How to Check Toilet for Leaks: 6 Tips for Homeowners

No matter if you live in an apartment or a house, you know all too well about how important your machines are. From the sink to the toilet, all need to be in good working condition at all times. Unfortunately, that is bound to change down the line.

This largely comes down to either wear and tear, or due to external factors such as inclement weather. In regards to the toilet, there may be various factors that contribute to an unwarranted leak. Thankfully, fixing it can be just as easy as finding the sources of the potential leak.

Generally speaking, if any of your home devices or apparatuses make loud noises, it may be cause for concern. The same can be said for your toilet, even if it is a rather uncommon source of leakage. Noise that emanates from your toilet should be an immediate red flag, and requires your swift attention.

As for the noise itself, the toilet will give off a very noticeable, and audible, sound. This can be related to a running noise, which could get louder if not taken care of sooner. Should the noise persist, a leak is bound to happen in some extent. You should take of this as soon as possible, or call in a plumber if you can.

Use the following 6 easy tips on how to check toilet for leaks:

1. Shut Water Off

When you check the toilet for leaks, make sure you turn the water off. One of the more drastic ways to check for a toilet leak has to do with shutting off your water. Normally, you wouldn’t want to attempt this during the day. However, if you think the issue is minor, shut the water off before you go to bed at night.

The following day, check out the water within the tank of the toilet. A secure toilet will still have all the water inside for the most part. If there is virtually no water inside when you check it out, you may have a problem. Less than an inch of water inside the tank indicates that a leak may be present.

2. Food Colouring

Using food colouring to check for a toilet leak is one of the most common methods to implement. To begin the process, remove the tank lid from the top of the toilet. After this is done, you will want to flush the toilet as you normally would. Once this step has been completed, put four or five drops of food colouring into the tank.

Make sure that you use a dark colour for the best results. The next step involves placing the tank lid back on, and then waiting it out. Once twenty minutes have elapsed, take a look at the toilet bowl. If the water inside has changed its colour, then there is definitely a leak present!

3. Flapper Test

Another easy technique used to check for leaks in your toilet involves the machine’s flapper. The flapper can be seen as the rounded rubber seal that rests at the bottom of the toilet tank. By design, the flapper is intended to prevent the water inside of the tank from entering the bowl.

Should you suspect a leak that has to do with the flapper, turn off the water supply valve near the toilet. Wait about fifteen minutes, and then check the water levels in the tank. If there is a noticeable decrease, the issue may have to do with the flapper itself. As a result, the flapper may be the source of the leak taking place.

4. Water Level Test

There are several mini tests that could be conducted on the parts inside the toilet, when trying to find a leak source. For example, you could check the float, which is a part that tells the connected inlet valve when to shut off the water valve.

If the water is continually flowing past the connected overflow tube, then a leak may be occurring nearby. Usually, if water levels inside the toilet tank look distorted, it may be time to do further investigation.

5. Trickle Down Sign

Another easy, albeit unconventional, way to locate a leak within your toilet has to do with the toilet bowl itself. If water is trickling down the inside of the bowl when it hasn’t been flushed, there may be a leak occurring.

6. Call a Plumber

If all else fails, and none of the tests have worked as you intended them to, you may have to contact a third party. A professional plumber will be able to diagnose the issue for you, so that your toilet returns to working condition!

A good toilet shouldn’t be affected by negative factors for the most part. However, there may be subtle signs that indicate that a leak may be happening. Take the time to inspect these carefully, before taking the necessary action!
