<p>An insulating device 400 suitable for insulating a stopcock (not shown) comprises a main body with a side wall 402 and an upper end wall / cap 208 together defining a cavity 404 within the main body, the cavity being suitable for receiving a stopcock, wherein a handle 210 is provided above a top face of the upper end wall. The side wall is preferably a tubular sleeve, and is dimensioned to form a tight fit within a stopcock chamber, in use. The upper end wall is preferably fixed to the sleeve, but may optionally be removable. A handle loop 210 preferably passes through holes on the cover cap / end wall, or may be integral with the end wall. The thermal insulating material of the main valve / water stop cock is ideally foamed closed cell nitrile rubber material. By having the shape of a tea-cosy / bell / hood, it is easily located over a stop cock / mains tap. By insulating the stopcock, the water within is prevented from freezing.</p> |
