Hi,

I have a copper sink in the bathroom and because it doesn't have an
overflow, the water drains very slowly. It is not too much of a problem,
because as the sink begins to fill, it drains more quickly due to
gravity, but as it drains down, the rate slows down dramatically.

But my kitchen sink (as most kitchen sinks) also doesn't have an
overflow, but doesn't have the same problem. How come? Is it because
kitchen sinks have a larger drain?

Thanks!

Sam

Where is the vent for this sink? The overflow is not supposed to
serve as a vent. If the vent is too far away you might look at adding
an inside vent. Lowes has them. Is there a cabinet under the sink?
