5 Ways to Erase Running Toilet Issues


Having a toilet that runs all the time is a real frustration. Not only that it gives too much noise, but it can also double or triple your water bill. Do you know how to fix a broken toilet? Here are some easy jobs that you can do. If you doubt your expertise, calling a professional help is still the best choice.

Locate the Leak

The water on the holding tank may continuously leak into the bowl, and this is typically the result of the malfunctioning re-fill mechanism of the toilet. The usual issues associated with a running toilet are broken fill valves, malfunctioning flappers, water level problems or a water-filled float.

Broken Fill Valve

The fill valve controls the water that flows to your toilet tank, and if it breaks, you should expect a continuous flow of water.  Here’s what you need to do:

  • Shut off the toilet’s water supply hose and place a small bucket under it. Remove the lid from the tank and flush the toilet until the tank gets empty.
  • Unscrew the lock nut that goes to the water supply shank. Remove the whole valve assembly. The empty water bucket will hold any water drainage.
  • Install the new valve. The threaded end should go in the tank base’s hole. Tighten the lock nut by hand and gently turn it using a pair of pliers to prevent the fixture from cracking.

Malfunctioning Flapper

The flapper is the rubber cap that holds the water in the tank and prevents drainage. As it gets old, it cracks and no longer forms a tight seal.

  • Flush the toilet and see how the flapper is working. If the chain connected to it gets tangled, replace the chain or use a string with the same length.
  • Check the hinge that connects the flapper to the bottom toilet tank and see if anything sticks.
  • If the flapper sits on the tank shadily, adjust it.

Improper Water Levels

 If the water level in your holding tank is the issue, you may need to adjust the float.

  • Check if the water level is about an inch below the overflow tube. Adjust the float lower to reduce the water level in your tank. The low flush toilet can save you money.
  • Check if the float is filled with water. If it is, you need to get a replacement.

Mineral Deposits

Lime and calcium are the usual mineral deposits which if not removed, can cause faulty seals and possible jams.

  • Take the cover off the holding tank and check for mineral build-up in the tank or on the mechanisms.
  • If there are mineral buildup, deep clean it. You may need a professional plumber to get it done right.
