Conclusion: toilet flaps

AI
Replacing your toilet flapper is one of the simplest DIY repairs you can tackle to save water. Whether you need a single replacement or a multi-pack for several bathrooms, check out our full list to find the best fit for your home.

Frequently Asked Questions

AI
The best way is to remove your old flapper and measure the diameter of the flush valve opening. Most standard toilets use 2-inch valves, while newer, high-efficiency models often use 3-inch valves.
Most universal flappers fit a wide range of brands, but some proprietary systems (like certain Kohler or Toto models) may require brand-specific parts for a perfect seal.
Ensure the chain is not too tight, as this can lift the flapper slightly. Also, check that the rubber seal is seated flat against the valve and that there is no debris preventing a full closure.
