Baseboard auto-vents?

Hi,

I just replaced my old corroded baseboard vent valves with auto-vent valves from Home Depot. The instructions say to screw down the cap hand tight and then back it off until water drips out at about 10 drops per minute. This dripping is then supposed to stop within about 30 seconds. At this point, the valve is supposed to let out air, but not water. The only problem is if I then open them up slightly, air will come out followed by drips of water. They seem to require a ridiculously fine adjustment of the screw cap and will probably either drip constantly or be sealed tight and not let out any air. Am I doing something wrong or are these things just junk? I was really hoping for something as easy as a Taco high-vent, but those would be too big to fit in the baseboard. Any suggestions??

Thanks
Charlie

    We do not use them on baseboard for the reasons you mentioned, or they will work and then start leaking at a latter date and could be a problem if not caught quickly.

    If this is a residential application then you don't need them. Do you have problems with air? I'd find the source of your leak first and then fix that. Air eliminators (quick vents) for hydronic systems that can be located on the room terminals are problematic. They are usually rendered ineffective in a short period of time and leak causing property damage. I'd install a bleeder in its place so you can get the air out.
