Gravel in sewer drain

[Cainsey]

The sewage drain in my house got clogged and my entire bathroom floor got flooded. I got a plumber to come and use a power auger to release it. The next day I sent a camera down there and discovered gravel in the pipe about 20-30 feet out. This house is 40-50 years old and I've been the new owner for roughly 6 months. I did not see any cracks in the pipe but may have been covered by debris. How is it possible for gravel to get in the drain?

I will accept you to viewing it asap.

Most likely the bottom the pipe is rotted out. Hard to tell from the video. Hire out a better camera.

Canadian sewers might be deep.

Clogged pipes can also occur as a result of biofilm formation and slow pipe velocities. I believe this is a result of a mix of factors.
Drain the system and install a service inlet, which can be a threaded endcap or a tee with a standpipe that is higher than the system's maximum water level. You could then insert a pressurized hose and clean the pipes as needed. I had a similar issue that was resolved by a plumber a few years ago. While you're at it, give the piping a thorough cleaning.
