In keeping up with all the modern amenities for your home, a concealed cistern has become a popular choice. This type of modern toilet uses the wall or the ceiling behind the toilet seat to conceal the cistern, as the name implies. Usually, there is a dummy tile or wall to access to your concealed cistern. You just have to ask your installer where to locate this prior to installment. However, prior to calling a professional or to knowing if the concealed cistern is, in fact, the issue, you may check if an overflowing problem is simply due to a clog. And if it is, here are tips to stop that.

Step 1 – Observe the Water Level

Observe water level as soon as your toilet bowl starts overflowing for about a minute or two to see if water goes down by itself. If not, it's time to take affirmative action.

Step 2 – Clear the Clog

Use the plunger and try to clear a possible clog. A toilet plunger differs from a drain plunger. Make sure you use a toilet plunger for this problem. It has a cone-shaped rubber bottom. This cone-shaped piece fits almost perfectly into the drain hole. When you push the plunger down, it forces air into the drain hole and into the pipe. Push the handle down in short, quick movements. Repeat this action five or six times. Then, remove the plunger and check the water level of the bowl. If you see it lowering, then use the plunger again until the clog is clears up and the toilet is properly flushing again. If water does not go down, move on to step 3.

Step 3 – Fill the Bucket with Water

Fill a bucket with tap water. Pour the water as quickly as you can into the toilet bowl. Filling the toilet bowl slowly will cause it to overflow again. Pouring the water into the bowl will help create suction in the drainpipe. Repeat this process two or three times. If plunging your toilet and flushing it with water does not clear the clog, you'll need to try yet another remedy. The clog in your toilet is not a simple one, so it needs more force applied to it.

Step 4 – Unroll the Wire

Take your toilet snake and unroll a length of wire. Place the end in your toilet bowl and guide it into the drain hole. You will need to push the wire down by holding onto the housing and wiggling it back and forth into the drainpipe below your toilet. Once the water starts to leave the bowl, you'll know you have reached the clog. Flush the toilet two to three times to make sure it's working properly again. Then, carefully remove the snake and wind it back up.
