Sink will not drain, turn on garbage disposal and it sucks the water down, as soon as I turn off disposal, water comes back up in sink, I have taken off the pipes underneath and they are not clogged, I snaked the pipe going into the wall and it is still doing it, any ideas? When I run the water for a while with garbage disposal on it is fine but as soon as I turn off disposal, water comes back up, the same amount each time?

Sounds like an air pocket - however have you checked the drain outside to see if it is blocked?

No such thing as an air pockey with what you described. You have a clog downstream and the disposal is acting like a pup pushing water up your vent stack. As you turn off the disposal the water standing in the vent comes right back into your sink. How far into the wall did you reach?

We went in about 2 feet... how far should we go in?

Im, no plumber just providing a different view. As for how far... get some plumbing rods and puh them through the drain.
