Waterway Low Profile drain assembly

This Waterway drain assembly allows water to exit by gravity. It should never be used with a pump to suck out the water, as there is no protection against entrapment. The connection socket has a 90° angle to minimize the depth needed in the spa shell.

The gasket is included.
