This is my current situation... My toilet bubbles after about 4 minutes of running the shower and then water begins to backup through the shower drain. If I take off the cap to the main clean-out outside the water will come out of it and not back up to the shower drain or make the toilet bubble. I rented a machine and cleared a blockage in the mainline of about 8 tampons and everything seemed OK... but 2 days later the same backup happened. So, I had a professional come and they said I had a mainline blockage and snaked it at the clean-out at the back of the house up to the front of house which appeared to have cleared an unknown blockage and everything was OK for another 2 days and then the same thing is happening again. I ran a 25 ft snake down the back bathroom vent but didn't run into anything and the backup still exists. Also when the clothes washer drains both of the toilets will bubble and water backs up into both showers and drain very very slowly. My understanding is since a bubbling toilet indicates a blockage or partial blockage in the mainline... does that include branch lines from the toilet/shower? In that case do you suggest pulling up the toilet to snake it?

The professional has only recommended that if the problem persists to camera the line to locate problem.

My house is 9 years old and on sewer.

I hope you can understand what I'm trying to describe and I would greatly appreciate if you would give me some suggestions where to go from here.

Camera the line will definatyly tell you what's going on but it has to be unstopped first or in other words not holding water also you may have a sagin your pipes somewhere hope its not a slab home and that's the case
