Introduction

Learn the simple four-step strategy that solves 95 percent of toilet flush problems. Stop water from constantly running, give a wimpy flush a boost, and solve other common problems quickly and easily.

The basics of how a toilet works haven’t changed much in the last 80+ years. After a flush, water fills the toilet tank, lifting a float that shuts off the water when it reaches a certain level. A lever still opens a flapper to cause the flush, falling back into place when the water level drops.

So, it should come as no surprise that we still have to deal with the same common flush problems from time to time. Sometimes the flush isn’t powerful enough, the toilet keeps running, and or the bowl doesn’t refill.

What causes a running toilet?

When water escapes from the toilet tank or a component inside the toilet is leaking, the toilet will continue to run. Generally, this is caused by a leaking flapper, a defective fill valve, or an incorrectly sized overflow pipe. This article will walk you through the solutions to each of these issues, which are not only simple to apply but will also result in immediate savings on your next water bill.

The good news is that most of these problems are easy to fix, without having to replace your toilet. You can complete the first three steps in five minutes. That’ll solve most problems. The fourth step is usually easy too, but not always. More on this later. These steps work for most toilets but not for pressure-assist models. Here’s what to do if your toilet won’t stop running.
