Plan is to install a “doggie shower” in an unheated garage, temperature always below freezing in winter. What products to use to allow hot & cold water without turning master valve on & off and draining after each use? Garage is adjacent to utility room in (heated) basement. Any ideas or suggestions appreciated.
You are almost limited to using something like a J R Smith two valve freezeproof anti siphon hose bibb with a hose for the doggie shower. Or two conventional frost free hose bibbs with vacuum breakers and a hose wye to interconect them.
