I have one of those sinks in my bathroom that are basically a glass bowl that sits on a platform with the cabinet and plumbing underneath,vessel sink I think it is called..I installed it myself and all seems fine except when the the sink is filled with water and then drained the water seems to empty out at a very slow rate...annoyingly slow.Its quite possible that I could have the plumbing wrong as I am no plumber but just wondering if anyone else has this problem?
