Installed a New Fluidmaster Kit but Still Leaking? Here’s What Might Be Wrong
Installing a new Fluidmaster kit in your toilet is generally a straightforward task that leads to improved function and efficiency. However, if you find that your toilet is still leaking post-installation, it can be frustrating and confusing. Here’s a detailed guide to help you troubleshoot and resolve the issue effectively.

1. Check the Installation
First, ensure that all parts of the Fluidmaster kit were installed correctly. Common mistakes include:
- Improper alignment: The fill valve must be aligned correctly with the overflow pipe.
- Loose connections: Ensure that all connections, especially at the base of the tank where the fill valve locks in, are tight and secure.
- Seal integrity: Check if the rubber seal at the bottom of the flush valve is properly placed and not damaged.
Example: Make sure the fill valve’s height is adjusted so that the critical level mark is at least 1 inch above the top of the overflow pipe.
2. Inspect the Flapper or Seal
A common cause for leaks is a problem with the flapper or the seal:
- Worn out flapper: Over time, flappers can degrade. Even if your kit was new, check for any defects or improper seating at the base.
- Improper seal size: Ensure the seal size matches the specifications of your toilet’s flush valve.
Example: Try the dye test by adding a few drops of food coloring to the tank and see if it seeps into the bowl without flushing, indicating a flapper issue.
3. Adjust the Float
An improperly adjusted float can cause the fill valve to let in too much water, leading to leaks:
- Float too high: If the float is set too high, water can overflow into the overflow tube. Adjust it to ensure the water stops filling at the correct level.
- Float interference: Make sure the float is not sticking or catching on other parts inside the tank.
Example: Adjust the float by turning the adjustment screw clockwise to lower the water level or counterclockwise to raise it.
4. Check for Cracks in the Tank
Even a small crack in the tank can lead to water leakage:
- Visual inspection: Look for any hairline cracks in the ceramic of the tank, especially near the installation points of the new kit.
- Tank integrity: Sometimes, overtightening during installation can cause stress cracks. Ensure everything is snug but not overly tight.
Example: If you find a crack, you might need to replace the tank or apply a waterproof silicone sealant as a temporary fix.
5. Test the Water Supply Line
A leak might not necessarily be from the toilet components but from the water supply line:
- Connection points: Check where the supply line meets the fill valve and at the shut-off valve for any signs of dripping.
- Hose condition: Ensure that the hose isn’t damaged or kinked, which could compromise the water flow and cause leaks.
Example: Tighten the connections with a wrench and replace the hose if it appears worn or damaged.
Conclusion
If you’ve installed a new Fluidmaster kit and are still experiencing leaks, these steps should help you identify and fix the problem. Remember, sometimes issues might be less about the parts and more about the installation process or other toilet components.
