If your power flush toilet isn't working the way it should, there are several things that could be causing the problem. Many problems are caused by leaks that are easily corrected, and other problems may require a quick swap of a valve or other component. So, this handy guide will show you how to repair the most common problems with your toilet.

Step 1 - Check for Leaks
One of the most common problems with power flush toilets is leaking. So, you'll want to check common areas where leaking normally occurs. You'll want to check the flush and refill valves and also make sure that the ball cock is working properly. If the valves are not properly opening or closing, or components are not seated properly, leaks can occur.
A leaky flush valve will usually result in water being leaked back into the toilet bowl. A leaky flush valve will cause a continuous flow of water that is simply being wasted. Likewise, a leaky refill valve will cause water to be wasted as well. A leaky refill valve will cause the tank of the toilet to overfill, and excess water will run into the bowl via the overflow pipe.
Step 2 - Make Simple Adjustments
Many times, a power flush toilet can be repaired by simply making adjustments. If your tank is constantly flowing water into the bowl, you may need to adjust the refill valve. You can adjust the water level by bending the float arm. When adjusting the refill valve, ensure that enough water is available for a complete flush. However, don't allow the water to float to the top of the overflow pipe.
If the float is obstructed by other parts of the toilet, you can easily adjust the float arm to one side or the other. If the float is no longer buoyant, unscrew the float and shake it vigorously to determine if the float has been waterlogged or not. A waterlogged float can easily be replaced.
Step 3 - Replace Faulty Valves
If you find a faulty flush or refill valve that can't be fixed with an adjustment, you will need to purchase a replacement valve and install it. The new valve should come with installation instructions.
Step 4 - Replace Other Faulty Components
If the toilet is leaking near the inlet hose you may need to replace a water supply valve. If the toilet is seeping water from underneath the base of the toilet, there is a good chance that the wax ring may need to be replaced.
Most power flush toilet problems are easily corrected if you take the time to do a little research. In fact, there are very few toilet repairs that you should not be able to make on your own.
