I've attached a picture, we installed the new sink as part of a kitchen reno, new cupboards mostly. It drained fine but occasionally when i ran the garburator water and bits of food would blow up the second sink.
last night the sinks stopped draining altogether, i pulled off the whole bottom part from the garuburator, sink and cross pipe at the flexible connector and nothing was plugged, i blew into the cross pipe and it didn't seem blocked.
Any thoughts on what this could be? I'm assuming that the water is not draining into the stack which is about 9 inches to the right of was you can see in this picture. this is the only thing that goes into the stack so i can test it at another sink etc...
