TLDR Review: 24-Inch Gate Extension
Verdict
This Kohler Extra Tall Gate Extension 24Inch is generally well-regarded for its durability and ease of installation, especially if you’re comfortable with basic DIY plumbing. It’s a solid choice for replacing worn-out flappers, especially since many reviewers reported successful fixes for leaks and ghost flushing. However, take care to verify compatibility and read installation instructions carefully, as those picture-based guides can be confusing. If you’re looking for a product that’s likely to last and offers reliable performance, this model is worth considering—but if you want a more foolproof fit, exploring alternative brands like Korky might be wise.
