I like that warning about using toxic automobile anitfreeze. Some people just see the word antifreeze and aren’t aware that etylene glycol is toxic and can harm the environment.
The anti-freeze professional plumbers use is propylene glycol that is often an ingredient in orange and other flavor sodas. Even so, the EPDM gaskets used as seals in some devices swells and fails from long exposure to glycols. EPDM is the same material used for electrical insulation and automobile window gaskets, but we don’t put antifreeze on them as a practice.
