Abstract
A safety cover for mounting upon a suction drain that removes water from a jetted tub or spa. The safety cover can handle a high fluid flow intake rate and has a relatively small size, yet is unlikely to entangle the hair of a user and can pass the industry standard five pound pull test. The safety cover has at least one internal wall that acts as a guide vane thereby advantageously tending to reduce turbulence and vortexing of the water as it passes through the cover and into the suction drain. Because turbulence and vortexing of the water is reduced, the possibility that a user's hair could extend through the cover and become entangled thereunder is likewise reduced. Further, because of the stabilized fluid flow inside the safety cover, the cover can have a size that is smaller than otherwise possible without the anti-vortexing interior wall. The interior wall also can extend from the cover to a supporting base to advantageously increase the structural strength of the cover.
