When That Toilet Won’t Stop Running: Hidden Fixes to Try First
A toilet that won’t stop running isn’t just annoying—it can waste hundreds of gallons of water a day and spike your utility bill. For homeowners in Billings and Laurel, Montana, where every drop matters, catching and correcting the cause early is key. At Brown Plumbing & Heating, we often get calls about toilets that seem haunted by a never-ending flush. Fortunately, there are a few hidden culprits you can check before calling in the pros.
Why Toilets Run in the First Place
Your toilet has a few basic moving parts inside the tank: the flapper, the float, the fill valve, and the flush lever. When one of these malfunctions or gets misaligned, the toilet may constantly try to refill, leading to that continuous running sound.
Fix #1: Check the Flapper
The flapper is the rubber seal at the bottom of the tank that lifts when you flush. If it’s worn out or not sealing properly, water will leak into the bowl and the tank will keep refilling.
What to do: Push down gently on the flapper with your hand. If the running stops, it’s likely the flapper is the problem.
Fix: Replace the flapper—it’s a cheap part and easy to install without tools.
Fix #2: Adjust the Float
The float controls when the fill valve shuts off. If it’s set too high, the tank will overfill and water will spill into the overflow tube—causing constant running.
What to do: Look for the float and gently push it down while the tank fills. If the running stops, adjust the float lower using the adjustment screw or clip.
Fix: Reposition the float so the water stops filling about an inch below the overflow tube.
Fix #3: Inspect the Fill Valve
Sometimes the fill valve itself is faulty or worn out, especially in older toilets.
What to do: Listen closely—if the sound is a faint hiss, the valve might be leaking internally.
Fix: You can replace the valve assembly with a universal kit from the hardware store, or call a plumber to ensure the right fit.
Fix #4: Look for Chain Issues
If the chain connecting the flush lever to the flapper is too tight or tangled, it can keep the flapper from sealing.
What to do: Open the tank and check the chain. It should have a little slack.
Fix: Adjust the length so the flapper closes fully without being tugged.

In Billings and Laurel, where water conservation and winter-proof plumbing are important, a running toilet isn’t just a nuisance—it can cause higher utility bills, excess wear on your plumbing, and even risk frozen pipes if left unchecked during cold months. It’s worth addressing early.
