockage at the bottom of your toilet. If you notice a blockage, do not flush the toilet, as the water level may surpass the brim of the toilet. To clear the drain, use a plunger until the drain is visibly clear.


Leaks can occur not only in toilets but also in sinks and bathtubs. If you notice a toilet leak, you should shut the water off and call a plumber before the water level rises. Even if the leak isn’t causing the water level to rise, the leak will raise the cost of your water bill. In case of a leak, you should always seek professional help before the leak worsens and overflows your toilet.


Sometimes your toilet may not be draining, and there could be no obvious or apparent reason for it. If you do not notice any blockage in the toilet bowl, then more than likely there is a blockage beyond the bowl and in the pipes. If the water level rises without being flushed down, never flush again until you are sure the blockage is gone. To clear a blockage you can’t see, try using a plunger. If you clear the blockage, then the water level will drop to normal. If not, call a professional to get your toilet snaked and working properly.


Toilet overflows can be highly harmful to the floor, paint, and surrounding walls. Not only that but bacteria and germs from your toilet bowl and water can be spread to other surfaces in the event of an overflow. Follow the guideline from this blog, and if the issue doesn’t subside, contact a professional to handle the remaining labor.
