rainwater between tube and rim
Symptom: When I spin my rear wheel I hear water moving along inside.
It only happened three times, each after heavy rain and only when the valves didn't have lock nuts (threadless prestas can't take nuts). My front wheel got no water inside. The other two times this happened were with a completely different wheelset, with threaded prestas but again no lock nuts (just 'casue I forgot 'em). Do the nuts sufficiently cover the space in the rim's valve hole around the valve itself to prevent/reduce rainwater from entering the wheel? My LBS said threadless valves don't ruin pump nozzles as fast as threaded. But should I just stick with threaded valves so I can use a valve nut to keep water out? Or is there some other cause/solution?

just leave the wheel(s) over a heating vent.

Using threaded valves with a nut screwed on will not eliminate this problem, although it might decrease it. After my wife and I did a prolonged ride in heavy rain, there was a decent amount of water in three of our four rims, all of which had threaded valves and a nut installed.

You need to get the water out. It can cause corrosion with eyelets, nipples, and spokes. How much damage may occur depends on the alloys involved and how long the water is present. I lost an expensive race wheel do to water corrosion in a non-replaceable eyelet.

you guys ridin'?
If you ride through water or in the rain, water can enter the rims through the valve stem hole and/or around the spoke nipples. Some rim designs are such that a small "weep" hole can be drilled through the rim to allow the water to escape while riding, with the assistance of the centrifugal force of the spinning wheel. You really need to know the precise cross section of the rim to determine whether this approach is workable. I would be careful in any attempt to seal the rims in some manner (to prevent water intrusion) unless there is some way to vent or drain water that finds it way in through a defect in the seal.
