How To Fix A Running Toilet

 

Plumbing has come a long way since the old days. Before indoor plumbing started, toilets were nonexistent. The only option for using the bathroom was an outhouse, or a bush. Since our plumbing has come so far, we rarely think about our toilets and plumbing. However, even though plumbing is definitely more efficient and sanitary now, issues still come up. For example, has your toilet been running nonstop? Not only is this annoying, but it wastes water, too. Read more to learn how to fix a running toilet today.

 

How To Fix A Running Toilet: 3 Common Problems

There are typically 3 problems that may be causing your toilet to run. A broken flapper, an unaligned float, or wrong fill tube length are the most common causes for a running toilet. We’ll walk you through each one and how to address them.

 

A Troublesome Flapper

A flapper is a part inside the toilet tank that acts as a drain plug. When you flush the toilet, the flapper lifts up to let the water fill the bowl and flush it out. If the internals of your toilet are old, they break down from constant contact with water and minerals. So, if the flapper is the issue, its seal is likely the culprit.

If the seal on the flapper is bad, we suggest replacing it. To do this:

  1. Buy a new flapper like this.
  2. Before you remove the old flapper, shut off the water supply. The supply line valve should be close to the toilet’s base.
  3. When you remove the flapper, pay close attention to how it attaches to the toilet.

Depending on your brand of toilet and model, you made need a specific type of flapper. But, of course, you should bring it to the store with you. Instructions for flapper installation vary, so follow the manufacturer’s instructions and ensure the chain is the proper length for full flushes.

 

An Unaligned Float

This is one of the most common causes of a running toilet. A float that’s set too high will make the toilet constantly run. When the float is too high, it makes the toilet fill the tank over the overflow pipe. This means your toilet will run indefinitely, so you need to adjust the float. To adjust the float, push the arm down so the float sits lower. You may need to try a couple of different positions before you find the right one.

 

Adjust The Fill Tube

The fill tube goes into the overflow pipe, but it will make the toilet run if it is constantly submerged. To fix this, you need to adjust the fill tube. If you can’t pull the tube up and out of the overflow water, trim the tube itself so it isn’t submerged anymore.
