My kitchen sink has a good size drain pipe heading into the basement and out:
And what I assume is a pretty normal connection from the drain to the sink:
But when you look at the drain in the sink, the way it's all put together, the actual holes through which water can drain are quite limited:
I can't help but think that if this were set up better, the sink would drain faster and possibly get clogged less often. Is there a different tailpiece or other part that I can get that has a wider diameter? Or are these so standardized that what I've got is all I can get?
I realize my original post didn't really capture my question accurately. So yes, I always have a strainer:
and my question is not about the crossbars in the standard strainer (I've labeled "YES" in the image below), but rather the piping that lies right beneath the strainer and seems to impinge on the drain (labeled "NO" in this image):
The black "stack" is a 2" pipe at floor level, but it shrinks as it goes up. The white pipe that branches off to the sink is 1 1/2" as suspected:
