FAQ

When to Change Reverse Osmosis Membrane?

It is typically recommended that you change your reverse osmosis membrane every 24 to 36 months.

However, this may vary depending on the specific water treatment system you have and the quality of your water supply.

If you notice a decrease in the quality of your pure water, it may be time to replace the membrane.

You can also refer to your owner’s manual for specific instructions on how to change your RO water membrane.

How to increase the life of the Reverse Osmosis Membrane?

There are a few things that you can do to help increase the life of your reverse osmosis membrane.

First, be sure to only use filtered water in your system.

If you allow unfiltered water to enter the membrane, it will quickly wear down and require replacement.

You should also flush the membrane regularly with purified water to help remove any built-up sediment or contaminants.

Additionally, it is important to keep the storage tank full of water.

If the tank runs low, it will cause the membrane to work harder and eventually wear out.

How do check Reverse Osmosis membrane is damaged?

If you think that your reverse osmosis membrane may be damaged, there are a few things that you can do to test it.

First, disconnect the tubing from the membrane housing and pour a glass of water.

If the water is cloudy or has bad taste, the membrane is likely damaged and needs replacement.

You can also check the pressure gauge on your RO unit.

If the water pressure is low, it may indicate that the membrane is not functioning properly.

If you are unsure whether or not the membrane is weak, it is always best to consult with a professional.

It will be able to properly diagnose the problem and recommend the best course of action.
