What to Look for Before Buying?

When choosing a fill valve for your toilet, there are usually three things that you are looking to solve. They include a weak flush, leaky valves, or a noisy filling. In that case, it is important to choose the perfect fill valve for your toilet. Here are some factors you should consider when finding one;

The Plunger/Ballcock Type

A plunger or ballcock is an old type of fill valve that comes with a float ball and brass arm. It will feature a brass that is sealed off with a rubber washer, which is then affixed with a ballcock valve. If this system breaks down, you will only have to buy a new rubber washer to fix it.

Here are other types of the valve to consider

1. Floatless Ballcock

This is also known as the cupless style valve, and it can sense the water level from the bottom of the tank through the diaphragm. It is easy to use and can be set up by turning a screw at the top of the valve. This is the best choice for low-profile tanks.

2. Diaphragm

This is a valve that is mostly made of plastic, and it has a ball and float arm similar to the plunger valve. But, fixing a diaphragm style valve can be difficult. However, they are cheap to buy.

3. Cut Type

This is also known as the container type valve that happens to be the most recent style. Most new toilets will come with a cut type valve. The size is adjustable, which means it can be used in almost any tank out there. Most of the units we reviewed are container-type valves.

Compatibility

The first reason for purchasing the valve is to use it in your toilet tank. So, you must ensure that the valve fits comfortably in your toilet tank. Make sure to check the height and dimensions of the valve and if it is generally compatible with your toilet.

Construction/Material Used

Most valves are made of plastic or rubber, and you should choose one that is strong enough to serve you for a long time. You should ensure that you choose one made of high-quality rubber and ABS material. It should also be corrosion and bacteria resistant.

Noise

Does the fill valve make noise when the toilet tank is refilling? Ideally, it should be quiet enough. If possible, let the seller test it for you before-hand.
