Why Your Toilet Keeps Running and How to Fix It

If you’ve ever walked past your bathroom and heard the sound of running water long after you’ve flushed, you’re not alone. At Mark Johnson & Sons Plumbing, we’ve helped countless homeowners in Ruston and throughout Louisiana fix this exact issue. A running toilet might seem like a minor annoyance, but over time, it can waste hundreds of gallons of water and cost you on your utility bill.

Let’s break down the most common causes of constant toilet running in Ruston and explain how to fix a running toilet in Louisiana, whether it’s a DIY job or time to call in the pros.

Common Causes of a Constantly Running Toilet

There are several reasons your toilet might be running nonstop, but here are the top culprits we see regularly:

1. Faulty Flapper
The flapper is a rubber valve that lifts when you flush and seals the tank afterward. If it becomes warped or worn out, it may not seal properly, allowing water to leak from the tank to the bowl continuously.

2. Improper Chain Length
If the chain connecting your toilet handle to the flapper is too short or too long, the flapper may not close completely. This is an easy fix once identified, but it’s often overlooked.

3. High Water Level
If the water level in your tank is set too high, it can spill into the overflow tube, triggering the fill valve to run constantly. Adjusting the float or fill valve can solve this issue.

4. Worn-Out Fill Valve
The fill valve controls the water flow that refills the tank. If it’s worn out or malfunctioning, your toilet may not shut off properly after refilling.

5. Cracked Overflow Tube
If the overflow tube is cracked or damaged, water will continuously drain from the tank, and the toilet won’t stop running until it’s replaced.

How to Fix a Running Toilet in Louisiana

If you’re comfortable doing basic home maintenance, here are a few steps you can take:

  1. Check the Flapper: Turn off the water supply to your toilet and flush to empty the tank. Remove the flapper and inspect it for signs of damage. Replace it if needed (they’re inexpensive and easy to find at hardware stores).
  2. Adjust the Float: If your water level is too high, try adjusting the float mechanism so the water stops about an inch below the overflow tube.
  3. Inspect the Chain: Make sure the chain has a little slack but isn’t so long that it gets caught under the flapper.
  4. Replace the Fill Valve: If your toilet is still running, consider replacing the fill valve. It’s a bit more advanced, so don’t hesitate to call us if you’re unsure.

Of course, some issues are more complex and may require expert help. That’s where we come in.
