How do I fix a running American Standard Champion Toilet?

We're here to help you get your Champion® toilet running perfectly.  Because our flush valve designs have been updated over the years, the correct troubleshooting steps depend on the version you have.

To get started, identify which flush valve is in your tank and select the matching image/version below for a guide designed specifically for you.

 NOTE: The following article contains general Champion troubleshooting information.  For accurate instructions and troubleshooting, we recommend referring to the article for your specific valve version.  

If you hear water running in your American Standard Champion One-Piece or Two-Piece Toilet, whether the water is running intermittently or consistently, it is most likely due to one of the four components inside the toilet tank. 

Before replacing any toilet parts, first check the flush valve chain.  It is set correctly if the flush valve opens instantly when you push the handle and closes securely the moment you let go.  The chain should be taut with no slack, but still long enough to allow the valve to form a complete seal.

Determining which part is faulty will depend on a simple leak test you can conduct, which can be found here.

If you have conducted the leak test and determined which part you will need to replace, take a look at the following information to find the specific name and model number of the part.

1.  If the toilet tank water level leaks down to the flapper top, then you will need the Champion Flapper Seal or Flapper Assembly.

        

2.  If the toilet tank water level leaks below the flapper top, then the flush valve will need to be replaced.  There is a unique flush valve for a one-piece and a two-piece Champion toilet.

3.   If the toilet tank water level didn't drop at all when the leak test was performed, this indicates there might be an issue with the Universal Toilet Water Fill Valve part number 7381125-400.0070A. A frequently encountered problem with fill valves arises when continuous water flow leads to an overflow situation. This occurs when the water level surpasses the overflow tube's height on the flush valve. Typically this is caused by debris that has become stuck inside the fill valve, preventing the valve from shutting off. Check out the article, Flushing Out A Toilet Fill Valve before replacing this repair part. If you need assistance with replacing the fill valve, that information can be found here.

 

 

4.   Lastly, a bent or broken trip lever can cause the flapper to remain open, causing water to run. Erratic flushing can occur if the trip lever wears out or is loose.  You can replace the trip lever if the parts above don’t solve the issue. However, trip levers are unique to the specific toilet tank, so locating the toilet model number will be necessary to determine which one you need, take a look at Locating Tank Model Number.
