I recently noticed a sewer smell in my drain crock in the basement, also there is some kind of heavy growing fungus like stuff on walls of crock, my washer drains into this and I
Use bleach in my wash and that hasn't killed it, It looks like I have a fungus type thing going on what should I do? I also notice the smell around the side of my house outside closest to the crock inside. Some one said to clean crock and stone out then pour in bleach really don't know what to do any advice would be appreciated. Thanks

Bleach loves nasty stinky stuff. The person who told you that may be right. Or, just dump bleach directly down the drain and see if that does it.
