How to Fix a Running Toilet with a Button Flush

Ways to fix a running toilet issue

It doesn’t matter whether the toilet you use comes with a water-saving or standard flushing system; you can always fix a worn-out button using the same method. Having said that, there may be a difference in the strategy you use to repair a toilet that doesn’t flush at all.

Let’s explore the steps below:


Cut off the supply of water.

For toilets with isolating valves, it is easy to cut the flow of water without restricting the water supply to your entire house. If it isn’t available in your toilet, stop the water supply using the stopcock below the kitchen sink. Find a piece of metal with the inscription “W” or “Water.”


Lift the cistern

Gently lift the cistern top and detach the refill tube. Keep the lid in a safe area and take out the old button. This task should be simple by removing the back nut fitting that the push button is securely affixed in. Ensure you wipe the outer edge and rim of the hole to prepare it for a new button.

Empty the cistern.

Drain the cistern of water by flushing the system. This lets you clear out the entire cistern. There are a variety of ways to carry this out, and it will simply depend on the kind of system you have. If there is still a small amount of water remaining, don’t fear. Later, you can take care of it.

Remove the cistern

It is impossible to work on the toilet push button without first detaching the toilet tank. Use your screwdriver and unscrew the nuts that fasten the tank to the wall. Find the two butterfly nuts below the cistern and remove them to lift the cistern away from the bowl. Set aside all bolts and nuts. Disconnect the pipe that supplies water to the tank. Next, drain the water left in the tank and lower the toilet lid.

Cover the lid with a towel and gently place the cistern atop it. Clean water that may have spilled at the place the cistern is.


Take away the old flush valve.

Take away the old flush valve. Find a gasket shaped like a doughnut at the base of the cistern. Gently take it out and use the plier to loosen the back nut that affixes the flushing mechanism in position. Remove the metal clamp and set it aside. Examine the doughnut washer to see if it is in great shape. It is reusable, even though your flushing system has a washer. Lastly, detach the flush valve within the tank. You might have to wiggle it a little to make it come out smoothly from the hole.

Install a new flushing system.

It is noteworthy that it may be difficult to replace some types of flushing mechanisms. At this stage, remove the new mechanism from its box. Take out the doughnut washer and, with your hand, unscrew the nut. Raise the new seal to balance securely and firmly at the base of the unit. Next, push the valve through the cistern and tighten it firmly. Return the doughnut gasket to its place. If it’s reusable, there is no need to get a new one.

Insert the cistern back into its position

Insert the cistern back to its position by placing the two bolts back into the slots at the base of the tank. Screw the butterfly nut to secure the cistern to the toilet bowl tightly. Ensure you use your screwdriver to fasten the screw that affixes the tank to the wall. Look around and find out if everything is running smoothly; you wouldn’t want any leakage or drips.

Ensure the flush valve is positioned correctly.

Ensure the fill valve is placed in the right position. This will help the float to let water pass through without any hindrance or obstruction. You can make adjustments to conserve water but check first if it is stated in the manual.

Change the flush button.

It is simple to install the push flush button. All you have to do is remove the back nut, insert the button and re-screw the nut. Feel free to a shroud if your button has it. However, if your button fits neatly, you may leave it out. Attach the button to the system and shut the lid if completed.

Reconnect your water supply

Turn on the supply of water. Ensure everything is working smoothly. You can run a test by flushing it multiple times. Look out for any leakage or dribble. If the problem still persists, it may be smart to replace your toilet.
