Bad smell from drain
Hi guys. We are having an issue with the drain at least I hope that is the problem. Our washer sits in the lower bathroom and had a typical wall drain. There has been such a bad smell coming from that bathroom that it is effecting the entire lower level of the house. While doing some spring cleaning, I pulled the plastic drain hose out of the wall to find it was covered in gunk. It smelled really bad. I did my best to clean off the hose inside and out, and the pipe as well. Now the smell has returned with a vengeance. Is there anything I can do to remove this smell? Is there a better way to clean out the pipe? Or do I just have to be vigilant and make cleaning out this drain part of a monthly routine?
