Anyone have a trick for city water intake valve?

On the hose bib, I always use a two way brass "Y" splitter, with the junction going to city water having a pressure regulator on it. This allows me to have city water, but have water for other tasks if I need on the outside.

At the same time you're doing that, it helps to add a vacuum breaker / backwash preventer valve on the "other tasks" side. That way, you're protected from anything you do on that side from potentially polluting your city water input feed!
