Water drain out slow in 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.

Far more likly the trap under the sink is pluged up or the drain line.
If a drain is properly vented the overflow will have nothing to do with it draining.

I disagree. We have more problems with grid type drains on sinks without overflows, even on new installations, and i guarantee that the drain is not plugged.


To the OP : What kind of drain is it? Is it a typical popup stopper type assembly, a grid, or a mushroom style push and click open and closed?

What is a pulverizer valve in the drain pipe?

The all in 1 units I buy have an overflow built in to the unit. Did you perhaps buy a trailer house counter top sink. How do you know if you did?

I do not have a trailer, I have a home.

It is a typical popup stopper type assembly.

Can someone tell me what a pulverizer valve is?

I was told that that was the problem.
An another guy ask me if it was a countertop that went into a trailer is there a differance on these? I am sure it is for home use.
