2nd floor laundry question floor drain

Laundry is on my 2nd floor. Is it allowed / "code" to install a floor drain into the same pipe that the laundry uses? I was thinking of cutting the floor and installing a Y into the drain pipe and a P trap to the drain.

Welcome to the forums! Does the picture depict the second floor set up or an abandoned first floor piping? You will need a trap if it is installed below this.

Even if it complies with code, there is no way that it can handle that much water, if the machine is draining & there is a flood at the same time. It's a false sense of security.

Agree with Pulpo, it just seems like a bad idea, to code or not. If that line clogs, the floor drain won't be able to drain the resulting overflow. Granted, you can always find a place where a clog will block both lines, but I'd want that point to be in a 3 or 4 inch line, not a 2 inch line.

Thanks everyone. I just removed the laundry machine from that spot in the image. It doesn't look like it has moved for over 10 years. I'm re-doing the floor and was thinking about installing a drain. I will pass on it.

What about an automatic shutoff valve with water sensor? Good idea or waste of $250?

Pretty cheap insurance for a second floor laundry, given cost of repairs after a flood. Or you can be diligent about replacing the hoses every couple of years and diligent about turning off the water when the washer isn't in use. Putting in a single handle laundry shut-off makes it quick and easy to turn the water off. Those two things will buy you a lot of safety margin.....

A high water alarm might be a good idea.
