|In response to Re: Kitchen sink back-up|
: 35 year old building. The scenario is this: One apartment on top, one on the ground floor. Kitchens are exactly on top of each other, but no other apartments are connected to them. (Pipes, that is)
: When the top unit empties their sink, it gurgles loudly downstairs, and sometimes sewer smells are released.
: Yet when the lower unit sinks are emptied, the water flows freely.
: The line was augered from the bottom sink to the main sewer line. They also did a pressure jet on the same line. No blockage was found, but no changes to the gurgling.
: I then insisted that they auger through the vent from the roof down. They did, but not all the way to the main sewer line (there is nothing blocking it anyway). No blockage was found, but no changes to the gurgling either.
: It is costing me not only money, but time and inconvenience to my tenants.
The vent for the downstairs kit sink is plugged. The vent for the upstairs will not allow the snake to get the the vent for the downstairs even though they are connected together in the wall. You will have to open the wall in the downstairs kit and find the vent tee and clean it from that point.
