Moni,
Wow, your house sounds gorgeous. Have any pictures?
Plumbing and electrical (be careful)? Now I am overwhelmed with awe.
Speaking of plumbing and electrical, somewhere in the middle of our kitchen remodel I installed the sink, plumbed it, installed the garbage disposal, and hard wired and plumbed in the dishwasher. When I finished everything looked great! I even used chrome plumbing for asthetics.
However, there was one minor issue; the garbage disposal was attached to one side of the sink with an drain pipe T-ing into the drain pipe coming from the other side of the sink. The T fitting that joined the two had a slight downward curvature (a slight baffle) in the middle to encourage all drain water downward into the gooseneck.
Oh, did I mention that our new garbage disposal is 3/4 hp (not a great amount of power but enough to suck water through it and into the drain pipe at a high rate of speed.
Furthermore, at that time we were having sink exhaust issues, causing our sink to back up to the point of having a couple inches of standing water in the basin.
Another important point to note, is that the disposal switch is on the opposite side of the sink from the disposal itself.
Well after I finished the job, I ran a little water into the disposal flipped the switch and....everything worked like a charm. I check every fitting and could find no leaks. At this point I was very happy with my work.
About thirty minutes later, after my wife had been using the sink for a while, she advised me that the disposal side was backing up. I told her, this was not a problem, I was aware of it, and would have it fixed shortly. I also mentioned, that if she flipped on the disposal it would force the sink to drain. Armed with this information and having no reason to distrust my advice (at least up until this point) she leaned across the side of the sink opposite the disposal and flipped the switch. Just as I had said, the disposal drained the sink. However, since the T fitting had only a slight baffle the water was not encouraged in the least to go down into the gooseneck but instead proceeded across into the other drain pipe and up out of the opposite side of the sink. Yeah, that would be the side of the sink my wife was leaning across. More specifically her face was directly above the drain.

FYI, 3/4 hp can shoot water up out of a drain at a decent velocity. Good thing she has a sense of humor.
Within a week I had replace the T fitting and everything works perfectly now.
BTW, that's a good looking pup!
