Kohler GP85160

Expert Review Analysis

The Kohler GP85160 is a genuine 2-inch blue toilet flapper featuring an integrated adjustable float, designed specifically for 1.6 GPF two-piece Kohler toilets like the Wellworth series. It offers a tight seal to prevent leaks and includes durable, chlorine-resistant vinyl construction for long-lasting performance. The product comes with a 5-year warranty and is intended as a direct replacement for failing flappers in compatible models.

✓ Best for: Owners of compatible Kohler 1.6 GPF two-piece toilets, such as the Wellworth series, experiencing flapper failure, leaks, or inconsistent flushing. It is also suited for replacing broken floats in areas with chlorine-heavy water and for customizing fill levels in older Kohler models while maintaining warranty coverage.✗ Not ideal for: Users with non-Kohler toilets or different gallon-per-flush ratings who require universal compatibility. It is not ideal for those seeking WaterSense certified products or ADA compliant fixtures. Additionally, it may not be suitable for users concerned about Proposition 65 chemical warnings or those requiring UL listed components.

Pros

✓Integrated adjustable float allows for precise water level customization to prevent overflow
