How Often to Replace a Reverse Osmosis Tank

Reverse osmosis tanks are used in homes to purify water. A reverse osmosis system is comprised of a membrane, tank, filters, and pump. The membrane removes impurities from the water by using a process called reverse osmosis.

The frequency for replacing your RO tank will depend on how much you use your system and the water quality in your area.

The RO Tank

The frequency for replacing your RO tank will depend on how much you use your system and the water quality in your area. If you live in an area with hard water, it’s recommended to replace the system every 6 to 12 months. Soft water areas will need to replace their RO tanks every 18 to 36 months.

How Often to Replace a RO Tank?

The frequency for replacing your RO tank will also depend on how often you use it. If the membrane is clean, the system will purify water more efficiently. When you start to notice a reduction in your water pressure or water flow, it may be time for a new tank. As I mentioned above, replace your tank every 6-12 months if you live in an area with hard water, if soft water, replace your RO tanks every 18-36 months.

If you live in an area with hard water, you’ll need to replace your RO tank more often than someone with soft water. Hard water contains minerals like calcium and magnesium which can clog the pores of membranes, leading to decreased efficiency.

Cost of Replacing an RO Tank

The cost to replace an RO tank can range from $400 to $1,000. The frequency for replacing your RO tank will depend on how much you use your system and the water quality in your area. If you have a system that produces 10 gallons of water per day, the lifespan is about 2-3 years.

The cost of replacement filters will vary based on the type of filter you buy. The most basic filters are priced at about $17, but if you want better quality water, more filters are needed which will increase the price.

How Long Does a Reverse Osmosis Tank Last?

It really depends on how often you use your system and the quality of water in your area. The average lifespan of a RO tank is 5 years, but this can change depending on the frequency of use.

For example, if you are using your system everyday for 6 months out of the year, you should expect to replace your RO tank every 3 years. This is because the membrane will deteriorate quickly by being used so frequently, whereas if it’s only used for 3 months out of the year, it might last closer to 5 years.

If you find that your membrane is deteriorating faster than expected or you are noticing that the pressure in the system has dropped significantly, then it may be time to replace your RO tank.

How To Maintain Your Reverse Osmosis System

How often should I drain my reverse osmosis tank?

A reverse osmosis tank should be drained at least once per year, but the frequency is dependent on the quality of your water and how much you use your system.

Do reverse osmosis systems need maintenance?

Reverse osmosis tanks are not maintenance-free. The system needs to be checked for leaks, changes in water levels, or if there are any issues with the membrane.

Most manufacturers recommend that you change your filter every 6-12 months, depending on how often you use your reverse osmosis system.

You should also measure the level of water in your tank periodically to avoid overflow or getting caught in a situation where the reverse osmosis system is shut off due to lack of water in the tank.

Is it necessary to sanitize reverse osmosis system?

When your RO system is not in use, it’s important to keep it clean.

The tanks may contain bacteria and other organisms that can be detrimental to your health. Cleaning the tank will help to remove these organisms. You should also sanitize the RO system every few months, even if you’re using it regularly.

Cleaning your filter is one way you can do this. Filling up your tank with vinegar or baking soda and letting the mixture sit overnight is another way to sanitize your system.

If you want to make sure that your RO system stays sanitized, there are products on the market designed to kill bacteria and other microorganisms in water systems like reverse osmosis filters.
