Until recently years while using RV parks around the country I had never seen one of these things. I had to ask when I began to find them. Never had such a thing when growing up and don't have them at our current home in New Jersey. If they are there for the sole purpose of preventing back-flo from my garden hose I can, with no reservations, do without. Since I was a kid I have drank water from my garden hoses and will still do it so if codes require them and sale of my Villages home depend on them I can always replace them. Easy-Peasey. So, I for one, plan to remove them on my next trip to the Villages and never look back.
