In response to Re: Toilet bubbles when washer drains
: When the washer drains, my toilet bubbles and bubbles loudly then drains. I can hear the kitchen sink and a small amount of water will come up into my tub. About 18 months ago I had the same problem, so I had the main line snaked and blasted with a high pressure truck. What could possibly be causing this. Could it be a main line clog or is it possible for the air vent to be blocked. When they snaked the line all they found was that black gooy sludge.

It appears that the main drain line is partially restricted causing the problem. Why did they need to water jet the line last time? Usually a good cleaning with the right equipment does the job. It may be worth having the line camera inspected if the problem becomes persistent, you can request a tape copy for your records.
Good Luck. e-plumber
