We can't even imagine how many things can cause blockages and clogging in the sewer, which in some cases can cause a much bigger problem than a simple blockage.
It happens that due to the blockage, the sewer pipe cannot withstand the pressure that only increases from the sewage rushing through it, so it can slip apart at the joint, flooding everything.
In our videos below you can see how large an area it can flood, which can be quite annoying. Therefore, it is worth thinking about sewer maintenance annually and, if necessary, channel cameraing or cleaning. This way, you can prevent bigger problems, not to mention the risk of infection, which is easier on your wallet and can also avoid annoyance.
