Finally a toilet with overflow protection. Think about it， for years， sinks and bath tubs have had overflow drains. Penguin Technology has designed a toilet that allows the contents to drain out through a separate line in the event of a clog in the main trap. This secondary drain system adds protection to a toilet against overflow. Ready for use in new construction or use as a drop in replacement for all standard toilets. No need to re-pipe or replace the existing plumbing system. Simply remove the old toilet and install the new Penguin toilet. If a blockage occurs and the toilet clogs up， water continues to rise until it reaches the primary overflow holes in the back of the bowl. At this point， the water drains through the secondary system bypassing the main trap and drain. Relax， knowing that you are protected from messy and potentially damaging and costly toilet overflows. cUPC， WaterSense and ADA Compliant.
