Drain for Spas (1.5in threaded)

Anti-vortex spa drain, 1.5 inch threaded connection, for spa and jacuzzi pools. The domed anti-vortex cover spreads suction over its whole surface so hair and limbs cannot be held against it — the arrangement expected by entrapment-safety practice; always pair two drains on one line in a spa. Includes body, gaskets, plastic nut and screws. Fit at the lowest point of the spa floor to draw the coldest water to the heater and to allow the spa to be drained.
