It's not draining at all and I have a nice broken blister on the palm of my plunging hand.
All kinds of nasty stuff is coming back up, we're no longer headed to dinner and it's a disaster.
Emergency plumber called, sketchy guy calls back. I tell him he's not coming over. Out of Drano.
Time to try my Shop-Vac, first I jam the hose down the drain and suck the water up. Maybe the suction will pull whatever is in the drain up and out. No dice - still not draining.
Next it's reverse the hose and take a wet wash cloth to wrap the hose end and try to blow the clog down. That does the trick. It's draining like never before.
