Eating Up RO Membranes

[Woodyman]

Agreed. Wasn't sure if I should go sediment to carbon but I follow your way.

It honestly shouldn't make a difference but I'd polish down to your 1 micron prior to carbon just as an added precaution

How long was the membrane prior to the last 3 installed for? 1 year, 2 year, 3 year, etc?

Not sure but would be unfair to say as the unit had been taken down and put in storage for a couple years

Gotcha, I'm assuming you weren't going through them every 3 months before you put it in storage?

 

[flyfisher2]

I can say that the setup has been like this for the last year and that I've replaced all the filters several times in that period

Noooo.... Just can't honestly give you a time frame. They did last considerably longer but then again usage was probably less? I'm guessing here

Gotcha did you re-plumb anything when removing it from storage. I didn't realize you had the unit in storage. However if nothing was re-plumbed from when you originally put it away to when you took it out, it shouldn't be a plumbing issue.

I added the three canisters with additional DI. And replaced the restrictor. I tried the 100 and went back to 75.

Gotcha, I'm assuming you have double checked your restrictor install?

You did plumb your RO and not Brine water waste to your DI canisters right..!? ;):p

Did you see the video?
I think I got it right
God knows I looked at multiple schematics on how to do it

Yes I watched it, it was a good walkthrough and everything looks setup properly, and it appears your flow restrictor is the quick connect type not capillary so you can't really hook those up wrong unless you set them backwards.

While by no means a requirement, I like to color code all my tubing it makes spoting any incorrectly set lines easier.

I use black for my feed line, yellow for my filtered (sediment/carbon) water, red for my brine waste water, and blue for my RO/DI. I wish I had a fifth for the DI instead of blue being used for both RO and RO/DI

Just a few maintenance tips if you haven’t done already.
1 New membranes get flushed for an hour

when you connect the membrane does it look like this one with the waste line off to the side and the ro a bit off center.

One more thing from your video, personally I would move the booster pump from the hose connection to after your sediment/carbon, this way you get it boosted up to ~80psi for the RO membrane. Instead of boosting it for sediment/carbon and losing some of that pressure to the filters.

 

[flyfisher2]

Yes The waste line is the one furthest from center and I verified that at install by taking TDS readings from both lines
If you read previous post I was getting about 5TDS post Membrane

Didn’t think of that. The videos show it installed at the beginning

It can be done either, but lower pressure on the sediment and carbon won't lower your production or efficiency quite like it does on an RO membrane.

I ordered all new lines and I’m set
Had a roll of black at the time and that’s what I used

It's a small thing but it really helps when quickly glancing at the system to tell what's what throughout the process

I made a video of mine For you to look over but for some reason I can’t upload from my iPhone
