My washing machine is on the second floor. Last weekend my washing machine was off balance and as a result of that the hose from the washing machine came off the pipe that was in the wall. i didnt know i was supposed to have a trap adaptor between the hose and pipe. So water came from the hose which was separated from the pipe. I have a floor drain in there, but the water made it's way down to the first floor, underneath the laundry room is the kitchen so water was coming down the kitchen ceiling light and ceiling. Also water made its down the basement ceiling only a couple spots leaking as a result i think from water being on the kitchen floor and it went through the ceramic tile. I was wondering could there be any serious damage done, and is there supposed to some water in the floor drain. And i have not turned the light on since this happened and have taken the bulbs out.
