Where is this pipe blocked!
While doing laundry the other night when the washer started to empty into it's drain pipe it started to overflow. Then I noticed that the bathroom toilet-which is also in the laundry room was also filling with water. I next found that taking a shower upstairs caused the downstairs toilet to back up. This was just soapy water. The upstairs toilet is working. The kitchen drain also seems to connect with the laundry drain pipe to the big pipe in the basement. Where is it blocked?
It is a 10 yr old septic system. I do have a lot of animal hair in my house with 6 dogs but I always have the washer hose covered with a lint/hair guard
Thanks
