Types of Toilet Fills/Flush Valves
There are different types of toilet fills. Here are the most popular ones.
Diaphragm Valve
This style of fill valves is quite traditional, yet we can still see many brands opting for it. In previous times, these were manufactured with plastic, but today’s contemporary ones are built with brass. The diaphragm design is mostly confused with the ballcock ones, as some of their components including balls and float arms resemble a lot. But these designs aren’t as similar as they seem. Equipped with the anti-siphoning feature, this kind of fill valve consists of a lid that opens or shuts while the movement of water is being regulated or changed.
One minor inconvenience is the not-so-easy restoration process. Which is why most users have to go with changing it altogether with a new diaphragm valve. Luckily, they are not very expensive so purchasing them occasionally will not be a burden on your pocket.
Plunger or ballcock valve
This one is also an older design yet is still used. They commonly have a brass build and come with a low discharge pipe as well as a connected float ball. This floating ball shuts or opens the stem of this fill valve, according to the extent of water that is inside the tank. The plunger also comprises a washer made of rubber which if ruined, cannot be repaired. Any big fault in the ballcock valve will most likely lead to a replacement since this valve does not go along with contemporary methods of plumbing that are used today.
Cupless or Floatless ballcock valve
Also famous by the name of ‘cupless’ fill valve, this design is equipped with the power of detecting the pressure applied by water and identifying the height where the water reaches, merely from the base of the tank, thanks to the diaphragm that comes along with it. It doesn’t use a cup or ball for this purpose. This flush valve is also made in the anti-siphoning style yet it is considered to be a much modern design in that category. These cupless valves can easily function even when they are submerged in water. Adjusting these cupless valves is not very difficult too. You can do so by simply rotating the screw that is positioned on the head of the valve.
Since these were especially used for toilets that had tanks at lower levels in the past, these floatless ballcock valves are not the best option for today’s contemporary toilets.
Container or Floating cup valve
This cup style valves are one the most popular and recent designs of toilet fill valves that are manufactured today. Most of the toilets we get in the market nowadays are likely to be equipped with the container fill valves. The most prominent feature of this type is the ability to modify and adjust the size of this valve according to our requirements. This makes it universally suitable for numerous toilets. If you can get it within the lengths of 7 to 13 inches, then it would be perfect for any of your toilets.
The water level is managed by a floating cup as the name suggests. These cup valves are extremely simple to use, fit, and manage. So most people usually replace their older designs with this style.
How to find the best toilet fill valve for you
We are aware that deciding upon a fill valve for your toilet can be bothersome, and time-taking. So what should you do?
Always go for well-trusted brands
We suggest that you should avoid buying toilet valves from manufacturers that aren’t popular. Kohler, Fluidmaster, TOTO, and American Standard are some of the most reputed companies in the world of plumbing and toilet products.
Read reviews and check ratings
Search the web to get acquainted with the available options in the market, and find their ratings. Along with others, we recommend you thoroughly read our reviews included on this page to make a wise and timely decision.
Check warranty
Always make sure the manufacturer is offering a longer period of warranty for your choice of product. More than 3 years is always a good deal.
Adjustable height
Valves with this feature are known as universal since they can fit almost all toilet tanks so you don’t have to spend ages over finding the perfect sized option. They can be easily customized to your needs.
Quiet fill
It should be almost noiseless during the water refills since no one likes to use a toilet where there isn’t a quiet environment.
Simple installation method
Your purchase should come with an easy-to-understand user manual with complete instructions so that no expertise is needed to fit it.
Water Conservation
It is our responsibility to avoid wastage of Earth’s precious natural resources. Therefore, we can’t stress enough how important it is to always buy toilet valves that save water.
How to check the compatibility of the toilet valve
Before buying a fill valve you must ensure that it’s the perfect size for your toilet tank. You should know that valves are of various kinds and sizes. It is necessary that you carefully read the product details before making a purchase. It is sensible if you go with the one that is similar in design and proportions to the one that you are planning to change.
Measuring the height and width of the water container is also recommended so you can fit and install your new valve later without any issues. Adjustable valves always come in handy since they fit into almost every kind of toilet.
Which material is best for the toilet fill valve
Although a few components can be constructed with metal, we suggest that you do not go with fill valves that are entirely made of metal since they are prone to rust and water damage. The perfect materials in our opinion are plastic, rubber, and ABS substances since they are resilient and enhance the endurance and life of the product.
Conclusion
It is a smart habit to keep a sharp eye on your toilet fill valve since they are vulnerable to faults and damage. If you find drips or leaks, or it has started making annoying noises, then it is time to check the fill valve of your toilet. This is important if you want a smooth and hassle-free experience.
