AvatarByLiana Farrell Toilet Queries

Do you hear a dripping sound coming from your bathroom? If so, it could be a sign that your toilet is leaking. A leaky toilet can waste hundreds of gallons of water each year, which can lead to higher water bills and increased environmental impact. Luckily, checking to see if your toilet is leaking is a quick and easy process. In this article, we will walk you through the steps on how to check if a toilet is leaking, so you can take action to stop the waste and save money.

How to Check If a Toilet Is Leaking

1. Look for signs of water around the base of the toilet. If you see water pooling around the base of the toilet, it’s a good indication that there is a leak.
2. Turn off the water supply to the toilet. The water supply valve is usually located on the back of the toilet tank. Turn the valve clockwise until it is completely closed.
3. Flush the toilet. After you have turned off the water supply, flush the toilet. If the toilet continues to run after it has been flushed, it means that there is a leak in the flush valve.
4. Check the flapper. The flapper is a rubber disk that sits in the bottom of the toilet tank. It is responsible for stopping the flow of water when the toilet is flushed. To check the flapper, lift up the toilet tank lid and look at the flapper. If the flapper is torn or damaged, it will need to be replaced.
5. Check the water level in the toilet tank. The water level in the toilet tank should be about 1 inch below the top of the overflow tube. If the water level is too high, it can cause the toilet to overflow. To adjust the water level, turn the float arm clockwise to raise the water level or counterclockwise to lower the water level.

By following these steps, you can quickly and easily check if your toilet is leaking. If you find that your toilet is leaking, you can take steps to fix the leak and stop the waste.
