An old and not regularly maintained sewer can cause major problems, and unfortunately quite common. We often only notice the problem long after the problem has occurred, and by then it can cause great damage.
You can also see it in our video below, that in an old basement, a poorly assembled sewer broke off after it became clogged and could no longer withstand the load. In this way, it is not only a question of blocking, but also channel also about replacing a piece of it.
That is why we recommend regular sewer maintenance to everyone. Replacement of old pipes, and a general channel survey, to prevent similar problems by locating and cleaning possible blockages.
