## Description

Culwell flange the solution to a fatal flaw that no other toilet flange has ever resolved. This product inspired the creation of a ‘new standard’ in toilet flanges in the us and Canada - why architects & engineers are specifying. Made in USA. This revolutionary patented product is engineered to prevent surface leaks, water damage, and costly repairs under and around the toilet that all other toilet flanges fail to protect against. Every flange is designed to anchor the toilet to the floor and seal to the sanitary piping, however, toilet flanges were never designed to seal to the floor… until now! creates an impermeable water-tight seal, thus saving property Owners and managers thousands of dollars in time and repairs over the life of the property. Pay now or pay later. No more costly repairs when the wax ring fails, when toilet overflows, when tub spills over, or when flange breaks. Culwell flange offers increased value to installers, designers, property managers and Owners, while decreasing liability exposure, changing the ‘status quo’. exclusive limited lifetime guarantee on all models. Uses and benefits are in commercial, residential, new construction and remodel/repairs. Culwell flange is the premium choice in toilet flanges– why use any other it is rust and corrosion resistant; superior in strength and will not break like others-withstanding 1000 lbs; protects the integrity of the substrate directly under the flat surface of flange while other brands have holes and crevices that allows waste/water to seep through the flange and absorb into the subfloor (when the wax ring fails or flange breaks); holds closet bolts upright and in place for ease of toilet placement. This product is ideal for tile applications and when the flange is recessed below the finished floor. This patented product is designed for two install options; for use with or without a water barrier membrane. A floor membrane is not applied if the installed intent is not to water-proof the entire bathroom, however because of it's unique flat seal surface the Culwell flange provides added seal protection that no other brand on the market can support. For 100% water-proofing the entire bathroom floor and/or creating a wet room, the Culwell flange can be used with any water-barrier membrane (maximum 30-100 mils thick). please view the demonstration videos for installations with and without a floor covering membrane visit the company website Culwell flange.Com. Other benefits include; use with concrete subfloor- with its flat surface design that prevents eroding under the flange, which causes uneven subfloor and typical flange to break; pier and multi-floor structures with wood subfloor- homes, apartments, dormitories, hotels; mobile and production homes; bariatric/Disability- superior strength for heavy weight transfers and meets ADA weight requirements- preventing a leading cause of broken flanges; wet rooms- no longer restricted to a wall mounted toilet and are now made possible when the sanitary pipe connects through the floor; small spaces- by creating a wet room and installing a toilet in a barrier-free shower area.
