That Hissing Sound Is Costing You Money
If your toilet never seems to stop running — that faint hissing or trickling sound that goes on long after you've flushed — you're not imagining it. A running toilet is one of the most common plumbing problems homeowners in El Dorado, KS deal with, and it's one of the most wasteful. A single running toilet can waste up to 200 gallons of water per day. That adds up fast on your Butler County water bill.
The good news: the fix is usually straightforward once you know what's causing it. Here's a breakdown of the most common culprits and what to do about each one.
Common Causes of a Running
Toilet
1. Worn or Warped Flapper
The flapper is the rubber seal at the bottom of your toilet tank. When you flush, it lifts to let water into the bowl, then drops back down to seal the tank so it can refill. Over time, flappers warp, crack, or accumulate mineral buildup — especially in areas with hard water like El Dorado.
When the flapper doesn't seal properly, water continuously leaks from the tank into the bowl. You'll often hear a constant trickle even when no one has used the toilet.
Fix: Flappers are inexpensive and usually easy to replace. Turn off the water supply valve behind the toilet, drain the tank, unhook the old flapper, and snap on a new one. Make sure you match the size and style to your toilet model.
2. Faulty Fill Valve
The fill valve controls how water refills the tank after a flush. If it's worn out or damaged, it may not shut off correctly — causing water to keep running into the tank and eventually overflow into the bowl through the overflow tube.
You can test this by removing the tank lid and watching the water level. If it's rising above the overflow tube, your fill valve isn't shutting off when it should.
Fix: Fill valves can be replaced as a DIY project, but if you're not comfortable working inside the tank, a local plumber can handle it quickly. Sunflower Plumbing services El Dorado and all of Butler County — we can be out fast.
3. Float Set Too High
The float is the mechanism that tells the fill valve to stop adding water once the tank is full. If the float is set too high, the water level rises above the overflow tube and drains constantly into the bowl.
Fix: Adjust the float arm or the float height (depending on your toilet style) so the water level sits about one inch below the top of the overflow tube.
4. Damaged Overflow Tube
If the overflow tube itself is cracked or the wrong height for your tank, water may drain continuously even when everything else is functioning correctly.
Fix: This typically requires replacing the entire flush valve assembly — a job that's doable for experienced DIYers but usually faster with a plumber.
5. Chain Issues
The chain connecting the flapper to the flush handle can also cause problems. If it's too short, it holds the flapper open constantly. If it's too long, it can get caught under the flapper and prevent a proper seal.
Fix: Adjust the chain length so there's about half an inch of slack — enough to lift freely but not so much that it tangles.
Should You DIY or Call a Plumber?
Minor fixes like replacing a flapper or adjusting the float are reasonable DIY repairs for most homeowners. But if you've already tried those fixes and the toilet is still running — or if you're dealing with an older toilet, corroded parts, or you're not sure what you're looking at — it's time to call a pro.
Running toilets can also be a symptom of bigger issues, like a cracked tank or supply line problem. Getting a trained eye on it early saves you from a larger repair down the road.
