washer/garbage disposal drain

have drain of some sort in the floor of the laundry room where garbage disposal/washer both empty. heard tremendous noise and rushing water. water coming out of the drain which resembles (somewhat) a sump pump. Turned off water valve in ceiling which allowed water to subside. I have no idea what this is or what to do. appreciate any insight.

Weird. A garbage disposal dumping to a floor drain???? Is this a restaurant?? Was the rushing water hot?? When you turned off that valve to stop the water, what else in now not working? How about some pictures??

If you can post a picture to help us see what you have. It wil help a whole lot.

Whatever you have, it is unorthodox and most likely very "uncode". I don't think this is a DIY project. It sounds like a classic case of a hack job and a good example of why inspections are important. You need a professional plumber on site to evaluation what you have and advise you on what will make it right.

It could be a grease interceptor, in which case it could be full of whatever you ground up in the disposer over the past few years. We would need a picture to even make a guess as to the problem.
