Do I need a plumber?

[Matt Rasich]

I was hoping to fix this issue myself but I don't know where to start. Pictured is my basement drain overflowing with water - it only happens when the washer machine is draining into the sink. I have no problem when I run the water in the sink by itself. I've owned my place and washer (new) for about a year and a half without an issue. I have no idea what the solution is. Any help would be appreciated.

Matt the pipe is draining with the faucet but with the increase of water flow from the washer it overflows. I would guess that there is a small clog after your floor drain that builds up with the amount of water from the washing machine. Try removing the grate snake the pipe with a small cheap snake tool from Home Depot. You might be able to tell where the clog might be from the floor drain by timing the water when it drains and/or listening to the water at the floor drain for the change in the sound of the water once it starts to back flow. Hopefully this helps.
