ABSTRACT:
A combined vapor barrier and water assembly for securement to the underside of covers of heated water tubs and pools stands by and around an intentionally made drain opening in an otherwise water tight cover, to provide a drain passageway to be used, if necessary, whenever rain water might unwantedly enter the interior of the cover, and while standing by, to provide a vapor barrier preventing heated vapors from rising upwardly through the drain passageway. In a preferred embodiment, at least two dense weave cloth members, spaced apart, each extend completely across the cross section of the drain passageway, while positioned within a hollow contoured housing of the assembly, which is adapted to be secured to the underside of the cover round the intentionally made drain opening, to provide the drain passageway for the exiting rain water that might unwantedly collect in a cover which was originally watertight.
