Buying advice

When choosing a toilet flapper, first check your toilet's flush valve size (commonly 2-inch or 3-inch) and shape. Most modern toilets use a 2-inch flapper. Consider additional features like adjustable cycles for water conservation or built-in cleaning tablets for convenience. For high-efficiency toilets, opt for models with stronger seals to prevent leaks. Always turn off water supply and flush to drain tank before replacing.
