Got this high efficiency washer last year and it was hooked up when delivered.

Had painters come and they unhooked it. They hooked it back up and it is leaking now. I am confused about how to install it properly, but something isn't right.

The cold water opening on the washer has a y-splitter that was added when it was originally installed. Do I hook both hoses to that like it is in the picture? And connect nothing to hot? If I connect 1 to hot and 1 to the splitter on cold then obviously water is flowing out of the end of the y-splitter that has nothing connected. Are we missing a piece? Maybe the painters threw it out, who knows.

All I know is I did a load of wash and there was a bit of water on the floor. Never had that problem before until it was unhooked then hooked back up by these people.

Cant add my pics for some reason.

Thanks for any advice.
