How to Stop a Toilet That is Running Constantly

A constantly running toilet is not only annoying, but it can also waste a lot of water and increase your water bill. This issue is often caused by a faulty flapper or fill valve, which are both inexpensive and easy to replace. However, if you are not comfortable with DIY plumbing, it’s best to call a professional for help.

Diagnosing the Problem

Before attempting to fix a running toilet, it is important to understand the root of the problem. The first step is to remove the lid from the toilet tank and inspect the inside components. If you see water constantly filling up in the overflow tube or if there are bubbles coming from under the flapper, then your fill valve may be faulty. On the other hand, if the water level in the tank is consistently low, then there may be an issue with the flapper.

Fixing a Faulty Flapper

If the issue lies with the flapper, start by turning off the water supply to your toilet. This can usually be done by turning the shut-off valve located behind or near your toilet clockwise. Once the water is turned off, flush the toilet to drain out any remaining water in the tank. Next, remove the old flapper and replace it with a new one of the same size and shape. Make sure to follow the manufacturer’s instructions for installation. Finally, turn the water supply back on and adjust the chain length if necessary.

Replacing a Faulty Fill Valve

If the problem is with the fill valve, start by turning off the water supply to your toilet. Flush the toilet to drain out the remaining water in the tank and use a sponge or towel to soak up any excess water left inside. Next, disconnect the refill tube from the top of the fill valve and unscrew it from the bottom of the tank. Remove the old fill valve and replace it with a new one following the manufacturer’s instructions. Finally, reconnect the refill tube and turn the water supply back on.

Other Possible Causes

If replacing the flapper or fill valve does not solve your problem, there may be other issues causing your toilet to run constantly. One possible cause is a leak in the fill valve. To check for this, add some food coloring to the water in the tank and wait for a few minutes. If the water in your toilet bowl has changed color, then you have a leak and will need to replace the fill valve.

A constantly running toilet can be a frustrating issue to deal with, but it is usually an easy fix. By understanding how your toilet works and following these simple steps, you can save water and money by stopping your toilet from running constantly. So, don’t hesitate to seek help when needed. However, if the issue persists or if you are not comfortable with DIY plumbing, it’s best to call a professional for help. By taking care of your toilet and addressing any issues promptly, you can save water and money in the long run. Be proactive and keep an eye out for any signs of a running toilet to avoid any potential problems.
