FINALLY! The solution to a fatal flaw that no other toilet flange has attempted to resolve.


Save more – seal the floor!

Introducing the world’s only leak proof toilet flange. Culwell® Flange takes the property and the people into account…not just the plumbing! 

The Culwell® Flange is the solution to a fatal flaw that no other toilet flange has ever solved. This revolutionary patent product is engineered to prevent surface leaks, water damage and costly repairs that the traditional toilet flange fails to protect against. Every flange is designed to anchor the toilet to the floor and seal to the sanitary piping. Toilet flanges were never designed to seal to the floor…

UNTIL NOW!

No other product on the market seals to the floor, saving thousands of dollars!

Property Saving

Say goodbye to costly water damage that the traditional toilet flange can not prevent when the wax ring fails, when the toilet overflows, when the tub spills over, or when the flange breaks. (The Institute for Business and Home Safety reports residential insurance payments by toilet seal/flange failures range from $586 – $2,697 per claim)

 

Premium Quality

Setting a new standard with its uniquely engineered flat sealing surface. Its one-of-a-kind blue nylon clamping ring provides added strength and durability to prevent the need for repair or replacement in the future – even withstanding 500 pounds of pull-out force applied to each bolt during lab testing.

 

Peace of Mind

Finally, an alternative to the traditional flange that’s been the status quo for decades and a solution to a product that often fails, backed by Culnat’s exclusive LIMITED LIFETIME GUARANTEE on all Culwell® Flange models. Reduce worries of mold and rotting floors hiding under the toilet and any unforeseen expenses, when specifying and installing it right the first time.

*This product inspired the creation of a new standard, IAPMO IGC 285, published by the International Association of Plumbing and Mechanical Officials (IAPMO)
