This model is the first-ever 1.0 gpf (3.8 Lpf) back outlet toilet with a gravity flushing platform; a feat in water efficiency. The compact elongated ErgoHeightTM bowl allows for the benefits of a standard elongated bowl but in smaller scale spaces that require a back outlet, while also providing added comfort and ease of a taller bowl. The Viper tank optimizes flush speed and quickly refills using a trusted, industry-best Fluidmaster® 400A Fill Valve. A powerful front jet and carefully engineered rim holes maintain a clean and sanitary bowl with every flush. An exclusive, multi-point mounting system, chlorine-resistant flapper, and non-corrosive, tank-to-bowl brass bolts ensure long-lasting stability and tool-free installation, making Viper the professional's choice.\u003c\/p\u003e\u003ch4 class=\"fw-normal mb-0\"\u003eComponents\u003c\/h4\u003e\u003cspan class=\"fw-normal mb-0 sub-header\"\u003e(For finish-specific component item numbers, please see the \u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/M69E\/e3nAlL\/original\/2025_Gerber+US_Price+Book_20250501_Final\" target=\"_blank\"\u003eprice book\u003c\/a\u003e.)\u003c\/span\u003e\u003cul\u003e\n\u003cli\u003eBowl Item Number: GWS21575\u003c\/li\u003e\n\u003cli\u003eTank Cover Item Number: GTC28595\u003c\/li\u003e\n\u003cli\u003eTank Item Number: GWS28575\u003c\/li\u003e\n\u003cli\u003eTank Lever Item Number: G0099001WH\u003c\/li\u003e\n\u003cli\u003eTank with Right Hand Lever Item Number: GWS2857597\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eDownload Data Sheets\u003c\/h4\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/D6yq\/6Mlg2\/original\/GWS20022_SS\" class=\"pdp-resource\" target=\"_blank\" rel=\"noreferrer\"\u003eSpec Sheet Tech Doc\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/lLyv\/1gDXp\/original\/GWS20022_IPL\" class=\"pdp-resource\" target=\"_blank\" rel=\"noreferrer\"\u003eIllustrated Parts List Tech Doc\u003c\/a\u003e\u003c\/p\u003e","brand":"Gerber","offers":[{"title":"White","offer_id":50681304154409,"sku":"GWS20022","price":662.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/2778\/6281\/files\/unnamed_b2071746-c182-4c35-8331-a4d2c8396e5e.jpg?v=1753204639","url":"https:\/\/www.gsdesigncenter.com\/products\/viper-1-0-gpf-4-1-4-rough-in-two-piece-back-outlet-compact-elongated-ergoheight-toilet","provider":"GS Design Center LLC","version":"1.0","type":"link"}
