Water drains slowly out of bathroom sink
About 2 years ago we remodled our bathroom and put in a new countertop with a sink all in one unit.
Than I put a new Kolher Faucet in and ever since the water goes down very slow.
I have talked to Kolher and they told me that it is not the drain on the faucet, the sink.
All other drains work OK.
What can I do to get this problem fixed?
If this is the case why do they make countertops and sinks all in one unit?
Since they told me that it does not have a overflow vent on them.
These coutertops have been out for how many years and this is a problem and they don't know about the problem. I find this hard to belive.
