Going to the toilet should be a seamless experience, and the best toilet flush valves can help you make it one. These valves are positioned within your flush tank and are available in various sizes. Not every size is compatible with your tank, so you need to be careful about what you buy. The typical rule of thumb here is that the bigger the valve, the better the flow of water. The options we have listed here use much less water than traditional valves, which means you can save gallons, reduce your water bill, and be kind to the environment.
