Toilet gurgles and then backs up
Recently our toilet started to occasionally gurgle and when we try to flush it afterwards, it backs up and will not flush properly. Sometimes it will flush fine for a couple of days, then it will gurgle a couple of days in a row and then it won't flush right. The problem seems to be worse in the afternoon. Also, we are connected to a public sewer system. Don't know if that could have any affect or not. We have plunged and snaked the toilet and still have this problem. Any ideas?
