I installed an underground water supply to a hose spigot near my fire pit on my property, and I'm trying to determine where to install the vacuum breaker. I understand it needs to be installed at the highest point, and since my property slopes uphill toward the fire pit and the spigot rises out of the ground on a post, the highest point would be at the spigot itself. That's where I should install it, correct? I was initially thinking the vacuum breaker needs to be where the copper pipe exits the home where it transitions to a polyethylene pipe because I thought that water held in the poly pipe might be the kind that I wouldn't want to back-flow if a siphon were to form. However, that would mean I'd need to route the plumbing at that point so it juts out of the ground higher than the elevation of my fire pit spigot, i.e. 5 or 6 feet, which would look ridiculous.

Can someone please confirm or correct my thinking on this?
