I have been wondering about that, I have two Ticor zero radius sinks and they drain perfectly so the complaints about them not draining have been rather perplexing.

I suspect that if it is an installation problem, it is related to the way that it is mounted into the countertop which would probably be a pain to redo once it was caulked.

And since the plumbing isn't usually hooked up until after the sink is caulked, maybe insisting on checking it with a level?

Our fabricators took the sinks to their shop to do the cut outs, but installed them on site after the counters were placed, maybe you (or your GC) could ask them to double check at that point?

Thanks Hollishenry! I will mention it to my GC.
