How to Find Your Kohler Santa Rosa Flush Valve Model

Wondering how to identify your Kohler Santa Rosa flush valve model? Start by lifting the toilet tank lid and looking inside the tank. You’ll find a 4- or 5-digit model number printed on the tank wall or near the fill valve.

To identify your Kohler Santa Rosa flush valve model, check inside the tank for a 4- or 5-digit number.

This number usually begins with “K-” followed by digits and sometimes letters indicating specific features or color codes. Common models include K-3323, K-3810, K-3811, and K-10491-0.

Each represents different flush valve types and configurations such as the Water-Guard flushing system or Eco Lite tank.

Note this model number carefully, as it helps you find the exact replacement flush valve or fill valve. For precise parts or further help, consult the Kohler website or contact support with your model information.

Testing Your New Kohler Santa Rosa Flush Valve

After installing your new Kohler Santa Rosa flush valve, fill the tank and flush several times to verify it operates correctly.

During testing, focus on these key checks:

Inspect around the flush valve and connections for leaks or water pooling.

Confirm the water level reaches the fill line without overflowing or continuous running.

Listen for unusual noises during refilling, which may indicate installation issues.

Guarantee the flushing mechanism works smoothly, delivering a complete flush each time.

Monitor water usage to confirm efficiency without excessive flow.

Troubleshooting Common Kohler Santa Rosa Flush Valve Issues

Many common issues with your Kohler Santa Rosa flush valve, like continuous running or excessive noise, stem from worn or damaged components.

Start by inspecting the Seal Diaphragm. A faulty seal often causes leaks and improper flushing.

If you hear excessive noise or the toilet won’t stop running, check the Class 5 Fill Valve (GP1083167) for wear and replace it if necessary.

For inadequate refilling or flushing problems, examine the Canister Valve Assembly, especially if you own models K-3810 or K-3811, and replace it accordingly.

Always verify your toilet’s model number inside the tank before ordering parts to guarantee compatibility.

Proper maintenance and timely replacement of these components will restore your toilet’s functionality and prevent further issues.
