Buying Guide for Best Toilet Flappers

Buying the best toilet flapper may seem like a drag for most people. We are talking about a small, almost irrelevant piece, most of us take for granted. But a good, high-quality toilet flapper can make all the difference in the world. For instance, if you have a good toilet flapper the dissolving toilet paper won’t get clogged while flushing.

It would be ideal to purchase the right one right from the beginning. But, regardless whether you are at your first purchase or not, you need to know what to look for. And several criteria stand out as the most important:

  • Material durability – The stronger and more qualitative the material is, the longer the lifespan of your flappers
  • Special features – Here, I am referring to things like anti-leakage mechanism, anti-corrosive material and antiseptic properties
  • Easy to install – Nobody has time to try and figure out how to install a toilet flapper
  • Modern design – Although not as important, it is a feature to keep in mind nonetheless

What I am trying to point out here is that toilet flappers are more important than the majority of consumers tend to think. They play a crucial role in maintaining your toilet functionality. And if you want to change yours, make sure you have your eyes on a grade ‘A’ one.

 

What Causes the Toilet Flapper to Stay Open?

In most of the cases, toilet flappers will function just as intended. However, problems may hit you every now and then. It may not close all the way, or maybe it won’t close at all.

This is probably the most common cause for toilet dysfunctionality – the toilet flappers malfunctioning. And, although we are talking about such a small and apparently insignificant piece, the outcome can be quite annoying including a higher bill for water expenditure. And this problem can’t be solved even with the best wax free toilet seal.

But what causes the flappers to stay open? And what can you do about it?

More often than not, the problem is with the adjustment. Flappers are adjustable and setting them for the wrong value can cause problems. So, the best way to solve the problem is to readjust the flapper, if needed.

Another reason may be the fact that the flapper is either broken or loosen up. In both of these cases, you need to acquire a new one. Flappers are inexpensive pieces of equipment, but as you can see, their impact is quite worthy of mentioning. Simply replace your flapper and bring your toilet in its impeccable shape one again.

 

How to Replace Your Toilet Flapper

Replacing the toilet flapper is not such a routine job to do because flappers don’t usually break too often. But one that has to be done when the time comes.

And, despite the installation process being fairly easy, it doesn’t hurt to write it down here for posterity:

  • Cut the water to the toilet – You can do that by using the valve that delivers water to the tank. It is usually located on the wall, right beneath it.
  • Remove the failing flapper – It should have a clip so that you can undue and release the piece.
  • Put the next one in place – It should be easy to mount, as all you will be doing is reverse the procedure you applied when eliminating the old one.
  • Turn back the water stream – After the tank is connected to the water stream once again, flush your toilet several times and make sure there are no leaks.

As you can see, nothing too fancy about it. It should take you no more than 5 minutes.

 

How to Fix a Leaky Toilet Flapper

Fixing your toilet flapper is embarrassingly easy. The real problem is figuring out what the fault is. There are, overall, 2 main causes for your flapper to leak:

  • The wrong model of flapper being used, which can translate into uneven matching or straight out incompatibility
  • Corrosion, causing the flapper to either crack, break completely or develop jaded margins

So, in these cases, what is the fix? Just like I said, pretty easy – just replace your toilet flapper altogether. Don’t even bother looking for other solutions. Toilet flappers are affordable and a good piece can cover all your problems in an instant.

 

Final Verdict

Most toilet flappers have five or even ten years guarantee and the more modern models are incredibly resilient. Just follow my guide and look for the best piece that fits your needs and you should be good to go.

With so many options to your disposal, finding and getting the right toilet flapper should be a piece of cake.

There are a lot of toilet flappers on the market nowadays. But, in most cases, it is difficult to realize the key differences between them. And knowing which is better ultimately translates in you saving a lot of money and time.

Toilets don’t break or malfunction too often, but when they do it is likely because of the poor-quality flappers. Save yourself the trouble and get the best toilet flapper money can buy. Take my review as a guide and you should have a pretty solid starting point.
