We have vacuum breakers but my dad will inevitably remove it because he can’t stand that humming sound. He also insists on leaving the hose bib/valve at all times, even when he’s not using it.

I don’t want my parents to accidentally poison themselves or us when we visit.

    That sounds like a bad idea to me. But a simple check valve should keep them safe i think
