If you’ve ever had a toilet that won’t stop running or has a weak flush, chances are you have tried to fix it by jiggling the toilet handle or removing the tank top to tinker with the rubber flapper. These are only short-term fixes; the bigger problem at hand is probably a fill valve needing to be replaced as soon as possible.

A toilet fill valve is responsible for refilling your toilet tank after being flushed. This can get worn out over time, causing leaks and other performance issues. Luckily, replacing a valve is pretty simple, and definitely more affordable than a full toilet replacement.

The experts at Toiletable are here to help you better understand everything you need to know regarding toilet valves. We’ll talk you through the basic differences, how to replace a flush valve, as well as some of our favorites on the market right now.

Types of Fill Valves for Toilets

Fill valves are possibly the most important part of the typical gravity flush toilet found in most homes.

Keeping track of the differences can be tricky but we’ve simplified the process. Take a look at our guide to fill valves down below.

★ Plunger Fill Valves

Plungers are one of the earliest fill valve designs. Plungers work with a floating ball attached to a pivoting lever, which opens and closes to let the water out.

They are usually made with a heavy-duty brass body and function relatively quietly.

If you have a fill valve such as Mansfield 09, you should replace it because it is not anti-siphon and doesn’t meet current plumbing codes.

★ Ballcock with Brass Body

These types of fill valves have also been around for a long time. The main difference between these valves and plungers is that this option is anti-siphon, which meets the plumbing code.

An anti-siphon valve is installed to prevent the backflow of contaminated water into the clean water source.

Diaphragm-type ballcocks come in a brass body and have a diaphragm that opens and closes to control water flow.

★ Ballcock with Plastic Body

Essentially the same as other diaphragm-type ballcocks, these options are made from plastic, which is more common in newer models.

This is what you should be looking for if you want to upgrade or replace a ballcock-type fill valve with another ballcock.

★ Float Cup Fill Valve

The float-cup fill valve is considered to be a more modern solution. The first model was introduced in the 1950s by Fluidmaster. It has a floating O-shaped cup instead of a ball, and is attached to a metal spring clipped to a rod.

The water level is controlled by adjusting the position where the rod connects to the cup.

These valves are very popular and easy to maintain, making them an excellent choice.

★ Float-less Fill Valve

This type of fill valve is a new innovation, made of plastic. They don’t require a floating ball or cup to work. They have a diaphragm pressure-sensing mechanism, originally designed for low-profile toilet tanks in the 90s.

These fill valves are affordable, and since they have few moving parts they are very durable and reliable.

They operate underwater, and you will usually find them attached to the bottom of the tank.

This technology allows you to choose the amount of water used per flush, which helps save up to 70% of water consumption.

The HYR270 features a two-button setting. One button is for the quick-flush setting which uses significantly lower volumes of water for smaller waste loads while the second button is for the full-flush setting.

Fill Valve Buying Guide

Buying the right fill valve can be quite tricky. There are a few things that you should keep in mind, so in this section, we will talk about everything related to buying the right fill valve for your toilet.

Ease of Installation

One of the first things that you should consider, especially if you are not a DIY professional, is ease of installation. Thankfully, most fill valves are relatively easy to install, and the fitting of most brands is more or less the same. For example, you would be able to fit a Toto fill valve in a Kohler toilet with no problems.

Further, most fill valves come with a useful user manual that guides you through the installation step by step. The key steps in the process are setting the required height, fixing the valve in the tank, testing the valve, and making any final adjustments.

One-Button vs. Two-Button Valves

This choice depends mainly on the type of toilet you’ll be using with the valve. For example, two-button valves are not a top priority for modern houses. However, these are a good choice for cabins, RVs, and other situations where the supply of water is limited.

Adjustability

Buying a valve from the store is simple. You can walk into a store with a sample of a piece that you want to replace and they will give you exactly the same model. However, buying a fill valve online can be tricky. If you’re planning to make your purchase online, you might want to buy a valve that is adjustable, to be sure that it will fit your toilet.

Compatibility

As mentioned, most fill valves are universal, but not all. Different models come in different sizes and shapes, so make sure to get the right description and dimensions that match your toilet model before you buy. Also, check if you should buy a valve that is singular or dual-flush.

Low Water Inlet Holes

A nice advantage of a fill valve with low water inlet holes is that it consumes less water without compromising the performance. This factor might not seem like a big deal, but you will notice quite a difference after a month’s use.

Noise Insulator

No one wants to hear any noise that comes from the bathroom. To promote comfort and privacy, modern valves are designed with sound insulation that minimizes any noise. If you notice that your toilet flushes with noise, it could mean that the valve has worn out.

Refill Rate

The refill rate is the time it takes for the toilet to refill after a flush. This detail is important because it directly affects how long another person has to wait after the previous person has used the toilet. It might not be of great importance for small families, but a quick refill rate is important for larger families and public bathrooms.

Water Intake

Another factor you may want to consider is the water intake adjustability caps or a roller clamp. These features allow you to adjust the water intake, which prevents having to store up large volumes of water after every flush.

How to Replace a Toilet Fill Valve

Replacing a toilet valve is easier than it seems. These simple steps will help you replace your valve in no time!

  • Disconnect your water supply line. In the back of your toilet, you’ll see the water supply valve. To turn it off, turn it clockwise. Don’t forget to flush in order to drain the water from the tank.
  • Unlock the old fill valve. Depending on your fill valve, you’ll need pliers or a wrench to remove the valve nut. After removing the nut, pull the valve towards you and lift.
  • Insert the new valve. Insert the fill valve shank into the fill valve. Push down and tighten the nut.
  • Adjust the refill tube and adjust the water level. Reattach the refill tube and angle adaptor to the overflow pipe holder.
  • Adjust the water level. Turn your water supply line on by turning it counterclockwise. You can adjust the water level by pressing on the adjustment clip and moving it up or down.
