  • Publication number: 20070157531
    Abstract: A perforated tube made of plastic with a cap on one end and several different size nipples on the other end becomes a potential critter stopper. The invention attaches to condensate drains from central air-conditioning units at the exterior of the building. The invention can also be used on exit drains from swimming pool overflow piping, and on perimeter floor drain gutter systems in screened in lanais. The invention allows the water to exit normally and prohibits the critters from entering the dwelling or clogging up the piping. The invention attaches easily, by friction fit, therefore allowing it to be removed at some point to be flushed out and cleaned. The cap is friction fit also to permit removal and cleaning.
