• How to Measure Toilet Flush Button ?

  Sep 11, 2025

  Before replacing or purchasing a new toilet flush button, it’s important to take accurate measurements of your toilet tank to ensure a proper fit.   1. Identify the Hole Location   Toilet flush buttons are usually installed in one of two places:   Toilet tank lid hole: This is the most common type. The hole size on the lid typically comes in three standard diameters: 38mm, 48mm, and 58mm. You can use a ruler, tape measure, or caliper to measure the flush button hole size. Once you know the measurement, select the flush button that matches.   Toilet tank side hole: If the flush button is installed on the side of the tank, there’s no need to measure. These are usually cable-operated flush valves, and most toilet side flush buttons available on the market are universal.   2. Measure and Adjust the Flush Button Rod Length   For top push button toilets, measuring the hole diameter alone is not enough—you also need to check and adjust the rod length. The rod included with a new flush button is usually longer than required, as manufacturers design it to fit different types of toilet tanks. You can cut it down to the correct size during installation. Here’s how:   1. Initial measurement: Without installing the button, place the rod directly through the hole on the tank lid until it touches the flush valve at the bottom. Note the part sticking out above the lid.   2. Install and test: Insert the rod into the flush button, then install the button onto the tank lid.   3. Close the lid test: Place the lid back on the tank and check if the rod pushes down on the flush valve even without pressing the button.   4.Trim gradually: If the rod is too long, trim off a small amount. To avoid cutting too short at once, it’s recommended to trim 5–10mm at a time, reinstall, and test again. Repeat until the length is just right.   3. Conclusion   Measuring your toilet flush button size and properly adjusting the rod length ensures you purchase the right replacement and achieve smooth flushing performance. Following these steps will help you install or replace your toilet push button with confidence.
