Toilet Flush Valve Leaking: How to Repair It

The good thing is this: this kind of issue is not too complicated to fix and you can even do it by yourself. The gist is this: it involves removing the tank from the bowl so you can replace the flush valve. While that sounds simple, here’s how you do it:

• Remove the tank’s lid.
• Shut off the water. Do this by turning the shut-off valve clockwise.
• Drain water out of the tank. Remove as much water as possible by holding down the flush lever until the tank is completely flushed.
• Use a sponge to dry up remaining water. Not every drop of water will be flushed out and as such, you need to do additional cleanup. This is a necessary step because it’s better to work with a blank and clean canvas. It makes everything flow smoother as well.
• Cut off the connection of the water supply tube or hose from the tank.
• Disconnect the flapper chain from the tank lever arm.
• Remove the screws holding the tank to the bowl. You might want to spray penetrating oil before attempting to loosen the screws.
• Using a long slotted screwdriver, reach into the tank to prevent the tank bolt from turning. Remove tank bolts when everything is clear.
