Buying Guide of Toilet Fill Valves

 

There are, overall, 3 problems you have to deal with, as a toilet owner:

  • Leaky valves, causing unnecessary water consumption
  • Loud water filling
  • Low water volume being pumped through the valves

Each of these problems can lead to quite a few problems, including a larger money drain. Another important aspect could be the fact of poor valve design. Since these are mobile parts, it is crucial for them to be constructed from solid, quality material.

What can you do to avoid and overcome these problems? Simply put – Look for upgrades. There are always better versions of filling valves you can find, but it is important to know the criteria by which to choose them. And the most important are:

  • Material durability

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?

 

How to Fix a Toilet Flush Valve

 

 

But what can you do when replacing isn’t necessary? The flush valve can malfunction for a wide variety of reasons, including breakage or corrosion. Both of which require replacing the piece.

However, in some cases, something else might be at play. The valve can fail to close completely because of the dirt accumulating around the drain over time. When that happens, the best thing to do is to simply clean it thoroughly. This can be achieved by following several simple steps:

  • Empty the tank completely and dry it using a sponge or a rug
  • Remove the drain valve flapper
  • Clean the valve seat of any debris or accumulating dirt
  • Replace or add a sealant ring onto the drain seat
  • Put everything back together and test the mechanism for leakage and efficiency

Obviously, this fix only works when the problem with your flush valve is not major. If it is, all you can do is to replace it completely. Fortunately for you, dirt is the most common leakage or clogging problem, which means cleaning the valve works great.

 

What are the Benefits of Best Toilet Fill Valve

 

The main issue here is that most people won’t even realize the importance of good toilet fill valves. Since they don’t usually spend too much time in the bathroom, it won’t hit them until problems start appearing. In reality, having an optimum, high-quality toilet valve can make all the difference in the world.

The best toilet fill valve will deliver the following benefits:

  • Put an end to toilet leakage problems
  • Lower the amount of water being wasted
  • Allow you to adjust its height and water volume being used
  • Quieter than its alternatives
  • Fills your tank faster

Simply by keeping these in mind and you can definitely see the plusses. And, since not all toilet valves come with the same features, these will also serve as a guide on how to find the best one for you. The most advanced models will even come with built-in sensors, letting you know of any water leaks present.

It is not a matter of “Should I get one?”, but one of “Which should I buy?”

 

How to Replace the Toilet Fill Valve

 

 

Replacing a toilet fill valve is one of those things that everybody needs to learn how to do themselves. It is not a difficult process, but rather a complex one since there are a few steps to follow. These include:

  • Shutting off the water by turning the valve clockwise and removing the lid from the tank
  • Drain the water from the tank completely
  • Remove the fill valve by loosening the lock nut, located beneath the tank, that keeps it in place
  • Prepare the new one, including attaching the rubber washer and adjusting the height according to your needs
  • Insert it in position and lock it with the help of the embedded mechanism
  • Attach the refill tube to the overflow pipe and the water supply tube to the tank
