The Toilet Flush Valve Buying Guide

If your toilet is broken or there is a leak, it can be sourced back to a number of reasons. The most common cause is that your valve is broken. You will need to replace the valve to restore proper functioning of the toilet.

You can take it for professional repairing services, or you can use a spare toilet flush valve to do the job yourself. You can buy an appropriate toilet flush valve online or from the market so that you can install it. This method is convenient and will save you quite a bit of money. The market has many brands to choose from, and you are likely to be confused at first. To choose the best toilet flush valve for your house, you need to be aware of the different sizes and budgets that you can opt for. To make the selection process easier for you, we have narrowed down our top choices for toilet flush valves.

The Primary Types of Flush Valves

When you are buying a toilet flush valve, you should be aware of its different types so that you know which one you need.

Tank fill valve:

This is the most common kind of valve that can be found in almost all tank-style toilets. They come in two designs, namely the side-float design and also the concentric-float design. The former has been around for over a century while the latter is still relatively new. However, more and more people are beginning to prefer the concentric model over the side-float now.

The side float valve uses a ball-valve or a ballcock which was traditionally made with copper. Manufacturers have no shifted to plastic. The concentric-float fill valve has a tower that is surrounded by a plastic float assembly. Their method of operation is mostly the same. However, a concentric float valve makes it easier to detect leaks.

Flapper-flush valve:

Flapper-flush valves have become extremely popular now. The outlet is located at the bottom of the tank is covered with the help of buoyant flapper, and it is held in place by the water pressure. When flushing, the user pushes a lever which helps to lift the flush valve from its seat. You will even find dual flush versions of this model in the market today.

Flushometer valve:

A relatively new discovery, the "flushometer" style valve has proved to be a popular choice. You can find them in commercial restrooms where space is limited as these systems do not need a tank. You can identify a flushometer valve by its chrome pipe-work and the absence of a tank. There are different ways how you can go about it.

Features to look out for:

When you are buying a toilet flush valve, you should search for the following features.

Durability:

The toilet flush valve that you will be using should be made of strong and durable materials so that it can withstand the water pressure. Ideally, they should be resistant to corrosion to prevent rusting and weakening of the flush valve within just a few weeks. You do not want to be replacing your toilet flush valve frequently right? So you should focus on finding durable options when you know you have no other choice. Flush valves are usually made of different kinds of stretchy plastics which will stay put under pressure or specially crafted materials that are exclusive to companies.

Refill Rate:

Installing a slow toilet flush valve will not give you an edge over the last one that you are replacing. Efficiency should be one of your top priorities when you are looking for a new toilet flush valve. A fast refill rate will ensure that your water tank gets flushed with water faster. If you do not want to spend your time waiting for your tank to fill just because the flush valve cannot adapt to a higher speed, then you should go for one that offers a good refill speed. You will find the speed mentioned under specifications.

Noise elimination:

A good toilet flush valve will do its job silently. You do not need a toilet flush valve that creates a ruckus trying to fill the water. There are lots of flush valves available in the market today which completely eliminate noise. You will no longer be disturbed by the constant sound made by your toilet. These flush valves are excellent if you want a peaceful bathroom atmosphere. Older models still create a lot of noise, so look for newer models which come with advanced technologies.

Easy Installation:

In our busy lives, nobody has time to read up on valve installation and learn the process from scratch. All of us want to wing it once the package arrives. Hence it is important that you choose a toilet flush valve that can be easily installed. This is especially applicable for beginners who have never tried their hand at installing toilet flush valves before. There are a starter kits available in the market which come with all the tools you would need to complete the process. The better equipped a kit is, the faster your installation will go. You should find out if the toilet flush valve you chose comes with a comprehensive set of instructions.

Compatibility:

Sometimes we look for replacement parts for models that have been long outdated or which are not serviced anymore. In these circumstances, you will need a toilet flush valve that is compatible with different kinds of toilets so that you do not have to spend your money on a lot of valves trying to compare them. Toilet flush valves are offering universal fit work with most toilet models on the market. There are some companies which release toilet flush valves only for their own toilets. You can also purchase from them if you wish to, but check the details beforehand.

Adjustable height:

A good toilet flush valve should have an adjustable height so that the user can make the necessary changes. To make the fit perfect, the valve must be adjusted according to the size of the toilet tank. So it is best if the valve is flexible when it comes to installation. Having an adjustable height will allow it to be placed correctly and that will ensure efficiency. Most toilet flush valves have an adjustable height today, but you should check its features just to be safe.

Water Conservation:

You have a duty to the environment not to be wasteful. Water is a precious natural resource, and you should do your part in trying to conserve it. There are some toilet flush valves which come with the guarantee of saving water and being more earth-friendly than its competitors. You should ideally choose a flush valve that saves water so that you can do your part. These valves have been specially optimized to minimize the usage of water and still do a fantastic job. They will also allow you to adjust the water settings so that you can control it.

Warranty:

When you are purchasing a replacement toilet flush valve, it means that you are already repairing a broken toilet. To ensure that you do not have to do the same thing over and over again, you should look for flush valves that come with a warranty from the company. You can trust valves that fall under a warranty period because the company will take full responsibility if something goes wrong. If your new flush valve is not working or it arrives damaged, then you will be able to lodge a complaint and get a new one without any hassle. On the other hand, warranty-free products are bound to make you lose money.

Repair Kit:

Some toilet flush valves can be bought stand-alone, while others come in repair kits. You can invest in a repair kit if you are a first-time buyer because it will give you the tools you need to do this job again if the need arises. If you are purchasing the toilet flush valve online, you should check the contents of the kit under the description of the product before you actually buy it.

FAQs:

1. Should I get a professional to install the toilet flush valve?

A professional will always do a great job of installing the spare toilet flush valve and preventing any mistakes. However, most flush valves come with a set of instructions about the installation and can be DIY-ed if you so wish.

2. Which toilet flush valve is likely to last?

Some models like the Korky 528T Replacement TOTO Fill Valve-Fits are made with special materials like Chlorazone red rubber which can withstand water pressure and chemicals, and they will last you a long time. Otherwise, you can go for any toilet flush valve that is made of corrosion-free materials. Avoid toilet valves that have a lot of metal parts.
