During dry spells it automatically keeps a \u003cstrong\u003elow reserve of water\u003c\/strong\u003e in the tank from your mains or pump supply — so the services fed by the tank keep running, while \u003cstrong\u003eleaving capacity for the next rain\u003c\/strong\u003e to fill.\u003c\/p\u003e\n\u003cp\u003eHere's how it works: as the tank empties, a \u003cstrong\u003eweighted float\u003c\/strong\u003e travels down its cord and sits on the bottom stop, which opens the valve. The valve runs until the float lifts clear of the stop. When it rains, the float simply rises and falls with the water on its \u003cstrong\u003e8.2 ft (2.5m) cord\u003c\/strong\u003e — so the Partfill \u003cstrong\u003eonly tops up when rainfall isn't enough\u003c\/strong\u003e to keep the level above the bottom stop.\u003c\/p\u003e\n\u003cp\u003eThe valve installs \u003cstrong\u003ethrough the side wall of the storage tank\u003c\/strong\u003e, mounted above the overflow level to prevent backflow, and Jobe rates it for \u003cstrong\u003eall makes and models of rainwater harvesting tanks\u003c\/strong\u003e.
