View Full Version : Connections correct?

I am wondering if these connections are correct. I looked at your manuals online but am still uncertain.

Ok, one last question and I will leave you be. I just replaced the membrane along with all of the filters (do not have the DI filter in yet while flushing out the membrane). I have all kinds of waste water, but no dip-dip of pure water as of yet. Is that because of the filters being flushed out? Or because I do not have the DI cartridge in?
Thank you so much for your time!

It's not because you don't have the DI in, but I have to ask where the water came from that is in the DI housing. It surely came from the RO membrane, so the system is probably working.
Did you remove the flow restrictor that is inside the yellow waste tubing? That would keep the system from making good water while letting all the water go down the drain.

The flow restrictor is in. I remember when I first got the unit (some 6 years ago I believe) I had to cut the restrictor quite a bit. Perhaps it is time for a new one?
(forgive the fuzzy picture)

Flow restrictors don't wear out. Although, in six years, your house pressure may have dropped for any number of reasons - you haven't moved recently, have you? Yours looks to be of a typical length, not TOO short.
At this point, I would need to know, after running for 20 minutes, the product water flow rate and waste water flow rate in milliliters per minute. Also what size membrane do you have?

I have moved recently! From Northern Cali to here in Las Vegas. This is the first time setting it up since the move. :) I have tested to see how much psi I am pushing though the unit. 50psi. Too much?
I can run the unit for 20 minutes and see how well I can measure the amount. The membrane is a TFC 25 GPD.
Thank you again Scott. I really appreciate your help.

50 psi is fine.

Well I ran it for a good 20 minutes and measured the pure water to the waste water. In one minute I would get 900 ml of waste water, and would not have enough to measure (would start at 50 ml) of pure water. Maybe 4-5 drops. :(
I must have something very wrong.

Now, I have enough information. The clues are:
1. You have adequate pressure.
2. Just replaced the membrane.
3. Flow restrictor is in place.
4. Hugh amounts of waste water and only drops of product.
You did not push the new membrane in far enough.
Take the membrane completely out of the housing.
Inspect the far end with the stem and two o-rings. Be sure they are not damaged or ill-fitting. Re-insert the membrane, pushing FIRMLY until it won't go in any further. That should do it.
Let me know,

Awesome Scott. I'll go do that right now! :D

Well hot damn we have success! :D Good amount of waste water, but a steady drip of pure water.
Tested the TDS of the pure water, very high still. That is because the membrane is being flushed? I was not sure if I should keep the RO filters in while I do that.
Thank you so much!!
