  • Clean the valve seat of any debris or accumulating dirt

How Does a Toilet Flush Valve Work?

If you think most people have no idea how a toilet flush valve works, you got it just right. And, if you think about it, why would they? The problem with toilets is that they don’t usually break. I know, the word “problem” may seem a bit weird in this context, but hear me out.

If your toilet never breaks, you will never going to have to fix it. This means you will have no idea how it functions. And having somewhat of a grasp regarding its functionality is crucial. Because, eventually, your toilet valve will break too.

The flush-and-refill mechanism is an easy to understand concept:

  • The toilet tank is capable of holding around 2 gallons of water
  • The flush valve is put in place to hold and release that water when needed
  • Once the tank has been emptied, the flush valve moves back into its initial position, sealing the drain again
  • The filler valve is a second security mechanism, making sure the tank doesn’t overflow and floods the bathroom
  • The filler valve functions based on the filler float that, when reaching a certain height thanks to water level increasing, causes the filler valve to seal the drain

Pretty straightforward, right?


Final Thoughts

From my point of view, the best toilet flush valve is one that comes with several distinct features:

  • Impressive design
  • Outstanding material quality
  • Durability
  • Solid construction, according to the latest standards
  • Efficiency in delivering as expected
  • Long-lasting results

I advise you never to settle for any less than this. A top-notch flush valve can solve a lot of your toilet problems, most of which can cause you to lose money regularly. It is not too difficult to find good pieces for affordable prices. All that matters it’s for you to know what you are looking for.
