We have a clog in our bathroom sink. It will not drain at all. We have snaked the line, ran a garden hose from the house down into the line, flushed with a garden hose and snaked from the roof vent, all to no avail. We have been dealing with this issue for many months. Sometimes it has helped using the garden hose from inside allowing us a few weeks of no problems, this time nothing seems to help. The bathtub gurgles when it is draining and it also makes the toilet gurgle. Any suggestions as to what is going on? Thanks, Bre
