A running toilet is probably one of the worst among all the different problems you may face as a homeowner.

Not only does it waste a lot of water, but it also poses a serious health risk. Thus, it is in your best interests to fix it as soon as possible.

Now, if you are not an experienced DIYer, the very thought of stopping a running toilet by yourself may give you the willies. But we suggest you stop worrying because it is not as difficult as you think.

So, the question automatically arises - how to stop a running toilet easily? That’s what we’re doing to discuss in this brief guide. And we hope that after reading through this article, you’ll be more than ready to fix a running toilet the DIY way.

Let’s get going, then!

Causes Of A Running Toilet

Before we fix the problem, it is important to diagnose it properly. In this section, we have discussed some of the most common causes of a running toilet. Once you have determined the cause, fixing it becomes relatively easy.

So, let’s look at some of the most common causes of a leaky toilet.

1. Faulty Or Damaged Valves

A typical toilet consists of different types of valves that have distinct functions. You have the fill valve, which helps fill up the flush tank with water. Then there is the flush valve, which drains the stored water when you flush. And the overflow valve maintains the water level and pressure in the flush tank.

If any of these valves were damaged or ruptured, the water would start leaking out of your toilet. Therefore, to determine which valve has been damaged, you will need to remove the lid over the flush and check for damages.

2. Ruptured Fill Tube

As you can guess from the name, the fill tube helps to fill up the toilet tank and is controlled by the fill valve. If it becomes ruptured, then some of the water will start leaking outside the toilet.

To check if your fill tube is ruptured, open the lid and empty the tank. If you see water leaking out of it while the tank is being filled, you’ll know it is ruptured.

3. Damaged Flapper

The flapper is the mechanism that controls the flow of water from the flush into the toilet bowl. It consists of two components - a sealing gasket and a chain, which works in conjunction with the flush valve to supply water to the toilet bowl.

So, if the chain or sealing gasket breaks, the water will start leaking out of the flush tank. Fortunately, it is easy to diagnose if the flapper chain is broken. Simply take off the lid of the flush to check if it is intact.

For the gasket, you can try to put some pressure on it to see if the leakage stops. If it does, then the gasket is damaged and needs replacement.

4. Malfunctioning Toilet Handle

The toilet handle is connected to the flush valve and flapper via an elongated rod-like mechanism. So, if the handle malfunctions, the flushing mechanism will not work properly, and the water will eventually start leaking out of your toilet.

You can easily tell if the handle is malfunctioning since it will cause problems whenever you try to flush. But if you want to double-check, you can remove the lid and check the handle from the inside.

How To Stop A Running Toilet?

Now that you know the primary reason behind a running toilet, it’s time to fix the issue. For this, you need to follow a systematic process, as we have described below.

Step 1: Turn Off The Water Supply

Before you get started, you must turn off the water supply to your toilet to prevent wastage. Besides, it will make your work much easier without the excess water splashing everywhere.

Step 2: Remove The Upper Lid Of The Toilet

This step is self-explanatory and requires you to remove the upper lid to access the toilet inside. You need to dislodge the top by pulling on it gently and carefully. If there are some latching mechanisms, you will need to loosen them to remove the cover safely.

Step 3: Flush Out The Tank

Once you have turned off the water supply and removed the lid, you must flush out the water from the tank. All you need to do here is press the flush button!

However, if the handle is malfunctioning, then you will need to siphon the water out using a pipe. In any case, once the water has been drained out, proceed to the next step.

Step 4: Fix The Leak

This is the most important step, and it may vary slightly based on the cause of the leak. If the cause of the leak is a ruptured fill tube, damaged valve or a broken handle, then you will need to replace them with a new one.

You’ll need to dismantle the existing part using pliers and a wrench. Subsequently, you will need to install the new one and secure it.

In case of a broken flapper chain, you will need to remove the old chain and replace it with a new one. The same goes for the sealing gasket; after you have replaced it, make sure to tighten it.

Step 5: Put The Toilet Lid Back In Place

After you have fixed the issue, it is time to put the lid back and secure its latches, if there are any. In this regard, we suggest you check if all the parts are working as expected. Once everything is in order, secure the lid, and you’ll be done.
