This weekend our toilet stopped working, sure, a problem everyone has. Except my issue isn't duckbills, isn't the bellows, and not the pressure switch. it will build vacuum fine and turn off once vacuum is reached. The problem is the line between the toilet and the vacuum reservoir tank. If I pull the hose out of the vacuum reservoir tank you can hear the air rush in and the pump starts running. It will continue to run until I put the hose back in this creating a seal and then it stops about 30 seconds later. I have pulled the toilet out so I can snake straight into the hose, but I cannot get the hand snake more than 3 feet in before it hits either the clog (Which it feels like) or a bend in the hose that it can't get past. Any ideas before I call a plumber? I have also tried using a plunger, and have actually worn a pretty good blister into my right hand by working the plunger to no avail.
