It is challenging to give an average as it will vary depending on size and other factors, but a good range would be between $40 and $80 for a standard 4 to 6-gallon RO tank that fits under your sink.
This is almost impossible when it comes to giving an average value. 20-gallon tanks could be around $200, and 165-gallon tanks could sit at $600, and that is not taking into account factors such as brand and materials.
There are various factors that influence the cost of an RO storage tank. Some may be important to you, and some may not, but they are all important to know about and consider.
Smaller RO system tanks, such as under sink models, will have a significantly smaller price tag than whole house RO tanks due to the variation in size. Usually, an under sink reverse osmosis system will have a 4 or 6-gallon tank, but they could be bigger, which will increase the price point. So, it is essential to consider the size of the RO system that your household needs, and the water output, so that you don’t needlessly overspend.
You can find some RO tanks made from plastic and not metal, which will be cheaper, but not as high quality. If the materials used to build the tank are FDA-approved, they will likely be more expensive, too, as you are paying for the quality and security.
Is the tank NSF certified? If this is the case, it will likely be a bit more expensive. NSF certifications ensure that the item you purchase has been quality-tested to guarantee it does the job it is supposed to do and is not a risk to your health. The more NSF certifications your RO system has overall, the more expensive it will be.
While the brand may not equal quality with any product, the more well-known brands are probably going to be more costly than the lesser-known ones.
You get what you pay for. If the overall quality of your RO tank is poor, you will be paying less than you would with a well-put-together, high-quality tank.
If you have a whole house or commercial system, this may be a factor for you. Pressurized tanks are usually much more expensive than atmospheric tanks of the same capacity.
For example, the 165-gallon atmospheric storage tank by Crystal Quest listed above comes in at $590.00, while Pentek’s pressurized tank of a mere 120 gallons costs $1,790.00.
Keep in mind, though, that an atmospheric tank will also require the installation of a delivery pump, which will come at an extra cost.
The best place to buy an RO tank is online, as you can check out so many different online stores and tanks, plus benefit from factory pricing for the retailers that do not have a storefront to pay for.
Amazon also has a large selection, with the advantage of being able to check out customer reviews for the product too.
You can visit a local retailer, and this may be beneficial if you want to chat face-to-face with an expert, but the prices will likely be higher.
