The cast-iron mounting plate and clamping collar set into the roof deck and the casing runs down through the structure, so there is no wall thickness to match.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eIs it freeze-proof, and will it drain itself?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes on both. It is a non-freeze design: the valve sits down in the casing below the roof line where it stays warm, and the casing empties through the 1\/8\" NPT drain port each time you shut it off. Pull the hose off before winter so nothing traps water above the valve.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it have a built-in vacuum breaker (anti-siphon)?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo, this model has no vacuum breaker. Where the code requires backflow protection on a hose connection, plan on an add-on breaker at the outlet, or choose a model with an integral vacuum breaker.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDo I need a key to operate it?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNo key.
