What to Do When Your Toilet Won’t Stop Running

A constantly running toilet is one of those plumbing problems that can sneak up on you. It might start as a faint trickle of water or a quiet hum from the tank, but before long, it becomes a steady sound you can’t ignore. Beyond being annoying, a running toilet can waste a significant amount of water, sometimes hundreds of gallons a day, which can drive up your utility bills and strain your plumbing system.

If your toilet won’t stop running, there’s no need to panic. The issue is often simple to fix if you know what to look for. In this post, we’ll walk through the most common causes of a running toilet, how you can troubleshoot it yourself, and when it’s time to call a professional who specializes in plumbing Idaho Falls for help.

Why Your Toilet Keeps Running

Inside every toilet tank is a small system of parts that control how your toilet flushes and refills. When one of these parts wears out or gets out of alignment, the tank may fail to shut off the flow of water after a flush. Here are the most common reasons your toilet might keep running:

1. A Worn-Out Flapper:
   The flapper is a rubber seal at the bottom of your toilet tank. When you flush, it lifts to allow water to flow into the bowl. Over time, it can become warped, cracked, or covered in mineral buildup, preventing a proper seal. If the flapper doesn’t seal correctly, water continues to leak into the bowl, forcing the tank to refill endlessly.
   
   

2. A Faulty Fill Valve:
   The fill valve regulates how much water enters the tank after each flush. If it malfunctions or gets clogged with debris, it may not shut off properly once the tank is full.
   
   

3. An Incorrect Float Setting:
   The float determines when the tank has enough water. If it’s set too high, water will continuously overflow into the overflow tube, causing the toilet to run constantly.
   
   

4. Mineral or Sediment Buildup:
   Idaho Falls has hard water, which means minerals like calcium and magnesium can accumulate inside your toilet tank. Over time, this buildup can cause the moving parts to stick or wear out faster.
   
   

Understanding these components can help you determine whether you can fix the issue yourself or if it’s time to call a local expert in plumbing Idaho Falls for assistance.

How to Fix a Running Toilet

If you’re comfortable with basic home repairs, you can often fix a running toilet without much trouble. Here’s a simple step-by-step guide:

Step 1: Turn Off the Water Supply
Locate the shutoff valve near the base of the toilet and turn it clockwise to stop the water flow. This prevents the tank from refilling while you work.

Step 2: Remove the Tank Lid
Lift the lid carefully and set it aside on a towel or flat surface. Inside, you’ll see the flapper, fill valve, float, and overflow tube.

Step 3: Check the Flapper
Press down on the flapper with your finger. If the running water stops, the flapper is likely the issue. Try cleaning it and the area where it seals. If it’s damaged, warped, or covered in buildup, replace it. Flappers are inexpensive and easy to install.

Step 4: Adjust the Float
If the water level is too high, adjust the float arm or the screw on the fill valve to lower it slightly. The water should stop about an inch below the top of the overflow tube.

Step 5: Inspect the Fill Valve
If neither the flapper nor the float seems to be the problem, the fill valve may be worn out or blocked. Replacing it is often the best solution. Many replacement kits come with easy-to-follow instructions and can be installed in less than an hour.

After completing these steps, turn the water supply back on and flush the toilet a few times to see if the problem is resolved.

When to Call a Professional

While many running toilet issues are easy to fix, some are signs of a deeper plumbing problem. If you’ve replaced the flapper and adjusted the float but the toilet still won’t stop running, it’s time to call in a professional.

A plumber who specializes in plumbing Idaho Falls can quickly diagnose and repair the issue. They can check for hidden leaks, worn-out seals, or mineral buildup in your home’s water system. Professional plumbers also understand local water conditions and can recommend the best parts and maintenance methods for long-lasting results.

You should also call a plumber if you notice:

• Water pooling at the base of the toilet.
  
  

• Strange gurgling sounds when the toilet refills.
  
  

• A sudden spike in your water bill.
  
  

• Rust or corrosion inside the tank.
  
  

Ignoring these issues can lead to larger, more expensive plumbing repairs down the road.

Preventing Future Problems

Once your toilet is fixed, a little maintenance can help prevent it from running again. Here are a few simple tips:

• Clean your toilet tank every few months to remove mineral buildup.
  
  

• Check the flapper and other parts annually and replace them when they start to wear out.
  
  

• Avoid using chemical toilet tablets, as they can damage rubber seals over time.
  
  

• If you live in an area with hard water, consider installing a water softener to reduce mineral buildup.
  
  

Taking these preventive measures can extend the life of your toilet and reduce the need for future repairs.
