Is your toilet leaky, constantly running, or too noisy to flush at night without waking up the entire house? If so, it’s probably time to chip in for a replacement valve. Though it’s not the most exciting purchase, a durable refill valve can cut down on water bills while silently refilling the tank without any hassle.

To put it simply, a toilet valve is found inside the water reservoir of your toilet. It is meant to get your toilet to refill to the proper level after flushing.

How to Choose the Best Toilet Fill Valve

Thankfully, there are many distinct, yet competent brands of toilet refill valves that are durable, easy to install, and extremely reliable even after years of daily flushes. Modern plumbing is truly a miracle, isn’t it? Don’t quote me on it, but there’s a good reason why most sociologists say that good plumbing has saved more lives than decades of medical advancements.

Before you go out and buy any refill valve, you should know that there are different models optimized for specific brands of toilets. Choosing the wrong valve will result in slow and noisy refills, in addition to raising your monthly expenses.

Depending on the make and model of your toilet, you may be better suited for a specific type of valve over other types.

In general, you should always opt to buy a replacement piece from the manufacturer of your toilet. Though universal valves are handy, customers often complain that they are trickier to install correctly and may degrade after only a few years.

If you aren’t sure of the model of your toilet, make sure to look at the valve’s manufacturer specifications to see if it will align with the type of toilet that you own. Common code numbers include “400A” or a series of letters and numbers printed on the side of the refill valve. Typically, adjustable toilet valves that lengthen from a range of 7 inches to 14 inches will fit almost any toilet make and model.

Review of the Quietest Toilet Fill Valves of 2020

1. Fluidmaster 400CRP14 Universal Toilet Fill Valve

Sale
Fluidmaster 400CRP14 Universal Toilet Fill Valve and Flapper Repair Kit, for 2-Inch Flush Valve Toilets
  • Features the proven 400A anti-siphon toilet fill valve
  • High Quality and durable toilet fill valve

The Fluidmaster is an easy to install, universal toilet fill valve that fits most toilet models. The 400A toilet fill valve easily adjusts to sizes 9 inches to 14 inches, while the 501 flapper can fit 2 inch flush valve toilets.

If you need to replace damaged fill valves and leaky flappers, look no further than the Fluidmaster. Through the valve’s unique design, your toilet’s flush and fill performance can be optimized to work both quietly and quickly. As soon as the tank is filled to the proper level, the valve works to stop the flow of water silently.

The entire kit comes with a solid frame flapper that aligns with the tank in order to provide the most powerful and expedient flush possible. It’s easy to use, last for several years, and works in any toilet that flushes 3.5 gallons per flush or more.

In fact, it only takes ten minutes or less to get the flapper and valve fully installed. The simple design helps to eliminate old brackets, wire lifts, and automatically assumes proper alignment when placed in the toilet tank.

Customers can rest assured knowing that the Fluidmaster brand has been in business since 1957. In fact, Fluidmaster is considered the most popular toilet repair brand in the world in terms of gross sales volume over the past ten years.

2. Kohler Genuine Part Gp1138930 Silent Fill Toilet Valve Kit

Sale
Kohler Genuine Part Gp1138930 Silent Fill Toilet Fill Valve Kit, 12.5″ x 3.5″ x 3″
  • Kohler genuine part
  • Silent fill provides a gracious experience by filling the tank quietly

Featuring multiple fill rate inserts, the Kohler fill valve helps to optimize tank filling performance and water conservation through tried-and-true methods. No matter the model or size of your toilet tank, the adjustable valve system works to accommodate any height, yet is most compatible with Kohler toilets.

The new models of the Kohler valve extend to nearly 14 inches from the inside of the tank, simply by twisting the threaded gray valve stem. With color coded input and output stems, it is easier than ever to properly install the Kohler system simply by paying attention to the included manual.

The bottom line is that the new Kohler valve has an incredibly quiet fill due to how the valve slowly releases to let water flow into the tank. That’s right: no more unpleasant whirring, mechanical noises, or aggravating white noise after a standard flush.

Customers should keep in mind that the Kohler valve will not necessarily work with every make and model of toilet. In fact, the valve is most well-suited for use in Kohler brand toilets, which means it’s up to the user to determine if it will install properly in their own toilet.

Some users have complained that the allowable space of adjustment does not bring the water level high enough to flush in their own toilets. Additionally, the valve is non-refundable with no options for adding on a warranty.

Using water control assembly, the entire kit comes with the refill valve, shank washer, lock, and coupling nuts needed for installation.

According to satisfied buyers, this new valve model from the Fluidmaster brand helps to minimize old problems with whirring flushes and loud refills. With smooth function, low cost, and durable parts, you can’t go wrong with the Fluidmaster 400A – in fact, customers even get replacement coupling nuts and tubing in case any of the major components wear down.
