    That is an air vent. ...and not just any air vent. It is a micro bubble air vent. I have not had much success with taking them apart to repair the float valve inside them.

    Those threads on the end are 1/2" pipe thread. As a temporary fix you can add a 1/2" coupling with thread sealant (like teflon tape or pipe dope) then place a 1/2" close nipple and a 1/2" pipe cap on the threaded end to seal it until the off season. Then you can get a professional to come and repair or replace it.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Take it apart and get the valve inside there cleaned out. But I would wait until the spring. just put the cap on it for now.

    I’d be quite impressed if you can dis and reassemble the valve mechanism on that air purger. Here is a common fix😁. Or buy another and swap the top part.

    I think i've seen the top assembly on supplyhouse.com although it was named in a way that made it hard to find.
