I have a 2 story house. Just today the drain in the laundry room started over flowing. It doesn't look like I have a sump pump. I tried using drain o and enzyme cleaner in it but it still is draining really slow and overflowing if I run the washer or dish washer. It hasn't been raining here so I don't think its that. Any advice i was planning on getting a snake and snaking it tomorrow any other sugestions?
