Why Your Toilet Keeps Running and How to Stop It

A running toilet wastes water and makes a noise that drives you mad. If your toilet keeps running, the problem is often simple. Many people in Hawthorne, CA call Mr Harris Plumbing & Handyman for quick help. Our Plumbing Service team fixes this every day.

A running toilet feels small, but it can cost a lot over time. You can try a few simple checks yourself. If you do not want to do it alone, a friendly plumber can fix it fast and clean.

What makes a toilet run?

  1. The flapper is old or not sitting right.
  2. The fill valve keeps letting water in.
  3. The float is set too high.
  4. The chain is too short or too long.
  5. Water leaks from the tank into the bowl.

Each part has a name. The tank holds water. The bowl is the part you sit on. Inside the tank, the flapper seals the bottom. The fill valve lets water back in after a flush. The float tells the valve when to stop.

Easy steps to stop it (try these first)

  1. Turn off the water. Find the small valve behind the toilet and turn it clockwise.
  2. Take the tank lid off. Put it on a towel so it does not break.
  3. Watch what happens when you flush. See if water keeps moving.
  4. Check the flapper. Push it down. If the water stops, the flapper is the problem.
  5. Check the chain. It should have a little slack. If too tight, the flapper can’t close. If it’s too long, it can get under the flapper.
  6. Look at the float. If the float is too high, the water will keep filling. Bend the arm down a little or move the clip to lower the water level.
  7. If the fill valve keeps running, it might be old. Replacing the fill valve is cheap and easy for a plumber.

If a rubber flapper looks cracked or stiff, replace it. Flappers are cheap at hardware stores. They fit most toilets. You only need a few minutes to swap one out.

When to call professional Plumbing Services

If you tried simple steps and the toilet still runs, call a plumber. Some issues hide deep inside the tank or in the pipes. Mr Harris Plumbing & Handyman offers fast, honest help in Hawthorne, CA. A trained plumber can:

  • Replace the fill valve or flapper the right way.
  • Reset the float for the right water level.
  • Replace old parts so the toilet stops leaking.
  • Check for hidden leaks that raise your water bill.

A pro can also test the seal and the refill tube. They use the right tools. That saves time and stops the problem for good.

Tips to avoid a running toilet later

  • Test your toilet every few months. Watch the tank after a flush.
  • Replace old rubber parts once a year if your toilet is older.
  • Use a gentle cleaner. Harsh chemicals can damage rubber parts.
  • If your pipes make noise or the water pressure jumps, tell a plumber. Small changes can mean a bigger issue soon.

Quick fixes you can do today

  • Drop a few food coloring drops into the tank. Wait 10 minutes. If color shows in the bowl, you have a leak.
  • Tighten the chain if the flapper does not seal.
  • Clean around the flapper seat. Dirt can keep the flapper from sealing.
  • Lower the float if water fills too high.

These small steps often stop the running. They cost little and take little time.
