Here is a rough drawing:
I have a kitchen sink that is not draining and it is doing it chronically. I also have excessive moisture in the basement near the kitchen drain outlet in the concrete foundation. I cannot dig to see drain line outside because a large cement patio is above it (which is probably crushing it). I can dig between the porch and the closest toilet stack to cap it off once I join them, but my question is, even though there is enough slope to get the kitchen drain water to the stack are there any downsides do doing this I have not thought of?
Also, the vent stack for the kitchen is clogged as well. I would just put a hose down it but this old house has the cast iron vent connected to the kitchen sink PVC with a rubber boot with clamps, and this coupler is 5 inches (literally) above the breaker box and generator transfer switch.... I am sure that the water flushing down the stack would blow this rubber coupler off because, well, everything that can go wrong in this house has. The sink is right above the electrical box too and when I plunged the sink drain the compression fitting blew right off and a whole sink full of water leaked down JUST to the right of the electrical box thanks to the slant of the floor haha.
Thanks for taking the time to read and I hope my idea is possible.

Well, the first thing is that plunging a drain line should NEVER "break" a connection of any kind. Your description does not convince me that your diagnosis is correct as to what the REAL problem is.

The compression fitting that came off was the one below the sink drain before the Y (two sink basins in sink). It blew off because the plumber never put a slip ring on the pipe before screwing down the fitting.

Just to update my own thread incase anyone comes along having the same issues:
I cleared the vent line with a garden hose and a drill powered pipe snake. The rubber boot did come loose as I predicted but I put a larger slit pipe around it before clearing the vent and saved my electrical box. The water flowed just inches to the right of it. Drain is still clogged :|
