Operating the Flush Valve
Once installed, the Fluidmaster K-507A-008 operates like a standard toilet flush valve. The PerforMAX flapper is designed to optimize water usage per flush. You can fine-tune the flush volume by adjusting the flapper dial. The higher the number on the dial, the longer the flapper stays open for more water flushed.
Adjusting Flush Efficiency
The flapper dial is pre-set to maximum setting (9). To adjust for most efficient flush, continue to adjust the dial down one setting and flush until the toilet is unable to flush paper properly. Once unable to flush, adjust the dial up one for the final setting. (Refer to Video 1, 4:33)

Opretholdelse
To ensure the longevity and optimal performance of your Fluidmaster K-507A-008 flush valve, regular maintenance is recommended:
- Periodically inspect the flapper and gasket for any signs of wear, cracking, or deterioration.
- Clean the flush valve and surrounding tank components as needed to prevent mineral buildup, which can affect performance.
- Ensure the flapper chain has the correct amount of slack (approximately 1/2 inch) to prevent it from catching or being too tight, which can lead to leaks.
- The flapper is corrosion-resistant, but regular checks can help identify any issues early.
Fejlfinding
If you encounter issues with your toilet after installing the Fluidmaster K-507A-008 kit, consider the following common problems and solutions:
- Kontinuerligt rindende vand: Check the flapper for proper seating. Ensure the chain has the correct slack and is not preventing the flapper from closing completely. Also, verify the water level is not too high, causing water to flow into the overflow tube.
- Svag flush: Adjust the flapper dial to allow more water to be released during the flush cycle. Ensure the fill valve is filling the tank to the appropriate level.
- Leaking from Tank-to-Bowl Connection: Ensure the tank-to-bowl bolts and nuts are tightened evenly and securely (but not overtightened). Verify the correct gasket was used and properly seated.
- Noisy Fill: This kit features quiet fill technology. If noise persists, ensure all connections are secure and the fill valve is properly installed.
