How To Replace Apec (ROES-PH75) Reverse Osmosis Filters and Membrane - Stage 1-6 

Man, this was a super helpful guide for the changing of the filters. It made my life so much easier just now with my filter replacement! Thanks so much!

Hey man 2 years later and this video is still helpful. Thank you for taking the time to make this!

I wasn't comfortable changing these filters out. So naturally I RU-vidd it and found your video. Nicely done and step by step. Thank you for doing this.

Thank you for making this! Being a visual learner, the instructions weren't super clear, but having this as an aid made it so much easier!

Thank you for making this video for DIYers! You made it so easy and I ❤️ the 'lefty loosey' tips and the cute pumpkin bucket. You've demystified a seemingly overwhelming process. 👏🏽👏🏽👏🏽

Good job on this video! I am prepping to make my first 5 filter replacement. Your video clarifies the written instructions and allows me to be more confident I will be successful. Thank you!!!

Thanks for explaining in detail. You made it look so easy. I will re watch your video before I replace all my filters as soon as the replacement filters arrive this week. Also glad you reminded me to buy O rings as well.

Very well done. I would offer a few tweaks. Every 2 or 3 years or so, you need to do a super-duper clean, i.e., you never know what kind of mold or bacteria is lurking; therefore, I would add a step in there that includes a diluted bleach solution. On mine, I took off all the housings for stages 1 - 4, put them in the sink, and scrubbed them with soapy hot water. I know they said don’t unhook the tubing to stage 4 membrane housing; however, disconnecting the tubing is really the only way to really clean that membrane housing (mine was a little funky inside). They probably just thought people would forget how it was all hooked up; so I took pics along the way. I used a pair of rubber-coated tongs and a wad of paper towels, since I didn’t have a good long scrubber and scrubbed the insides. Then I rinsed. Then I filled all 4 housings about 60 to 70% full with hot water and then filled them up the rest of the way with bleach; I mixed it up and let it sit there, upright, in the sink for 5 or 10 minutes. Note: you have to plug the holes for the stage 4 membrane filter housing for it to hold water (you can use the plugs that come with the new filters). I also used this as an opportunity to apply some bleach solution to the t-fitting of the new stage 5 carbon filter t-connector (the one that comes with a t-connector attached), as instructed. Then, after about 5 - 10 minutes of wet time, I rinsed everything really well (like rinsing for 10 good minutes, cumulatively, for all 4 housings). I also put the metal frame of the assembly, turned it upside down, and put it in the sink, and did a similar soap & water scrub, plus bleach decontamination with the top of the housing that the stage 1 through 2 housings screw onto. Note: this cleaning process was most necessary for the stage 1 filter as it will always be the dirtiest. But I like the idea of doing a thorough cleaning on everything every 2 to 3 years. Also of note: I think when they say don’t touch the 4th stage membrane, they are assuming our pliers are cleaner than our hands. I’m down with using some pliers to remove the membrane; however, I know where my pliers have been; therefore, I chose to put the new membrane in by grabbing it with a paper towel (instead of pliers, to avoid touching it with my hands or pliers, while still keeping it as sterile as possible. Note; every few years, I would say change the stages 1 - 3, O-rings (not sure if you can buy the stage 4 O-rings but it wouldn’t hurt if you can find them). But in between those 2 - 3 year intervals, if you are changing them every 6 to 12 months, probably just a fresh thin coat of plumbers grease (Vaseline) is sufficient, after cleaning them thoroughly. I do like to waste 3 tanks of water before using, albeit, the 3rd tank is likely overkill. By the way, I had the ROES-PH75 for 4 or 5 years. I upgraded, recently, to the "APEC Water Systems Ultimate RO-Hi Top Tier Supreme Certified High Output Fast Flow" and also purchased the "APEC Water Systems PHPLUSKIT-38" kit. Both purchases were just a few bucks more than the ROES-PH75. It gives you the exact configuration as the ROES-PH75 but it adds in the 3/8 tubing and connections which allows for a faster water flow out of the faucet. You should put some Amazon aff links to this upgrade in your description. My dream setup: eventually, I want to run the stock APEC 4 gallon tank and APEC's 20-gallon tanks in random (for crazy pressure and capacity), if I ever get a place with a convenient garage or basement location to put the 20-gallon tank. Actually, in a perfect world, I would put the filters assembly and the tanks in a garage or basement, just in case, there is ever a leak; and then I would just have feeder lines coming into 2 or 3 faucets in the house and the fridge. That’s my 2 cents:) Best!

Great video. I like how you showed on camera all the steps we need to take, especially with all the tubes we needed to disconnect and connect.

So glad I saved this to a water filter folder in my play list so I can get a refresher when I need to change it again. Thanks for your video

Of all the APEC System Filter Replacement videos I’ve watched (7 Total!!), your’s contains more preps/ideas/things to know BEFORE you go through this procedure, along with ideas to make this task more enjoyable [rather than a disaster!]. I truly Thank YOU for making & posting this video - Kudos!!!🇺🇸

Thank you! I was a bit afraid to change the filters but I felt very confident after watching your video!

Thank you for taking the time to make an in depth, fully detailed video: great job! Cheers

Thanks for this video. Mine is side-mounted and hard to get access to the top of, which makes it much harder to change Stage 4s. I hope more plumbers can install them in a way that makes them easier to move around and work with like here! It helped a lot to see someone do it.

Thanks Man. I was a little reluctant (scared) to tackle this job. You gave me the confidence to move ahead.

Tip for those tight screw on connections, put a small amount of Vaseline on the threads. This tip was included in the housing instructions for both my whole house filter and my countertop filter. Makes unscrewing them way easier.

Sir, thanks for taking the time to make this, it's super helpful. I really appreciate it!

Nice job- thank you for your thoughtful, step-by-step coverage. It was appreciated.

Thanks, this was my first filter change and this video was super helpful and really appreciated!

This guide was very helpful. The APEC system is easy to use and maintain. Great product!

Its my first time to change our drinking water filter, with your video i manage to change the 1-3 stage filter. Thank you for sharing this video.❤

Great video. Thank you. I was stuck in the installation process and that helped me to get the job done Thanks

Very helpful indeed! Followed the video step by step to replace my APEC filter stages.

Very impressive, you made a very detailed, helpful,and informative video. APEC should give you a lifetime of filters for a job well done, Thank You

Thank you very much for doing this video! House we bought came with one of these and this video helped out greatly! It sure made this a LOT easier! Thanks again!! :)

Very helpful video. Thanks. The only thing which I found helpful from other videos which is different in this one is that one can remove all 3 stage filter container at once and then install them all together rather than doing it one by one.

Thank you for sharing this great instructional video. I'm getting ready to order my replacement filters and I feel confident that I can do it myself.

Great job!... Complete in every detail. Thank you!

I like how the tank is tucked behind the piping. Really saves you some room.

Without you I couldn't take away that white wire from filters. Thank you for helping me

Best video ever! You should do this four a living on all products!

Very helpful! Truly appreciated. I saved a lot of time because of your video

Thank you! It did help me in replacing the filters.

This was VERY helpful. Thank you!!!

Very helpful presentation brother. Made my life easy. Followed your instructions step by step. Thanks for your help.

Because of your video, my wife is demanding I change out the filters in Apec. Next is changing filters on our pelican Water conditioning system, after that Hansing saltless water softener. After that vacuum the house, after that go grocery shopping together, after that water the lawn, after that I die on this Saturday. Thanks.

Thank you so much for this video so helpful. I had the same problem with the membrane cannot get it loose. Need to wait for someone to help me too! OMG.

Thank you for the excellent video. I really appreciate how detailed you were and how well you explained what you were doing. Also, thanks for shooting it so that I could see every step. I don’t know what brand my system is because it came with my house, like yours, but it has no brand name on it. However, the connections look basically the same as yours so I think I could use the filters you did. I only have a five stage but I think it will be fine. Thank you again.

I just changed out all my filters all by myself after watching your video again. THANK YOU SO MUCH FOR THIS VIDEO!!! It was so helpful! My system was a little different because the stage 5 doesn't come with a new T junction. I am supposed to use the old one. I think my system is older than yours. Thanks again!

Thanks for the step by step video, very helpful

Good video. I have the same system and love it!!! I am 1 yr into using this system and looked for instructional vids and yours came up the best for this process. Good job!!!

Just got this system thanks for the info🤙

Omg thank you so very much. Perfect explanation…better than Apec 🎯thank you ❤

This is so helpful! Thank you!

Thanks--this really helped!

Thanks for this... very helpful!

Thank you so much! I'm so grateful for this video. 🙏

Really helpful! Thanks so much.

For PH75 systems, Stage 4 & 5 need to be changed out once 2-4 years For PH90 systems, Stage 4 & 5 need to be changed out once 3-5 years Our system is the PH75, so it should be 2-4 years, the photos I took were from a PH90 system, sorry about the confusion!

So helpful. Thank you so much!

thank you for this excellent video....I think I can do this now!

Very Helpful, Friend ! Thank you.

great video. thanks for your hard work!

Thank you so much Man ! I really appreciate this video. You made it easy. God Bless

thank you so much. excellent tutorial. just what I needed.

Excellent video!!!

Wow never seen one that bad. Thanks for posting.

Thank you so much for making this video

Thank You! Great Job ! 👍👍👍. I love this system Apec

I thought I would need a plumber until I found you and your video. Thank you for sharing and caring!

Thanks for this video. Appreciated.

This video was sooo helpful. Thank you so much! The written directions were not as good as you!

I really enjoy your video, was very well explained

It was very helpful review for me, big thanks. Just one thing, please, remove that outlet from the sink at least 5 ft away and make it GFCI. ) thanks for help

awesome work, thanks for your help

Great video dude

Great video! Clear step by step instructions on how to do a full swap out. One question: did anyone go through this, turn their system back on and notice that the water flow was a bit slow - and choppy? I can't tell if this is a normal part of the break-in period for new filters or something else. FWIW, I don't see any leaks in any of the systems. Any advice is appreciated!

Helpful. Thank you.

Great video. I would suggest using two strap wrenches for the membrane.

Nice video thanks

Thank you

Thank you!!!

great video

Thanks so much!!!

Thanks!

You made it so easy to change these filters! Now my only issue is I can’t open the membrane lol

Very helpful...thank you

Thank you for making the video. Just to double check... The Alkaline filter takes the water from the tank and then goes directly to the faucet?

Hi! Did you ever try to flush the filter with tank closed? If so ..did you have slow running water or few drops...? Thanks!

Excellent video and tips. I couldn't unscrew the membrane though 😂 it's so tight.

Wow, that filter is nasty! This is very helpful when in the future I decide to install one and replace it. Thanks for sharing!

Thanks .

Thank you for this, a much needed video that APEC didn't even have for this particular model! For the O-rings, do we switch out every year or 2-4 yrs? And we need just 3, correct? And do you have a link on Amazon for this? I can't seem to find it. Thanks in advance!

Hi, I like your informative video, one question, please explain why is my red tube discharge water is keeping leaking, thank you

i have the ET6500gro will these filters work on mine. please advise. Thank you

super excellent

Any tips on how to get the really tight cap off of the membrane housing? We’re using the tool it came with, and we have two people, and it’s still not budging.

Mine didnt come with a new T on Stage 5. Should I still bleach my existing T before replacing it?

always run water thru the sed and the carbon before you run it thru the membrane, you can expel a lot of carbon fines that would end up in the membrane, and also put a bypass on the flow restrictor and clean your membrane ever 2 or 3 weeks, you will love the results

So quick question- I noticed your first stage is the finer filter - shouldn't this go last so the larger filters pick up the larger objects first?

Does anyone know what the TDS of this filter is supposed to read once you change it? I noticed it was 90-100 total dissolved solids. I know there is a final “remineralization” stage, but I didn’t think it would read that high.

Great video! Could you please let me know where I can find the serial number on this item? I have the UV version and they have a different replacement depending on the serial number and I can't find it anywhere. Thanks!

How do you cycle a tank of water? How do you know the water is good to drink?

Great work! When you say empty out the tank, is that with the cold water on or off? Or will it not drain without the cold water being on?

This was a great video. Really helped my wife and I. We ended up emptying the the tank before finding your video. Now we have followed the steps you showed (we only replaced the three bottom filters ) and the water seems to drip out. Do we need to wait for the tank to fill? Is this a pressure issue?

Excellent video. I am researching the APEC RO. Are you still happy with your unit and does it still maintain the clean flow rate?

Thank you for this! I need to change out all my filters for the RO-90 system, and I was feeling a little overwhelmed. Do you know how to tell if you have a quick dispense upgrade or not?? I need to order the Stage 4 and 5 filters and I can't figure that out!! Also, how do you know that you've let the tank empty for 1-2 complete cycles? No more water comes out from the filtered water faucet?

السلام عليكم. شكرآ على المحتوى. .. ما هي. اسماء المراحل بع. اللمبرين والغاية من تركيبها. شكرا..

I have a Apec RO90 Reverse Osmosis system it has a 4 gallon tank. In the manual it says it takes about 2-3hours to fill the tank. I noticed faucet never stops, water trickles endlessly after 1 hour. Is this normal? wouldnt faucet stop after the tank is emptied since it takes a while to fill the tank/filter water?

hey so i messed up a little. i had the stage 4 tubbing and stage 5 mixed around. i had the cross thing hooked to the stage 4 instead of 5 like you do. did that ruin the filters? should i just get new filters?
