Have you ever heard a constant trickling sound even when no one is using the bathroom? Do you sometimes hear the running water even when the toilet is not in use? If so, then you’re dealing with the common household issue of a running toilet. While it may seem like a minor problem, a running toilet can not only waste a significant amount of water but can also lead to high water bills. Fortunately, fixing a running toilet is easier than you think. In this blog post, we’ll go over some of the common reasons why a toilet runs and what you can do about it.

Check the Flapper

The flapper is the rubber seal that opens and closes to release water when the toilet is being flushed. When it’s not working properly, water can continue to run even when the toilet is not in use. The best way to check if the flapper is the issue is to add some food coloring in the tank and wait for approximately 15-20 minutes. If the water in the bowl turns the same color as the food coloring, then the flapper needs to be replaced.

Adjust the Float

The float is the mechanism that controls the water level in the toilet tank. If it’s too high, it can cause water to run continuously, even when it’s not needed. You can easily adjust the float by bending the metal rod holding the float ball down or you can simply adjust the screw located at the top of the float.

Replace the Fill Valve

If adjusting the float doesn’t solve the problem and the problem continues, your fill valve may be damaged and needs to be replaced.

Clean the Flush Valve

Oftentimes, the problem can be resolved by simply cleaning the flush valve. Mineral buildup can cause the valve to remain open while also preventing the flapper from properly sealing the tank. You can clean the flush valve with white vinegar on a regular basis.

Call in a Professional

If these DIY fixes don’t work for you, it may be time to call in a professional plumber. They can easily diagnose the issue and fix it in no time.


A running toilet is not only an inconvenience but can also be costly. Luckily, with a little knowledge and effort, you can easily fix the problem yourself. By checking the flapper, adjusting the float, cleaning the flush valve, and replacing the fill valve, you can get your toilet back to working order in no time. If these solutions don’t work, don’t hesitate to call in a professional for assistance. Remember, fixing a running toilet may seem daunting at first, but with a little guidance, you can do it yourself!
