How to Replace the Inner Workings of Toilet

The first step is to turn off the water supply to the toilet. This is typically done by turning a valve located behind or underneath the toilet. If there is no valve, you can also turn off the main water supply to the house.

Step 2: Remove the old flapper.

The flapper is the seal that prevents water from leaking out of the tank. To remove the old flapper, simply lift it up and off the flush valve.

Step 3: Clean the flush valve.

The flush valve is the mechanism that opens and closes the drain hole. Before installing a new flapper, it's important to clean the flush valve to remove any dirt or debris. You can do this by using a brush or a rag.

Step 4: Install the new flapper.

To install the new flapper, simply place it over the flush valve and push down until it's seated. Make sure that the flapper is properly seated to prevent leaks.

Step 5: Turn on the water supply.

Once the new flapper is installed, you can turn on the water supply. Check for leaks around the flapper and flush valve. If there are any leaks, you may need to adjust the flapper or flush valve.

Step 6: Test the toilet.

Finally, test the toilet by flushing it. Make sure that the water flushes properly and that there are no leaks. If everything is working properly, you're all done!

Additional tips:

- If you're not comfortable replacing the inner workings of your toilet yourself, you can always call a plumber for help.

- When choosing a new flapper, make sure it's the correct size for your toilet.

- If you have a toilet with a dual flush, you may need to purchase a special flapper that's designed for this type of toilet.
