How are sewer and drain inspections addressing issues before they become a problem? The truth is, these types of inspections alert people to problems before they become a major catastrophe. There are a couple of reasons that more minor problems are currently being found. The biggest reason is because of the advances in equipment and technology, thereby allowing professionals to do these types of inspections when it simply wasn’t possible several years ago. Therefore, more inspections are being done every single year. Because of the increased number of inspections, more people are finding problems that could be potentially serious, usually before they ever get to that point.
