Toilet Won’t Stop Running? Here’s How to Fix It

Sharing is caring!

A continuously running toilet is the least we all want to happen in our bathroom. Leave alone the water bill; this problem will at least keep us away from using the going to the bathroom. The only good news is, fixing a running toilet is considerably easy to fix.

Now, before you can fix it, you need to find the source of the problem. It can be anything from faulty flappers, water levels, broken fill valves, mineral buildup, to water-logged floats.

Here’s how to fix a running toilet:

Faulty Flappers

A flapper is a rubber or plastic cap in your toilet. This cap prevents you from flushing too much water down the drain. Over time, this item can become brittle and cause a faulty seal. If you believe your flapper is the cause of the issue, here is how to fix it:

  1. Make sure your flapper is still soft enough to hold back water. Please be careful and always use a rubber glove while doing this.
  2. Check the flapper chain. Make sure the string is free from anything that may hold its movement. If you need to replace it, you can use a loop of dental floss.
  3. Make sure your flapper is in the right position. It needs to cover the hole to control the water. Your toilet will keep flushing down water if the flapper cannot seal the hole completely.

Broken Fill Valves

A fill valve is an item in your toilet that ‘tells’ the whole unit to start and stop collecting water inside the tank. This mechanism happens right after you flush down the toilet. A broken valve means water will keep pouring the tank.

Usually, submerged float valves indicate broken fill valves. If this happens to you, do not panic. According to Sayan Plumbing of Bergen County NJ, the broken fill valve is an easy challenge. Here are the secret methods they use to deal with this problem:

  • Switch your shut-off valve to the horizontal position. This step will stop water from entering the tank. Next, remove the lid and flush the toilet.
  • Now, move your attention to your toilet’s water supply shank. There is a locking nut right at the bottom of it. You need to unscrew this and remove the whole fill valve assembly. You probably need a bucket to catch any water drainage.

  • Next, install your new valve. Make sure you keep it 1 inch below the edge.
  • Put the threaded end into the bottom of your tank and use pliers to tighten the locking nut until you have a watertight seal.
  • Now get your water supply line and re-attach it to the valve shank.
  • Take the refill tube and place it into the overflow tube. Make sure you put it on the water line to avoid constant refilling.
  • Switch your shut-off valve back to its vertical position. This step will flow the water into the tank. You can adjust the height of the float valve as necessary.

Water Levels

The overflow valve prevents your toilet from overfilling itself and flooding your bathroom floor. We usually recommend keeping the overflow valve around 1 – 1 ½ inch below the opening lid of the overflow tube.

Water-logged Floats

The water-log float is also another common cause. If water ‘sneaks’ into your float, the float will sink and cause the float valve to partially open. To fix this problem, first, you need to make sure that there is no water inside the float. You can do this by unscrewing the float and shaking it. If you heard any sound of water, your best option is to change the unit immediately.

Mineral Buildup

As water flows into the tank, it may leave some minerals behind. As time goes by, they can create mineral deposits and prevent the toilet mechanisms from working correctly. This situation is mostly due to partial seals and the jams the mineral deposits cause.

To prevent this, it is a good idea to check your toilet regularly, especially the tank. Check for any residue that may prevent the whole unit from working correctly. We usually do not recommend to fix the problem if you found any mineral deposits. You will need a professional cleaning service to help you with this. Try looking for licensed plumbers near you and connect with them. They have the right tools, equipment, and experiences to clean your toilet’s flushing system. It is best not to do this by yourself because no one knows how thick and severe those mineral deposits.
