Hello. I have noticed that the Spirovent micro bubble resorber has a slight drip. What could be causing this to happen?
Thanks.

    Probably some dirt/ scale got under the float in the unit. Now it does not seal off super well....

    When you replace the head, pull the wire strainer thing out and inspect it as well. I've found they sometimes come apart.

    This is precisely why I refuse to use Spirovents. Seems every darn one of them leaks by after a year or two.

    If you have many air eliminators of any kind that leak often maybe you need to address system water quality. Water in all types of boiler systems should be checked.

    No, it's a Spirovent issue and nothing further. None of the other air eliminators dribble, just the Spiro units. While I fully agree that water treatment can and does play a big role in system longevity, it's irrelevant to the Spirovent problem in 100% of the cases I've handled.

    I probably have over 25 SV and never had a leak.

    Heh, ironically enough I just got home from a job that was installed 7 years ago with a 1" swt Spiro. Guess what was leaking! Water tested out perfectly, just another weepy needle. Honeywell SuperVent in the detached garage installed the same year with the same fluid was clean as a whistle.

    Probably a spec of crud under the seat, it can happen with any brand. Some brands are easier to disassemble and clean.
