Condensation under bathroom sink

Hi all,
We own an 07 Greyhawk Sport and sometimes have trouble with water under our sink in the bathroom. I've taken the drain line apart and reassembled it looking for a leak and watched for leaks with the water running as well and never found a leak. I have noticed the hot water faucet valve seems to sweat a lot especially when we run the ac and at this point I'm working on the assumption that sweating is our problem. Has anyone else had a similar problem and if so what did you do about it. If no one else has, should I just replace the valve.

I have not had this problem, but give us a little more detail. How much water are we talking about, a small spot under the pipes, a large puddle?
If the valve is sweating, do you mean on top of the vanity or underneath? I don't think changing the valve will do anything to stop sweating.

If I had anything better to do I would be doing it :)

I've never seen a hot water line "sweat". Cold water line, yes. That can generally be solved with a little foam rubber pipe insulation. A little more detail could help up analyze/solve the problem.

I never saw hot water lines sweat either, but I did have a problem on a plastic sink. When hot water was in the sink, the bowl would sweat. Usually under sink areas stay colder than the living areas, if they are not vented properly.

Another possibility for a water leak (besides sweating, supply line and drain line leaks) is splash water leaking between the basin bowl and the countertop, or leaking around the base of the faucet.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
