Moved into an older house and one of the hose bibs looks like it has an attachment that doesn't seem to want to come off easily (and I don't want to brute force it / break it if avoidable). My questions:
- What is this attachment?
- How can I get it off without damaging the hose bib? (I tried using tongue and groove pliers but it didn't come off easily but didn't want to over do it)
