Quietest Toilet Fill Valves 2021
If you are looking for a fix for the noisy and running toilet in your house, then this kit could be the solution to your problem.
The kit comes with the iconic 400A toilet fill valve from Fluidmaster, which is considered to be one of the most popular valves in the world. The valve comes with an anti-siphon design that prevents any water leaks from the tank.
Included in the kit as well is a sturdy frame flapper. With this, you can align the tank.
The flapper helps to achieve a consistent and powerful flush every single time. It is also quite reliable and is made of corrosion-resistant materials.
The valve is available for use in tanks that hold 3.5 gallons per flush or even larger. The solid frame build makes the kit more durable and you won’t have to keep replacing the valve every so often.
A bonus advantage for this kit is that it is quite easy to install and use.
Within 10 minutes, you can have the valve installed and ready to use. It also comes with a 7-year warranty which is frankly a bonus point on its part.
The Kohler Valve kit is a favorite for many, especially because it is an adjustable valve and is made to be adaptable to all types of toilets.
Just like the Fluidmaster valve above, Kohler is a long-trusted brand and its valves are well known for their durability and effective performance.
The valve is fully adjustable and so is the fluid flow. This makes the system more efficient when it comes to saving water and hence reduce energy bills.
To accommodate standard cleaning requirements, the length of the valve can be adjusted to up to around 13 inches.
Because it is mainly made of high duty plastics, the Kohler valve tends to be more durable than its counterparts.
The refill rate on this valve is quite impressive. Within 40 seconds, the tank can be completely full with significantly less noise made.
This rate is quite high as compared to other valves which makes the waiting time much shorter.
The kit does not come with an instruction’s manual. However, all you need is a few minutes to figure out what goes where and you will have the valve installed in a short while.
Although this kit is a bit pricier than the others on the list, its efficiency makes it worth the price.
The kit comes with a couple of accessories for your toilet tank.
The kit includes a Fluidmaster 400A fill valve, coupling nuts, a lock, a refill tube, and a washer as well.
The valve comes with an anti-siphon feature that helps to reduce leaks as well as prevent contamination. The height can be adjusted to 14 inches to fit the specifications of your toilet.
Unlike standard toilet fill valves, this valve offers a quiet and fast refill. The refill rate is about two times as much as that of other models making the waiting time short.
We especially love the fact that the valve is universal. It is made to fit most of the American Standard toilets and because all the accessories are adjustable, you can get it to fit your toilet tank perfectly.
Given that the valve can handle volumes of up to 7 gallons, it really is the best one out there.
The kit also includes installation instructions that should help you set up the valve in a matter of minutes.
Korky 528T comes with newer and more efficient technology, making it one of the best fill valves there are.
The valve is made to specifically tackle three common toilet fill valves; slow refill, noise and water leaks. It is able to refill the tank at a fast rate and does so while being incredibly silent.
One of the best things about this valve is that the installation is very easy and straightforward.
Thanks to the twist-lock mechanism that the valve uses, no tools are needed during the installation process.
It is also quite impressive how the valve can handle large volumes of water. This feature makes it possible for you to replace the valve while the tank is still intact.
The Korky 528T has a universal design and is fit to work on most types of toilets given that it is easily adjustable.
The valve also comes with a strainer that traps any sediments in the water. This makes the valve more durable.
While the performance on this valve kit is quite commendable, it is mainly considered a selfish design. This is because it was designed with the TOTO flush tank models in mind and will not work for other brands.
However, if your toilet tank is compatible, this valve is quite an asset to have.
It comes with some cool features such as the EcoPower and the Hydrotect that make it eco-friendly.
EcoPower feature offers better hygiene and a hands-off experience while the Hydrotect feature offers self-cleaning and hence great anti-microbial protection.
While it is made for two-piece toilets, it can also be used on one-piece tanks thanks to the adjustment features.
When used on a two-piece toilet, the valve gives you the option of adjusting both the height and the flow rate as well.
To save on electricity, the valve uses the power that is generated from the moving water.
For efficiency, the valve aerates the flow of the water and also has a built-in sensor that prevents the water from running once the tank is full.
The valve comes in three different styles so you can choose one that suits your needs.
These styles are traditional, transitional and contemporary. A manual is included in the kit to make installation easier.

When looking for a toilet fill valve to buy, there are a number of things that you need to consider. Here are a few tips to have in mind before purchasing a valve.
Now that you know what you need to do before purchasing a toilet fill valve, how do you choose the best?
The available valves differ in both size and price. Here are some of the things that you need to check before settling for a particular valve.
Noise
Newer models of toilet valves are much quieter. When purchasing a toilet fill valve, be sure to check the decibel levels.
A noisy valve can be a distraction especially if the toilet is located near the living room.
Compatibility
Given that the toilet valves are available in different sizes, it is possible that you may buy a valve that is not compatible with the system in your toilet.
For this reason, it is important that you take the measurements of the valve hole beforehand.
Refill rate
If the refill rate of the toilet valve is high, it means that you will only wait a short while for the tank to fill up.
Leak-proof seal
Consider getting a toilet fill valve that will allow you to save on the amount of water that you use.
Be sure that the seal on the valve is leak-proof. You can even incorporate some other water-saving features such as a leak detection system and adjustable water volume.
Guide for Replacing the Toilet Fill Valve
Once you have the purchased the valve, you are going to need to replace it. So, how do you go about changing the valve?
Here are some tips to help you with that.
1. Drain the tank
You obviously cannot replace the valve with the tank full of water. Drain the water in the tank and use a sponge to dry it off.
To remove the valve, remove the gasket and loosen the nut underneath. Proceed to clean the sides and remove any debris present.
2. Replace the valve
Take note of how the old valve was placed as your new one will go in the same way.
Direct the valve through the hole and tighten it enough. Tightening too much may end up breaking the tank.
Be sure to check the height of the tube. Allow for at least one inch below the hole where the lever is mounted.
Replace the rubber gasket and use screws to hold it in position. Ensure the screws are tight so as to provide a perfect seal and avoid any leaks.
3. Test for leaks
Once you have successfully installed the valve, flush the toilet a couple of times to ensure that there are no leaks.
In case of any, check all the connections and tighten them.
