My Toilet Won’t Stop Running

toilet tankHave you ever received your water bill, only to be shocked by how high it is? While there are certainly many possible explanations for an unusually high water bill, one common problem that you may experience is a toilet that won’t stop running. Sometimes, this running happens nearly silently, so you aren’t even aware it’s happening until you receive your high water bill. Fortunately, if you know what problems to look for, this is typically an easy fix.


The Float Floats

One possible explanation for a constantly running toilet is a fill float that’s set too high. Your fill valve in your toilet utilizes a float to determine when the tank is full and, therefore, when to shut off. If this float is allowed to rise too high, too much water will enter the tank until it begins spilling down the overflow tube. As the fill valve senses water leaving the tank, it will continue to allow more water in, thus keeping the cycle going and your water bill increasing. In this instance, all you would need to do is adjust the fill float slightly lower until the fill valve shuts off after you flush.

Hang in Your Chain

Another important component of your toilet’s flush system is the flapper. This is a rubber component that lifts up when you pull the handle to allow water from the tank to enter the bowl. If the chain on the flapper is too short, this can create too much tension on the flapper, meaning it will sit just barely above the flapper valve. Since water can find even the smallest spaces, it will run out this tiny opening, causing a never-ending cycle of tank filling.


No More Flapping

Another problem that you could experience with your flapper is that it simply gets worn out. Over time, especially if you have hard water, the minerals in the water can begin to break down the rubber, making it less flexible. Since flexible rubber is required for a tight seal over the flapper valve, rigid rubber will begin to allow water into the tank, causing constant filling. This component is simple and easy to replace, just make sure you select a flapper which is designed for the year that your toilet was manufactured.


Flush Valve Vexing

Another rubber component in your tank which may lead to constant filling is the rubber gasket seated at the top of the fill valve. This component keeps the valve from opening except when the tank is flushing, meaning if it’s worn out, the valve will begin to run more and more until it’s constantly running. You don’t need to worry about your tank overfilling thanks to your overflow pipe, but you do need to worry about a sky-high water bill. These gaskets literally cost cents to replace and the procedure to replace them is extremely simple.


Other Problems

If you’ve taken a close look at all the components in your toilet’s tank and they all seem to be operating correctly, there may be a more serious issue you’ll need to deal with. It’s a good idea to call in a professional to prevent a large water leak that could damage your home. Anything from a crack in your toilet to a damaged wax seal at the base of the toilet could be at fault, and proper diagnosis and repair is crucial to ensuring the water stays where it’s supposed to be.
