    Watts 'HAV' automatic radiator bleed valve?

    Any actual experience with this valve? They bleed air when dry and shut off when the material in it gets wet and swells. So they can be installed on radiators in any orientation.

    Do they work well for years, or do they leak or stop working?

    I just installed one on a Runtal baseboard that was slowly collecting air and then becoming noisy. It was almost magical: I opened the shutoff valve in the basement, and by the time I got to the 1st floor the baseboard (previously drained to install bleed valve)  was full of water and yet the bleed valve hadn't spewed any water. But I don't know about the long term.

    depends on how often

    it goes dry/ wet. Typically once they vent air they shut down unless the system is drained down. Or sometimes first start up in the fall they will vent and seal.

    Some brands have a built in ball check so the end can be completely removed, replaced or removed to prevent theft or damage.
