Have you ever walked into your bathroom only to find that your toilet is running nonstop? It can be incredibly annoying, and if it’s a problem that keeps happening, you may be frustrated trying to figure out what’s causing it. Luckily, our team at Simpson Plumbing Services has put together this article to help you understand why your toilet might be running nonstop and what steps you can take to fix it according to plumbers.

How does a toilet work?

The answer to this question may seem obvious, but there are a lot of different factors at play when it comes to how your toilet works. Toilet tank fill valves are designed to maintain a certain water level in the tank so that the bowl has enough water to flush properly. If the fill valve is not working correctly, it could be causing your toilet to run nonstop.

There are also a few different flushing mechanisms that toilets use, and each operates slightly differently. Some toilets have a gravity-flush system, which uses gravity and water pressure to force waste down into the sewer line. Other toilets have a pressure-assisted flush system. Which uses a pump to create additional pressure that helps push waste down into the sewer line. If your toilet is equipped with a pressure-assisted flush system, it is possible that the pump is not working correctly. Which could also be causing your toilet to run nonstop.

Common causes of toilet running when not in use

There are a few different reasons why your toilet might keep running nonstop, even when you’re not using it. One common reason is that the water level in the tank might be set too high. If the water level is too high, it can cause the float ball to get stuck in the “up” position, which will cause water to keep running into the bowl.

Another common reason for a toilet to keep running is a problem with the flapper valve. The flapper valve is what allows water to flow from the tank into the bowl when you flush the toilet. If there’s a problem with the flapper valve, it can cause water to leak from the tank into the bowl, which will cause the toilet to keep running.

If your toilet keeps running, it’s best to call a plumber to come to take a look and see what’s going on. They’ll be able to troubleshoot the problem and make any necessary repairs.

Troubleshooting for common problems

If your toilet is running nonstop, it’s likely due to a problem with the fill valve. The fill valve is the mechanism that controls the flow of water into the toilet tank. It’s usually located behind the toilet, near the floor.

First, check to see if the fill valve is properly seated in its housing. If it’s not, tighten the screws that hold it in place. If that doesn’t fix the problem, try adjusting the float arm. The float arm is attached to the fill valve and controls how much water flows into the tank.

If adjusting the float arm doesn’t stop the water from running, there may be a problem with the flapper or flush valve. The flapper is a rubber seal that covers the flush valve opening. Over time, it can become damaged or warped, which can cause it to leak. The flush valve is located at the bottom of the tank and controls how much water is released when you flush the toilet.

If you’re still having trouble, give us a call and we’ll be happy to help troubleshoot your issue.

How can I prevent this from happening again?

If you’re noticing that your toilet keeps running nonstop, a few things could be causing the issue. First, check to see if the water level in the tank is too low. If it is, adjust the float ball or fill valve so that the water level is higher. Next, check to see if the flapper or flush valve needs to be replaced. This is usually the case if your toilet is older. Finally, make sure that there isn’t any debris blocking the hole where the water goes into the bowl – this can cause a leak. If you’re still having issues, it’s best to visit Simpson Plumbing Services to take a look.


Keeping your toilet running nonstop can be a frustrating and expensive problem. Fortunately, you can take a few simple steps to get it back in working order. Start by taking off the lid of the tank and checking for any parts that may need replacing or adjusting. Cleaning out the sediment buildup in the tank is also helpful for restoring its functionality. If these DIY fixes don’t help, then it might be time to call a plumber. So they can diagnose what’s wrong with your toilet and make sure it gets fixed correctly!
