Do you want to save money for your family by changing your own Reverse Osmosis filters? RO systems look complex, but it can’t be all that difficult? These filter housings look like they can be easily opened but how do you disconnect the tubing? How do you know when to change reverse osmosis filters anyway? I’m going to explain when and how to change filters in RO system, right now!
As I’m sure you know, Reverse Osmosis Drinking Water Systems are perfect for your family if you’re looking for an inexpensive source of "super pure" drinking water for your home. For a Reverse-Osmosis system to continue to operate flawlessly it needs to be maintained by replacing the filters and when needed the membrane. If your not sure how these systems work, I’ve got a great video here • HOW does a REVERSE OSM...
Most families of 2-4 people need to replace their filters annually and the membrane when needed, this video talks about filter replacement only, I’ve got another great video on membrane replacement here • How to REPLACE the MEM...
If your water contains a high amount of sediment, it may be necessary to change the 1st stage cartridge more frequently. If your water contains a high amount of chlorine, it may be necessary to change the 2nd stage pre-filter more often.
If you’re planning on disinfecting your Reverse Osmosis drinking water system, this RU-vid video of mine shows you how as you would complete that before putting in the new filters • HOW to CLEAN RO System
If you’re not sure which replacement filters you need check out this video • HOW to FIND and ORDER ... or go to our website waterestore.ca/collections/re...
1. Turn off incoming water supply and valve on the storage tank. Place a tray under the system to catch any water that spills during removal of the filter housings.
2. Open faucet to release pressure.
3. Unscrew bottom of filter housings from caps. Use the filter wrench. Discard used cartridges. I like to do this one at a time to minimize the chance of mixing up the filters.
4. Remove black rubber O-rings from grooves in housings. Wipe grooves and O-rings clean; set O-rings aside.
5. Wash out housings and rinse thoroughly.
6. Lubricate each O-ring with a coating of clean silicone grease. With two fingers, press each O-ring securely into groove below the threads of the appropriate housing. CAUTION: The rubber O-ring provides the water-tight seal between the cap and the bottom of the housing. It is important that the O-ring be properly seated in the groove below the threads of the housing or a water leak could occur.
7. Insert cartridges in the bottom of the housings. Make sure cartridge slips over standpipe in the bottom of the housing.
8. Screw bottoms of housings back onto caps securely; do not over-tighten.
4th Stage Post-Filter Cartridge: post-filter should be replaced every twelve months.
1. Remove filter from bracket and remove tubes from fittings by pressing in collar around the fitting while pulling the tubing out with your other hand.
2. Check out this video about using quick connect fittings • How to use Quick Conne...
3. NOTE: If quick connect fittings need to be installed, tape threads of fittings with 3 wraps of plumber tape and attach to filter. NOTE: The filter has an arrow on it showing the direction of flow. The tee fitting connects to the inlet side of the filter and the elbow fitting attaches to the outlet side. NOTE: Hand tighten fittings, then tighten with wrench 1/4 turn.
4. Attach 4th stage filter to bracket with the tee fitting on the right hand side.
5. Attach tubes to fittings by pushing in until the tube stops. Check to see if tube is in place by trying to gently pull tube out Turn on cold water supply. Check for leaks. Continue to check periodically to make sure no leaks develop.

Changing Reverse Osmosis system filters is easy, check out this video to learn how!

@rbrown6476 2 года назад

Ah man - that was so so helpful! For ten years, I’ve had a reverse osmosis system and paid a guy to change the filters for me. I’ve decided to have a go and bought all the filters. Now I’ve watched this incredibly useful, clear and patient video, I feel confident to make a start. I think you’ve covered all the basics, all the possible problems that might arise and then some great tips about towels and flushing the system before drinking. I can’t tell you how thankful I am! Keep up the good work. I wish there were more men like you, who don’t make it complicated so as to appear clever and then tease the person who wants to try for themself! Respect to all modest men who are teaching us how to be good citizens, with kindness.

Gary, I am so grateful for your videos. My filter system is almost 10-years old and the filters had never been replaced. (Long story involving a renter who installed them but passed away before he could do or teach me the maintenance and then I never found anyone who could do it.) Anyway, your video is great and now I’m no longer intimidated by the system. I’ll be able to do it regularly and by myself. (I also had to re-pressurize the system and your other video taught me how to do that.)

Can you please tell me what kind of connector is that? I see it is size 3/8 and has a hex screw with a tubing that goes to the T connector and had threads on the other. TIA

Just followed your video and changed my filters. Great video , especially that they were very difficult to get off. My problem is there is only 3 seconds of water running from the tap, then nothing. It was doing this before I changed the filters and thought it was because of old filters.

@GarytheWaterGuy 2 года назад

Gary, I have an R/O system where the second filter is called an AACT, which stands for All About Contact Time. It would be the stage 2 on your 5 stage R/O system. I can't seem to find the part number to re-order. Which filter do you use in your second stage? I will just use what you recommend.

Hi Gary … thanks for the many videos on RO systems. I just changed out my filters and membrane (75 gpd rating) and flushed the system 3 times. I then measured the TDS against a distilled water standard (0 ppm). My water supply to the RO system contains TDS = 150 ppm and RO water measures TDS = 50 ppm. You mentioned in one of the videos that one should see a 90% reduction in TDS. So I was hoping to be in the 15 to 20 ppm range on the RO water. I will continue to monitor the TDS after a few more system flushes. My question to you is … do RO membranes have a design/performance limit regarding TDS removal? My new membrane is an Aqua Flo membrane - Model 1812 - 75 -NPI. My system is a Canature 475 with (one sediment and two carbon filters. No polishing filter). Thanks in advance for your feedback. 😊

@GarytheWaterGuy Год назад

Yes but your water is within the range. I suggest you flush a few more times and check over the installation. If it doesn’t improve see about getting a replacement membrane

@JimQChang 2 года назад

Hi Gary, thanks for all these very helpful videos. I replaced all five filters (including the membrane) in my 5-stage RO system about a month ago. I flushed the filters as you suggest. My tap water has a TDS of around 650. The water from the RO tank has a TDS of around 100. However, if I shut off the tank and let the filtered water drip, the TDS can get as low as 25. I have tested this several times and the results are consistent. I was thinking that perhaps the pressure from the tank might be reducing the effectiveness of the membrane, but air pressure is correct at 7 psi when the tank is empty. Any idea what might be going on and what I can do to fix it?

@GarytheWaterGuy 2 года назад

I would try changing the flow restrictor to wee if that helps.

@amylancaster5535 Год назад

Thanks for the easy to understand videos! I just changed out the filters for the first time after about 9 months of use. The sediment filter looked completely new when I removed it. I expected it to look dirty or dingy. Should I be concerned it's not working properly or I just wasted time and money swapping these out too soon?

@GarytheWaterGuy Год назад

No, you just learned that in the future you can go 12 months before changing the filter.

@sallers791 Месяц назад

Thank you for your video. I was stuck on removing the tubing from the post carbon filter. The written instructions didn't do it for me, your video is a big help. My system also says to sanitize with bleach, which I have done with the two large filter housings at the bottom (I don't have 3), but not sure how to disconnect the tube to the tank to add bleach there. Do you have a video showing that?

Hello Gary! Hoping you can help me figure this out...We’re in AZ and have hard water. I recently replaced all 5 of my RO system filters (including membrane) about 3 weeks ago and flushed the system for about an hour. Filters were 1.5 years old, membrane at least 2 years old if not more, and I immediately noticed the flow dramatically increased. I just bought a TDS meter today and checked our tap water level (740), bottled spring water level (30) but the RO water level is super high (1585). I haven’t been able to find any help online, do you have any suggestions? Any ideas are much appreciated, thank you!!!

@GarytheWaterGuy 3 года назад

You need to flush the membrane longer. they come with a preservative which will elevate the TDS. You need to fill and empty the tank at least 3 times, which typically means flushing for about 10 hours.

@iron6634 9 месяцев назад

I have seen other video's on changing filters on similar systems and they said to not install the RO membrane until you have flushed out the carbon filter, otherwise it will ruin the RO membrane....makes sense to me.

@GarytheWaterGuy 9 месяцев назад

I have performed these filter chnages hundreds of times in customers homes and since the membrane is typically only changed every 5-7 years but the carbon and other filters are changed annually we do not remove the membrane during the filter replacement unless we are replacing the membrane. I have never had a problem with the carbon fines "ruining" the membrane or have ever heard of it happening to someone else. It wouldn't hurt to do it that way, just not necessary.

Hello, I've searched all over the internet, and see the same informationm but can't seem to find the order and type of filters that go in a 5 stage home system. Stage 1 is a PP-5 micron filter, Stage Stage 4 is the RO membrane, Stage 5 is post RO activated carbon (I believe it's typically labeled as T33?). What about stage 2 and 3? What is the difference between a CTO (carbon block filter) and a UFD (granulated carbon filter)? Do you mix two types together, or use the same?

It smells like rubber, like it might be the bladder inside the tank. Obviously I don't drink it, but I run water through it for maybe 5 or 10 minutes, then the odor goes away.
