ANOTHER slow draining vessel sink(s)
I recently had 3 stone vessel sinks installed with grid drains. All three drain slowly while the faucet is running. As soon as I turn OFF the faucet or set it at little more than a trickle, the sink drains quickly. Bubbles seem to collect in the drain while the water is running causing the slow draining. I previously had no problem in any of these bathrooms with the former set-in sinks that had overflows. I am considering purchasing 3 flip top drains to replace the grids as there is more of an opening and, I am hoping, less of a chance for the air to get trapped. Any comments? Help! I have three beautiful nonfunctioning sinks!
