How To Care for Your Reverse Osmosis System – RO Maintenance Tips

Reverse osmosis is a filtering process that uses pressure to force water across a semi selective membrane under conditions of higher than atmospheric pressure. This is the process by which most residential, commercial, and industrial water supplies are treated. However, it’s important to maintain your home or office reverse osmosis system properly to avoid problems and keep your water clean.


Do Reverse Osmosis Systems Need Maintenance?

Reverse osmosis systems are fairly easy to maintain and rarely need any major attention. However, there are a few things you can do to help keep your system running smoothly.

First, make sure that your membrane is clean and free of debris. You may have to run a filter through your system if it’s been clogged with dirt or other particles that can build up on the membrane. This will ensure that the filter does its job properly and filters out any bacteria or other contaminants from the water for drinking use.

Next, make sure your system is pre-filtered before it enters the storage tank. Even though you may be using a reverse osmosis system, some contaminants still can get in. If you don’t pre-filter before entering the tank, these contaminants could build up inside of it and create problems later on down the line when they enter your drinking water supply. It’s important to make sure that these contaminants don’t get into your drinking water supply so the filter can take care of them before they reach a point where they become a problem.

Finally, make sure that your system is properly maintained. You should keep an eye on the amount of water you have stored in your tank, as well as the amount of water you’re using. If the storage tank runs out, you may have to turn off your filtration system until more water is added to it. It’s also important to change out your filter regularly. Depending on how often you use your system, a new filter may be needed every few months or even more frequently.

Taking care of these three things will go a long way toward keeping your reverse osmosis system in good shape and ensuring that it continues working properly for many years to come.

Here are some tips for caring for your reverse osmosis system properly.

Know What Type of System You Have

Before caring for your RO system, you should determine which type of system you have.

You have a home reverse osmosis system when it is located inside the home, apartment, or office where water is treated and then used by people in the building.

You have an office-based (or commercial) reverse osmosis system when it’s used at a business or place of work.

If you don’t know what type of system you have, call your water provider or search online to find out.

Maintain the Proper Pressure in Your System

The pressure in your home or office is one of the most important things to maintain. If the pressure in your system falls too low, it can cause problems with the performance and efficiency of the system. It’s important to check your water pressures regularly to make sure that they are at their optimal levels.

One way you can do this is by having a gauge on your reverse osmosis system. This gauge will let you know if your home or office is producing enough pressure for good performance and efficiency.

Another good way to check for proper pressure is by using a hydrometer. The hydrometer will show you if there’s any salt in the water. When a certain amount of salt is present, the water will have a specific density that will not allow it to produce good pressure through its semi selective membrane.

To properly care for your reverse osmosis system, make sure that it has enough pressure so that it produces quality results and lasts as long as possible.

Monitor and Adjust Your pH Levels

The best way to care for your reverse osmosis system is to maintain proper pH levels. It’s important to monitor the pH of your water before it reaches the RO membrane and after it leaves the RO membrane. You should also adjust your pH level if necessary.

One of the most important things you should check on a regular basis is your initial water pH level. When you first hook up your new reverse osmosis system, test the water pH levels with a meter and make sure they are between 5.0-7.0 depending on what type of filter you have installed in your home or office. If your water isn’t within that range, adjust it accordingly by adding household bleach or sodium hydroxide (a common chemical used in lye) to lower the pH level until it is in that range.

Flush the System Regularly

Flushing the system is a good way to keep your water clean and free of contaminants. It’s also important to flush the system at different intervals, depending on how often you use it. For instance, you should flush the system every time you run a load of laundry or use your dishwasher, but you shouldn’t need to do it more than once a month.

Another thing you can do to help keep your reverse osmosis safe is properly maintaining the temperature in your home or office. Keep the system between 50°F and 100°F during operation and always be sure that all components are covered with condensation free plastic wrap.

Clean and Maintain Your Filters

Filters should be replaced every six months, but they can be cleaned more frequently. It’s important to clean the filters to avoid problems such as:

  • A reduction in water pressure
  • A decrease in water quality
  • The membrane becoming blocked and restricting flow

The best way to clean a filter is with a vacuum cleaner. For this, you will need a brush attachment or some other form of cleaning tool that can reach into all of the crevices. If it is difficult to reach the bottom of your filter, use liquid detergent and a toothbrush, making sure not to get detergent in the membrane.

Protect Against Back Flow

One of the most important features of a reverse osmosis system is that it prevents back flow. However, if you don’t protect your system against backflow, you could cause problems with your whole water supply. Your reverse osmosis system will stop working if the pressure from the incoming water is greater than the pressure of your outlet water. To avoid this, you should make sure to have screens or valves that prevent backflow on all four sides of your pipes.

How Often Should I Drain My Reverse Osmosis Tank?

It’s important to drain your system every few months, to make sure all the sediment from the water has been removed. Otherwise, this sediment will build up and could possibly block the membrane, reducing the effectiveness of your reverse osmosis filtration system.

Make sure you have a bucket or tub with a small opening that can fit inside your system. You’ll be able to remove any sediment that is still in your system.

How Long Does a Reverse Osmosis System Last?

Your reverse osmosis system should last for at least four to six years and even longer if you maintain it properly. If you’re not sure how long your system has been in use, it may be helpful to keep a log of the changes in your water quality.
