In response to Re: Indirect draining a washing machine
: My washing machine and laundry tub currently empty into a floor drain in the basement. Since the floor drain is trapped, and connected to the house sewer, everything ends up where it is supposed to.

: My question is, is this okay or do I need to run a new drain line over to my main stack? If it is okay, what is the proper way to do an indirect drain? The current setup has a pipe sticking down the throat of the floor drain, but something tells me that ain't right...

: We don't do inspections around here, so I'm just looking for a safe and effective way to do this, preferably a code-approved way, just on general principles.

The proper installation according to code would be for the laundry tub and WM to connect properly to the sanitary drainage and vent system with the appropriately sized lines.
In theory, a hook up as yours would work if the floor drain was 3" and vented, and had a strainer cover with a funnel attached to prevent splashing, similar to an indirect drain connection in a restaurant.
Good Luck. e-plumber
