2 story house-built 1995-on occasion the washer machine drain (2nd floor) overflows the downstairs toilet. If I look at the clean out in the yard there is standing water in the waste drain pipe. Plunging it clears the water. I had the line boroscoped and it is clear form the clean out to the main. The plumber said it was an issue with the way the waste lines from the downstairs bathroom are tied into the main drain line. Instead of ripping up the floor and redoing the drains is there a way to put an auto vent on the clean out connection in the yard? Any other suggestions? Could a partially blocked stack vent cause this? It doesn't happen all the time but 2 floods downstairs is enough.

It could be a number of things causing this to happen and without seeing how things are piped it would just all be guessing. Adding a vent onto the cleanout outside would do nothing nor is it something you would want to do.
if the drain in your yard is holding water I would run a snake from there to the street.....I would start there
