Home reverse osmosis system maintenance (simple steps to do at home)

The reverse osmosis system lasts for 10-15 years if it is properly maintained. To help your RO system last longer and work effectively here are step by step for home reverse osmosis system maintenance.

Reverse osmosis system maintenance

Reverse osmosis system maintenance checklist

  • Replace sediment filter every 12 months
  • Replace carbon block filter every 6 to 12 months
  • Replace RO membrane every 2 to 3 years
  • Replace polishing filter every 6 to 12 months
  • Drain RO storage tank every 2 weeks
  • Clean and sanitize the RO system every year
  • Check storage tank pressure

Simple step by step to follow at home

  1. Replacing the filter at the right time

An ordinary reverse osmosis system operates in 4 stages. Each stage uses a different filter that requires to be changed after a period of treating water. The common stages include

Sediment filter– this is the first stage of the RO system. A sediment filter is designed to filter out sediment, sand, silt, and dirt. This protects particulate from getting to the Ro membrane that can clog easily.

The sediment filter requires to be changed every 12 months if you fail to replace it at the right time particulate can reach the membrane then get easily clogged.

Carbon block filter: carbon filters include granular activated carbon (GAC) and carbon block.

Carbon block is the second stage of the Ro system. It is designed to remove contaminants such as chlorine taste and odor, organic chemicals (pesticides, herbicides, and insecticides), THMs like chloroform, and volatile organic compounds (VOCs) (that include gasoline, solvents, and industrial cleaners).

The carbon block filter lasts for 6-12 months. The range depends on the contaminants in your water and household usage. The more the contaminants the less the duration.

Granular activated carbon is the fourth stage (will discuss below)

Reverse osmosis membrane: this is the heart of the RO system and third stage. The Ro membrane lasts for 2 to 3 years.

The range depends on how you maintain both sediment and carbon filter. If you replace both sediment and carbon filter at the right time the RO membrane will last longer

RO membrane is designed to remove contaminants such as

Granular activated carbon: This the fourth stage of the RO system.

Granular activated carbon is designed for polishing. It helps remove any extra taste and odor in the water

Granular activated carbon lasts for 6 to 12 months.

Failure to replace the filter at the right time will cause your RO system to produce less water and more water wastage leading to a high water bill.

  1. Draining the storage tank

Drain the water in the storage tank every two weeks. Draining water ensures you have fresh water and help the RO membrane maintain the optimal pressure required.

Since the under sink reverse osmosis system takes time to refill it is advisable to drain the tank before going to bed. This gives time for the tank to refill.

You can use water to clean or water plants.

  1. Cleaning and sanitizing the reverse osmosis system

Cleaning and sanitizing the RO system is done annually when you are replacing the filters.

This helps remove germs, dirt, and bacteria in the reverse osmosis storage tank, housing filter, and reverse osmosis faucet.

  1. Check storage tank pressure

The empty reverse osmosis storage tank has a pressure of 7-8psi. You can use a pressure gauge to measure your RO system storage tank. In a year the tank may lose 1 psi if you find your tank under pressurized use a bicycle pump to add the required pressure

Repeat the process once every year.

Above is a common process used in the ordinary reverse osmosis system. If you are not sure about the process you can consult your RO system owner or check on your system owner manual for detailed instruction.

How long does a reverse osmosis system last?

If well maintained reverse osmosis system last for 10-15 years

How often should the reverse osmosis membrane be changed?

Reverse osmosis membrane should be changed between 2 to 3 years this depend on your water quality and household usage

How do I know if my RO membrane needs replacing?

If the system is producing less water and more water is going to drain it’s time to replace the RO membrane.
