Have you ever faced overflown toilet at your home? How do you feel? Certainly, disgusting and unpleasant. Yes, having an overflown toilet is not pleasant at all. You might enter your bathroom and see the toilet is overflowing. It is happening, but you just have done nothing. 

The question then knocks in your mind; can toilet overflow without being flushed? So, you might become startled and think about the toilet overflowing for no reason. Not. When it happens, it is certainly for sure that something happened behind the scenes. 

Now, what can you do to overcome the problem? Stop thinking about how it is happening. First, stop the overflowing of wastewater as soon as possible. After halting the overflowing, we will think about the reason behind it. Let’s do it. 

How To Immediately Stop The Overflowing Problem?

What should you do when you see the toilet overflow without being flushed?

Should you think about how that happened, or should you try to stop the overflow immediately?

Yes, you think in the right way. First, you should stop the overflow of the water from your toilet bowl. If I were you, I would also do it. Here are some quick solution tips for preventing the overflow immediately. 

1. Immediately Stop The Water Supply

The very first step is to stop the water supply of your bathroom. At first, you don’t know the cause behind the overflow. But it is too much disgusting and horrible to see coming to the wastewater from your toilet bowl and filling the bathroom floor. 

Just shut off the supply line where the water comes from to your toilet. You will find a shut-off valve under your toilet flush tank. If you do not find the valve, stop the main supply line. If the overflow occurs from the supply line, it should be stopped by this time. 

However, if your toilet overflows after shutting off the water supply line, you must be sure that the issue is elsewhere. It might be in your main sewage line or drain.

2. Use A Plunger

While you are in such a situation, you may try a plunger to get rid of the problem. When you use a more excellent plunger, it may have a more extraordinary suction ability. You will also get the extended tapered center. 

Insert the plunger mouth inside the toilet bowl and use the sucking tool to suck the clogged clog tightly and adequately from the pipeline. It is essential to stop the water supply line, and you have already done it. 

You might have to do this multiple times, depending on the clog type. Wait and see that the water starts to run back to the drain. 

3. Try Using A Toilet Drill Or Drain Snake

Even the plunger didn’t work? You failed again, and the situation is getting worst? Don’t be panicked. The problem might be solved differently. Now you must use a drill or drain snake. These two are almost similar. 

Perhaps something significant has been lodged in your toilet’s s-shaped trap. The drill and drain snakes are made for the s-shaped trap of your bathroom. Crank the drill into your drainpipe or insert the drain snake into the s-shape trap. You should now be able to locate the obstruction. Pull them out by using the tools. Alternatively, the drill might break the blockage and allow it to flow down the sewers. 

I hope you got rid of the overflow problem.

Your toilet releases a large number of waters at a time, and it should be appropriately vented along with the wastages. If there is any obstacle in the water flow line, the water could return with more force; with the vacuum the water created. This will make overflow of water.

For how many years have you do not clean your septic tank? If it is more than a seven-year boundary, it is too much possible that your septic tank is fulfilled and unable to store more water.
