A toilet with a button flush is handy and simple to use. However, even such a handy thing can have issues at times. As such, a running toilet problem isn’t uncommon at all. Fortunately, you can fix this issue by yourself with just a little effort and knowledge. All you need to do now is to read the information below and find the solution you need.

How To Fix A Running Toilet With A Button Flush

1. Check The Outlet

In order to determine whether or not a running toilet problem is caused by a flush valve, check if there’s water in an overflow pipe till the top. If not, then the problem is caused by a flush valve, also known as an outlet.

Flush a toilet so you can empty a flush tank and then remove a flush valve.

Be careful while removing it to prevent damaging a flush system. Try slightly twisting it on the right and left side to make it pop out quickly. Try both sides carefully but firmly until a flush gets released from the connection point. Just pay attention to the sound of the click; hearing it means that the flush got released from the connection point.

After removing an outlet, you’ll notice that an overflow pipe is properly connected to a connection point of a flush valve. Furthermore, the thing preventing water from draining was the rubber seal down a flush valve. However, a seal must be undamaged to properly hold water back in a flush tank. So try checking whether it is still usable.

If you notice even a slight damage, you’ll know why a toilet keeps running continuously. In this case, you’ll need to replace a rubber seal. If it is an emergency, remove a seal and try flipping it and using it. In other words, you can use the unused side of a seal. This can work in the majority of cases but can’t be a complete solution. However, it’ll still work temporarily until you get a new rubber seal.

But what if a rubber seal isn’t damaged? In such a case, the problem can be caused by a disc going up and down with a push on a flush button. The disc needs to properly sit on and fit a connection point to ensure smooth movement. It has to be sealed as well. If that’s not the case, you’ll need to replace an entire flush valve.

If neither a rubber seal nor a disc is causing the problem, check the fill or inlet valve. Pop in a flush valve back in its connection point. Then start working on a fill valve. However, before installing an outlet back, ensure to thoroughly clean around a connection point. There are certain cases where a filthy connection point causes the running toilet because of a failure to seal.

2. The Inlet

When the issue isn’t caused by a flush valve, the culprit has to be a fill valve. First, try checking the top section of an inlet. Keep in mind that you’ll need to remove an entire fill valve. To do this, try unscrewing the nuts with the wrench beneath a tank. But before doing so, ensure a tank doesn’t have water in it.

After unscrewing the nuts, you’ll see a fill valve coming out of its slot. Then you can remove the top cap for exposing the inlet’s top section. Keep turning it right and left. It can be tight and stuck, so be careful as you are removing it. You can unscrew a float cup adjustment screw to make your work significantly easier. You’ll have a much better hold on a top section, which will make rotating and removing it easier.

After removing the fill valve’s top section, flip it and take a look inside. You’ll see the round disc that has a thin sharp pointer. Try using forceps to easily remove a disc from a slot. After removing a disc, you’ll notice a washer or several washers in the fill valve’s top section. It’ll most likely be the damaged large washer that is causing the running toilet.

You can then replace a washer or an entire inlet to solve the running toilet issue.

If you’re replacing a washer rather than an entire fill valve, ensure you thoroughly wash the top section so you can remove debris from the section and then reinstall it.

3. Overflow Pipe

If there’s water in an overflow pipe, it indicates that the tank is filling too much and too fast because a fill valve isn’t adjusted correctly.

An overflow pipe takes the extra water inside it and then releases it into a toilet bowl as a way to prevent flooding water through a lid.

You’ll need to adjust a float cup for controlling a cistern’s water filling speed. Adjust a cup, fill a tank and then flush a tank to achieve the proper adjustment. Moreover, work on a water connection so you can lessen a water-filling pace.
