Penguin Toilets’ Model 524 unit features a patented secondary drain system built within the bowl that adds protection against overflows. This new feature provides two areas of protection from overflows: one from the primary inlet holes and one from the holes under the rim within the toilet bowl. Model 524 is a 1.28-gpf, Water Sense-listed unit with a 3-inch flush valve and a 1000gram MAP score, providing a powerful flush with good bowl rinse.
