How to Fix Toilet Flush Button | Step by Step

Actually, you can do this job in two ways. You can either fix the flusher or change the flush button of the toilet. In this article, we will talk about both meth methods. So, let’s start-

Method 01- How to Fix a Flusher of a Toilet:

If the flush button of the toilet doesn’t work then your toilet has the flusher problem. You have to fix the flusher. There are mainly 2 top-flush models are available in standard-flush model and water-saving model. The models are operated by a pushing button or a pulling rod on the top of the tank. Both of these operations activate the flush mechanism and if the toilet doesn’t flush then most probably there is a problem with the flush mechanism. You can diagnose the problem with a simple troubleshooting procedure. You can fix the flusher easily by replacing a part of the toilet based on the brand, in most cases. Let’s discuss about the procedures-

Button Flush:

-First of all, lift off the cover of the tank and balance it on the edge of the toilet’s tank. Now, look at the flush mechanism. Look at the mechanism consisting of the button assembly. The button assembly should have a rod extending at the underside of the cover. You’ll also find a lever that fits onto the end of that rod. If you find the lever broken, simply pull the lever off. Now, pull off the hose which is connected at a side and go and get a new lever and replace the lever.

-Secondly, if the lever is okay, then it’s time to check the button mechanism. To check, push the button several times and notice if the rod pushes of not each time. If the rod doesn’t push each time, then pull off the lever and drop that into the water tank of the toilet. Get a screwdriver and unscrew the nuts that secure the button mechanism at the underside of the top and remove it. You may use adjustable pliers. Now get a new button mechanism and replace the old one with the new one.

-If the rod pushes each time when you push the button then it seems okay and you should now check the flush valve. Get an ice cream stick and insert it at the end of an artist’s paintbrush handle onto the port on the top of the flush valve where the rod is fitted. Now push down to flush and notice the toilet. If the toilet doesn’t flush, then install a new flush valve. It’s easy but if you still feel unworthy then you may enlist a plumber.




  • Remove the knob from the end of the rod by unscrewing that goes through the tank cover’s top side. Now, spray lubricant on the rubber grommet which keeps the system sealed. Spray it where the rod goes into the hole.
  • Now, push down the on the end of the rod and take the tank cover off. If necessary, use vice grip and lift up the cover enough to grip the rod. Do it underside of the cover. Now, take the rod out of the grommet and set the tank cover aside.
  • After that, fit the vice grip onto that rod. Now, rotate it a bit several times each way as you pull upward. Mineral deposits can be built up in some cases that prevent the rod from pulling upward. Clean the mineral deposits and if the toilet flushes then, reattach the cover of the tank in reverse order and secure it by screwing the knob. And unfortunately, if the toilet doesn’t flush, then get a new flush valve or mechanism (which is broken) and replace it. You can call a plumber if you find it a hard task.

Re-Fit the Cistern:

Now, get the cistern back onto the bowl of the toilet. Be careful and make sure you line up everything and get the bolts back in place through the screw holes. Pop the wing-nuts back and tighten up them too and secure the cistern to the wall by screwing up. Finally, re-attach the cold water feed and tighten the pipe up. You’re done primarily.
