        Buyer’s Guide

        Searching for the best toilet fill valve for your toilet can be a difficult task. While it may be tempting to opt for the first toilet fill valve that you discover, you will need to bear a few things in mind first.

        Most importantly, you will need to ensure that your chosen fill valve is actually suitable for use with your particular toilet. Otherwise you could have just wasted your money!

        We’ve collated all of our essential research criteria in a helpful buyer’s guide. This should help to give you all the information you need to know before you commit to buying a new fill valve for your toilet. As long as you’ve considered the below information, you can rest assured that you’re making a fully informed decision.

        Take a look at everything you need to know about toilet fill valves below, or skip ahead to the frequently asked questions!

        Universal design

        When it comes to choosing the best fill valve for your toilet, you should opt for a model that features a universal design. This should then allow you to adjust the height of the valve itself so that it can suit a variety of toilet heights. You also won’t have to stress that you’ve wasted money on a fill valve you can’t use!

        If you’re still not sure that your chosen fill valve is compatible with your particular toilet, you can always consult with your local plumber. They should be able to advise you on which is the right model to get for your particular toilet.

        Easy to install

        You will of course want to opt for a fill valve that is super easy to install. These can be installed by yourself, and you won’t have to pay your local plumber a fee to come and do the job for you. You should ensure that your chosen fill valve comes with all the hardware components that you will need to replace your broken fill valve.

        Another important factor to bear in mind is whether your fill valve comes with a full set of instructions. These should be able to help you through the process to get your new fill valve installed.

        Flow or refill rate:

        The time that the toilet tank takes to refill once you flush is what we call the refill rate. If your toilet has a fast flow and refill rate that means you will use the toilet soon after a flush. The feature is very useful, especially for those living in large households with many people.

        Durable

        The fill valve in your toilet will naturally start to wear away over time. The longest that it will last you is for between 4 to 5 years. So you will want to choose a fill valve that has been made using durable, long lasting materials so that it will last you for as long as possible.

        This will be particularly important if you live in an area with hard water. This can wear away at the elements of your fill valve quicker, especially if poor quality parts have been used. You should opt for a fill valve that has used better quality materials so that it will last you longer. We’d recommend opting for long lasting components such as chlorazone red rubber.

        Noise

        Another factor to consider is the level of noise you want from your chosen toilet fill valve. Some people may be tempted to opt for the cheap and cheerful options, however, you should bear in mind that this might mean you have to put up with a noisy fill valve.

        If noise is something that’s going to bother you each time you head to the bathroom, then you should opt for a quieter fill valve. This will be able to do the job quietly, so you’re less likely to notice it each time you have to walk around the house near the bathroom.

        Height adjusting features:

        You need to measure the height of your toilet tank is essential when looking for the right fit. Many modern fill valves are easy to adjust, but you should check the height limits on the description. If you measure the tank before heading to the store, you will have confidence in your device.

        Efficient

        If you’re conscious of your water bill or your carbon footprint, you should opt for a fill valve that is highly efficient. This will help you to optimize the performance of your toilet and will save you from wasting any unnecessary water. 

        You should also look for a fill valve that allows you to adjust the fill rate of your tank. This will work to make your toilet more efficient, and ensure that no water is wasted.

        Multipacks

        If you have a toilet that’s tricky to find parts for, it might be worth considering choosing a model of fill valve that comes in multipacks. This way you can buy more than one fill valve, and keep the spare ready for when your next fill valve will need to be replaced in a few years’ time.
