A malfunctioning toilet can disrupt the comfort and functionality of any home. One of the most common yet misunderstood issues is toilet double flushing — when your toilet flushes twice in one cycle, or only works when you hold the toilet handle down. These issues waste water and signal that something inside your toilet tank needs urgent attention. Thankfully, these problems can be resolved quickly and affordably with the right tools and a little know-how.
At Champion Services, we’ve handled countless calls from homeowners dealing with persistent toilet repairs inside the tank, and the solution often lies in one surprisingly simple component — the toilet flapper. This often-overlooked rubber piece is the silent hero of a functioning toilet. And when it ages, warps, or misaligns, it can lead to inconsistent flushing behavior. From flapper leaking to poorly adjusted chains or levers, we’ll walk you through the detailed steps to fix a toilet suffering from a double flush problem and prevent it from happening again.

Understanding the Causes of Toilet Double Flushing
The first step in solving a toilet issue is identifying the actual cause. Here are some of the primary culprits behind a toilet that double flushes:
1. Flapper Is Leaking or Sticking
A deteriorated or misaligned toilet flapper can cause water to leak prematurely or cause the flapper to rise and fall more than once during a flush cycle. Over time, flappers degrade due to mineral buildup, mold, or simple wear and tear, making them less effective at sealing the tank.
2. Chain Slack or Tension Issues
If you say, “I have to hold down the toilet handle to flush,” it’s likely due to chain issues inside your tank. The chain that connects the toilet handle to the flapper can become too loose (causing incomplete lifts) or too tight (preventing the flapper from sealing). Either way, improper chain length causes flushing inconsistencies.
3. Adjustable Flapper Not Optimized
Modern toilets often come with an adjustable toilet flapper, such as the Fluidmaster PerforMAX, which allows users to regulate how long the flapper stays open. If this dial is incorrectly set, your toilet may flush longer than necessary, or not long enough, leading to a toilet double flushing or partial flush.
How to Fix a Toilet That Double Flushes
Tackling the issue doesn’t always require a plumber. You can bring your toilet back to perfect working order with a few adjustments, the right tools, and some patience.
Step 1: Turn Off the Water Supply
Locate the shut-off valve behind the toilet and turn it clockwise. This stops water flow to the tank, making repairs easier and cleaner.
Step 2: Inspect the Flapper
Lift the toilet tank lid and flush to observe how the flapper behaves. It may need replacing if it slams shut too quickly or bobs up and down. You’ll also want to check for visible damage, mineral buildup, or warping.
We recommend using an adjustable toilet flapper like the Dial-A-Flush flapper, which allows precise control over the flush cycle. You can order a toilet repair kit or replacement parts from Champion Services.
Step 3: Replace the Flapper
Removing the old flapper is simple. Unhook it from the side ears of the overflow tube and disconnect the chain from the handle lever. Snap the new flapper into place, ensuring a tight, sealed fit.
Adjust the dial to a middle setting (typically between 4 and 6). This setting ensures enough water is released to clear the bowl without triggering a second flush.
Step 4: Adjust the Chain Length
Next, reconnect the chain to the adjustable toilet lever or handle. You want about a ½ inch of slack. Too much slack, and the flapper won’t open fully. Too little, and the flapper won’t seal properly. Test the flush and observe whether the flapper stays open long enough for a complete flush.
Step 5: Turn the Water Back On
Restore water to the tank and let it refill. Flush again and confirm that the flapper opens and closes smoothly without holding down the handle. Watch for air bubbles — a good indicator that the flapper stays open long enough for a full flush.
When to Replace Instead of Repair
Older toilets with worn-out internal mechanisms may experience performance issues even with adjustments. If you’ve tried everything and still must hold down the toilet handle to flush, consider upgrading components or the entire toilet mechanism.
Many homeowners in Las Vegas are upgrading to adjustable toilets with modern features that conserve water while ensuring powerful flushing. These systems often have energy-efficient flushing systems, durable components, and intuitive adjustability.
