A How-To Guide On Changing Your Reverse Osmosis System Filters

A reverse osmosis system is a type of water purification system that uses a semipermeable membrane to remove contaminants from water. However, to keep the system working properly, you need to change the filters regularly. Here are the basic steps to change the filters on your reverse osmosis system.

Step 1: Turn off the water supply

Locate the water supply valve that connects to your reverse osmosis system and turn it off. If you have a storage tank, locate the tank valve and turn it off as well. If your water purification system is connected to your refrigerator or ice maker, locate the valve that connects to them and turn that off too.

Step 2 Drain water line

Turn on the faucet that is connected to your reverse osmosis system and let the water run until it stops. This will drain the water from the water filtration system and release the pressure. You can also open the faucet of your refrigerator or ice maker if they are connected to your system.

Step 3 Remove the old filters

Place a bucket or a towel under the filter housings to catch any water that may drip. Use a filter wrench or your hand to unscrew the filter housings and remove the old filters. Dispose of the old filters properly. You can recycle some of the filters if they are made of biodegradable materials.

Step 4 Clean the filter housings

Remove the O-rings from the filter housings and inspect them for any cracks or damage. If they are worn out, replace them with new ones. You can buy new O-rings from your local hardware store or online. Clean the inside of the filter housings with soap and water, and rinse them well. You can also soak them in vinegar for 15 minutes to remove any mineral deposits or bacteria. Dry the filter housings with a towel or a paper towel.

Step 5 Lubricate the O-rings

Apply a thin layer of O-ring lubricant or food-grade silicone grease to the O-rings. This will help to create a tight seal and prevent leaks. Do not use petroleum-based lubricants, as they can damage the O-rings and the plastic parts of your system. Reinstall the O-rings to the filter housings.

Step 6 Install the new filters

Insert the new filters into the filter housings according to the instructions of your trusted provider of water treatment services in Mesa, AZ. Make sure to align the filters correctly and do not over-tighten them. 

Step 7: Turn water supply back on

If you have a storage tank, turn on the tank valve as well. If your system is connected to your refrigerator or ice maker, turn on the valve that connects to them too. Check for any leaks and tighten the connections if needed.

Step 8: Flush the system 

Turn on the faucet that is connected to your reverse osmosis system and let the water run for 10 to 15 minutes. This will flush out any air and carbon fines from the system. You can also turn on the faucet of your refrigerator or ice maker if they are connected to your system. The water may look cloudy or have a slight color at first, but this is normal and will clear up after a few minutes. Do not drink the water during this time, as it may contain some contaminants from the new filters.

The frequency of changing the filters on your reverse osmosis or water softener system depends on several factors, such as the water quality, the water usage, and the type and model of your system. However, as a general rule, you should change the sediment filter every 6 to 12 months, the carbon filter every 6 to 9 months, the reverse osmosis membrane every 24 months, and the post-filter every 12 months.

By changing the filters regularly, you can ensure the optimal performance and longevity of your reverse osmosis system, as well as the quality and taste of your water. Contact Gold Star Plumbing & Drain if you need any help with changing the filters on your reverse osmosis system.
