A running toilet is more than a minor inconvenience—it’s a hidden drain on your water bill and a potential sign of deeper plumbing issues. Whether you’ve noticed that your toilet isn’t filling properly or you hear a constant trickle long after flushing, the source of the problem often lies inside the tank. Many homeowners don’t realize that a slow-filling toilet tank or a fill valve that is not shut off can waste hundreds of gallons of water daily if left unchecked.
At Champion Services, we understand how frustrating it can be to hear your toilet running all night or deal with inconsistent water levels. That’s why we’ve created this in-depth guide to help you identify, troubleshoot, and resolve these issues yourself, or know when to call in the pros.
We proudly offer handyman and HVAC services in Las Vegas to handle these repairs with efficiency and care. Below, you’ll learn exactly how to fix a toilet that keeps running and discover professional toilet repair tips for long-term performance.
Understanding the Components: What’s Inside the Toilet Tank?
The tank behind your toilet bowl holds all the internal mechanisms that control the flushing process. The most important parts include the fill valve, flapper, float, and overflow tube. If any of these parts are malfunctioning, they can cause the toilet tank to fill slowly, or worse, not stop filling at all.
- The toilet fill valve is responsible for refilling the tank after each flush.
- The flapper seals the flush valve and holds water in the tank.
- The float rises with the water level and signals the fill valve to stop.
- The overflow tube prevents the tank from flooding.
Issues with any of these components can result in a toilet not filling up with water, a fill valve not shutting off, or a slow-filling toilet tank. If you’re using products like Fluidmaster, specific adjustments to the toilet repair fill valve may be needed.
Why Is My Toilet Not Filling Properly? Common Causes and DIY Fixes
When your toilet tank is not filling up with water, or it continues to run after use, there are a few likely culprits. The most common issues are:
1. Misaligned or Worn-Out Flapper
A flapper that doesn’t seal properly allows water to leak into the bowl, which triggers the fill valve to continuously bring in more water. You can fix this by replacing the flapper with a new one, ensuring it seats tightly against the flush valve opening.
2. Improper Fill Valve Adjustment
Sometimes, the toilet fill valve is set too high or too low, which leads to a tank that either overfills or doesn’t fill enough. Adjust the float arm connected to the fill valve to ensure the water stops about one inch below the overflow tube.
3. Clogged Fill Valve
Mineral buildup can cause a slow filling toilet, especially if your home has hard water. Turn off the water supply, remove the fill valve cap, and clean out any debris or buildup using a soft brush or vinegar solution.
4. Chain Length Issues
If the chain that connects the flush handle to the flapper is too short or too long, it may prevent the flapper from sealing properly. Adjust the chain so there’s a slight slack when the flapper is closed.
When a Slow Filling Toilet Tank Needs Professional Help
If you’ve tried all the DIY fixes and the toilet tank is still not filling up with water, the issue may lie deeper in your plumbing system. Problems such as poor water pressure, corroded shutoff valves, or internal cracks in the toilet tank require professional assessment.

Preventative Maintenance: Avoid Future Toilet Repairs
Routine maintenance is key to preventing issues like a toilet fill valve not shutting off or a toilet tank filling slowly. Here are some smart habits to adopt:
- Inspect inside the tank monthly for wear or mineral buildup.
- Clean the fill valve filter if you notice slower water flow.
- Avoid using bleach tablets, which can erode tank components over time.
- Shut off the water when performing repairs to avoid leaks or flooding.
