Spotting a Malfunctioning Toilet Flush Valve

The flush valve on your toilet is made up of several components. The first is an overflow tube, which is responsible for ensuring that water flows harmlessly into the toilet in the event that the inlet valve malfunctions and continues allowing water into the cistern. The second is a hole at the base of the cistern, through which water can flow to reach the toilet bowl. The third is a flapper, a rubber mechanism that covers the hole when the cistern tank is full, creating a seal to prevent water from draining into the toilet bowl when it isn’t needed. These components work in concert with the flush lever or button on your toilet, to activate when flushing is necessary.

If part of your valve system is broken, the toilet will not be able to flush properly. There are a few issues to look for when trying to determine if you need a flush valve replacement—the most common a leaking toilet cistern. The water won’t be leaking onto the floor, so you might not notice it right away. However, you will hear water leaking, and it might even sound like your toilet is running all the time. The issue here is that the rubber flapper in your valve is struggling to form a seal with the base of the cistern. As a result, it’s consistently letting water flow into the toilet bowl. This issue can cost big money in the form of wasted water down the drain. You might also notice an issue where your toilet bowl is no longer filling with water to a consistent level. This issue is linked to the overflow tube. Either problem may require a replacement of the valve system.
