How to Fix a Toilet Flush

Tools you’ll need to fix a toilet flush:

• Replacement Flush Valve
• Channel-Locking Pliers
• Adjustable Wrench
• Replacement Flapper
• Sponge
• Towels
• Bucket
• Penetrating Oil
• Large Slotted Screwdriver
• Plumber’s Wrench

1. Disabling the Water Supply

Firstly, remove the lid from your toilet tank, enabling you to disable the water supply by turning the shut-off valve clockwise. Hold the flush lever down to drain as much water as possible out of the tank, and use a sponge or towel to get rid of any remaining water.

2. Disconnect Toilet Attachments

Disconnect the water supply tube or hose from the tank, the flapper chain from the tank lever arm, and the refill tube which is attached to the top of the overflow pipe. Apply penetrating oil to bolts situated underneath the tank, and proceed to unscrew them, detaching the tank from the bowl.

3. To the Tank!

From there, you can use an adjustable wrench to loosen and eventually remove tank bolts. This will enable you to lift the tank from the bowl and set it to one side, making it much easier to work on. The locknut which is holding the flush valve to the tank should be unscrewed using a plumber’s wrench, so the old flush valve can be removed.

4. Installing your new Flush Valve

Follow manufacturer instructions to install your new flush valve in the same way you removed the old one. When installation is complete, use tank bolts to re-attach the tank to the bowl, the flapper chain to the flush lever arm, and the fill tube to the new overflow pipe.

5. Completing your new Toilet Flush Installation

You’re now ready to reconnect the water supply to the tank. Turn on the water, test your new flush valve and check for leaks.
