I have an ASSE 1011 vacuum breaker teck 12 B64.2 attached to a hose bib, with no set screw. How do I remove it?
I have attached two pictures.

Thank you for your help.

Believe it just threads on. Note the wrench flats in the picture.

Thank you, I thought that was the case but it doesn't want to move. I am concerned about using too much force.

I am not sure if yours has no screw at all or the screw is broken most of the vacuum breaker come with the screw and some the inspector breaks the screw, if no screw at do as ma0641 says, if screw is broken watch the Youtube below, Thanks.

As stated in first post - it screws on. It will take some effort to untie it but it can be done.

Thank you to both of you, I have it figured out now. Cheers
