房检建议做camera inspection of main sewer line to street，该不该做？

坐标南加，刚买一房，房检报告有这么一段：

"The inspector observed the presence of a large shallow rooted tree in the front yard area. As such, a camera inspection of the main sewer line to street may be warranted."

打听了一下要300+，不知道值不值得花钱做？假如不做会有什么严重的后果吗？还是不做等有问题再说？谢谢各位老大
