The divertor is a positive flow system. In the down position, water will flow out the molded spout in the porcelain only. Pull to the diverted position and the water will go to the spray only. Divertor and vacuum breaker are in the center column. Rough dimensions will fit Kohler and Toto bidets.
Center diverter requires a 1 3/8" cutout (may not fit Kohler bidets, with 1 5/16" cutout)
Pop-up requires a 1 1/4" cutout (may not fit Kohler bidets, with 1 5/16" cutout)
