Why Your Toilet Won’t Stop Running (And How Home Advantage Plumbing Services LLC Can Help)
Is your toilet constantly running, wasting water—and money—without you even noticing? You’re not alone. A faulty toilet flapper or fill valve is one of the most common yet overlooked plumbing issues in U.S. households. Left unchecked, it can waste up to 200 gallons of water per day, according to the U.S. Environmental Protection Agency (EPA).
If you’re searching for a trusted solution, Home Advantage Plumbing Services LLC specializes in diagnosing and repairing these exact problems quickly, affordably, and with lasting results. Let’s dive into what’s really happening inside your tank—and how to fix it.
What Does a Toilet Flapper Do—and Why Does It Fail?
The toilet flapper is a rubber seal at the bottom of your tank that lifts when you flush, allowing water to rush into the bowl. After flushing, it reseals to let the tank refill. Over time, this rubber component degrades due to:
- Chlorine and hard water exposure
- Mineral buildup
- General wear (most flappers last only 3–5 years)
Signs your flapper needs replacement:
✅ Water keeps running after flushing
✅ You hear “ghost flushing” (random refills)
✅ Dye test shows color leaking into the bowl without flushing
Pro Tip: Place a few drops of food coloring in the tank. Wait 15 minutes. If color appears in the bowl, your flapper is leaking.
What Is a Fill Valve—and When Should You Replace It?
The fill valve controls the flow of fresh water into the tank after each flush. If it malfunctions, your toilet may:
- Overfill and spill into the overflow tube
- Underfill, causing weak flushes
- Make constant hissing or gurgling noises
Modern fill valves (like the Fluidmaster 400A) are more efficient and adjustable than older ballcock-style models. In fact, upgrading to a dual-flush or high-efficiency fill valve can reduce household water use by up to 20%, per the U.S. Department of Energy.

Step-by-Step: Replacing Your Toilet Flapper & Fill Valve (DIY Guide)
While Home Advantage Plumbing Services LLC offers expert installation, many homeowners prefer a DIY approach. Here’s how to do it safely and correctly:
Tools You’ll Need:
- New flapper (match your toilet brand—e.g., Kohler, Toto, American Standard)
- New fill valve kit (universal models work for most tanks)
- Adjustable wrench
- Towels (for spills)
- Bucket
Steps:
- Turn off the water supply at the shutoff valve (usually behind the toilet).
- Flush the toilet to drain most water from the tank. Use a sponge to remove remaining water.
- Remove the old flapper: Unhook the chain and detach it from the overflow tube posts.
- Unscrew the old fill valve: Loosen the nut under the tank (use a towel to catch drips). Lift it out.
- Install the new fill valve: Insert it through the hole, hand-tighten the lock nut underneath, then adjust height so the float sits 1 inch below the overflow tube.
- Attach the new flapper: Hook it onto the posts and reconnect the chain with ¼ inch of slack—too tight causes leaks; too loose prevents full flushes.
- Turn water back on, let the tank fill, and test flush 3–4 times. Check for leaks.
⚠️ Warning: Don’t overtighten plastic nuts—they crack easily! Hand-tight plus a quarter-turn with a wrench is enough.
Flapper vs. Fill Valve: Which Is Causing Your Leak?
Not sure which part is failing? Use this quick diagnostic table:
| Symptom | Likely Culprit | Quick Test |
|---|---|---|
| Constant trickle into bowl | Flapper | Food coloring test (see above) |
| Tank won’t fill or fills slowly | Fill valve | Listen for hissing; check water level |
| Water sprays or splashes during refill | Fill valve | Inspect for misaligned refill tube |
| Random refills every few minutes | Flapper | Often due to warped seal |
Most leaks (about 70%, per plumbing industry data) stem from the flapper—but both parts often wear out together. Many professionals, including Home Advantage Plumbing Services LLC, recommend replacing both components at once for long-term reliability.
