How to Fix Overflowing Toilet Tank

Is your toilet tank overflowing? This major plumbing issue is not only inconvenient and messy, but it can also cause severe water damage if it occurs when no one is at home. At Rooter Hero Plumbing, we provide high quality residential and commercial plumbing services for local California and Arizona area clients including toilet repair, replacement and installations. Are you wondering what is causing your toilet tank to overflow? Read below for some helpful information. 

What Usually Causes a Toilet to Run? 

Inside your toilet tank, you should see a white plastic tube in the center. If the float is properly adjusted, the fill valve will shut off as the water level approaches the top of the overflow tube. However, if the float isn’t working correctly, then the water level will continue to rise. Eventually the water will begin to drain into the overflow tube and into the toilet bowl. In extreme cases, the water can even cause your toilet tank to overflow. 

Checking Your Overflow Tube 

First, you will need to check your overflow tube. Do you see major signs of damage or deterioration? Then replace it. If the overflow tube is too big, then it can create major issues as well. This can often happen after new hardware is installed inside the toilet tank. If the tube is too tall, you can cut it down to size. Be careful though, because if you cut it too small, then it will need to be replaced. The top of the tube should sit about an inch below the flush lever. 

Adjusting Your Float and Fill Valve

Next, check the float to ensure that it is properly adjusted to the appropriate water level. If you have a cup-style float, it should have an adjustment rod that will push the float down. Is your toilet an older model with a ball float? Then you can unscrew the ball to extend the arm, which may put more pressure on the fill valve. Or you can turn the adjustment screw on the top of the float with a screwdriver. 

When to Call a Professional Plumber

If you feel at all uncomfortable with adjusting or replacing components inside your tank, it is best to hire a trained professional for the task. Mistakes made during toilet repairs and part replacements can create more issues further down the road and may even lead to hidden leaks and water damage. A certified plumber will have the experience and specialized tools required to fix any toilet problem you may have.
