When will I get a sewer inspection final report?

There are a few things you need to keep in mind when reinstalling the power cord on your Cobra LX500 sewer machine. First, make sure that the cord is unplugged from the power source before beginning any work. Next, locate the two screws that hold the power cord cover in place and remove them. With the cover removed, you should see the power cord attachment point. Firmly gripping the cord, insert it into the attachment point and tighten the screw to secure it. Finally, replace the cover and screw it back into place. With that done, your power cord should be properly installed and ready for use.

having gone through this !
Would suggest getting plumber to run a wire coil spinning unblocker down sewer line
if you want peace of mind then get a camera inspection after this unblocking..

I had my sewer pipes block twice

My camera inspection revealed my sewer pipes had moved (plastic pvc in clay ) and pulled out of junctions in two locations. This caused the sewer to block up again and a tree root was in one if the broken joints.

There may be a venting problem with the sewer lines. These machines expel water very fast and at higher pressures than other types of machines. This can cause suctioning of water from drain traps if there is improper or clogged venting of the sewer lines. Have the sewer lines checked by someone knowledgeable about proper venting practices.

Ensure all your additional rough in plumbing is capped, and toilets or sinks that are not used for long periods of time , sometimes p traps may dry up allowing sewer gasses to enter the home so use them once in a while or fill with water once in a while ,same with floor drains. If that isn't it check that you have them installed.

Sewer lines can be 3 feet deep to 25-50 feet deep depending on location.

Residential sewer lines are generally 3-5 feet on flat yard depending on local code.
Deeper lines if house is on hill etc.
Local permit board might have drawings and general elevation.
Locate manhole near house to determine which direction main sewer line runs. Main sewer line will be 20 or more feet deep. However homes do not connect at that depth. Homes connect at shallower depth on a branch pipe, and then branch drains into the main sewer line.

Your sewer drain may be backing up.

Watch your drain line in the wall when the final pump out begins.

Start a cycle. After the fill, advance to final spin and watch drain in the wall.
