Product Overview

Solidly engineered for worry-free performance, plumber-trusted Viper toilets are designed to consistently deliver a bowl-clearing flush. A tall, narrow tank design with 3" flush valve and an extra-large dual-fed siphon jet power water into and around the bowl for a thoroughly cleansing wash. Large front rim holes send a powerful surge of water that help keep the bowl streak-free. A proprietary, fully glazed 2" trapway provides virtually clog-free performance. A corrosion-resistant rigid flapper ensures consistent operation while the reliable Fluidmaster 400A fill valve quickly and quietly refills the tank. Viper's elegantly tapered tank with tight-fitting lid and slightly flared bowl make this exceptional toilet a perfect addition to any bathroom or powder room. To save time on installation, extra-tall bolt caps eliminate the need for on-site bolt cutting. Plus, Gerber's exclusive multipoint mounting system and non-corrosive brass tank-to-bowl bolts provide ease of installation and lasting stability, making it ideal for both new installations and replacement applications. With Gerber's industry-leading, 15-year warranty on parts and components and a limited lifetime warranty on vitreous china, you'll get Set-It-and-Forget-it assurance and leave toilet troubles behind with Viper.
