Watermaker issue

[MV TurningPoint]

One quick question and I’m afraid I already know the answer....
I have a DIY system with two new Dow 2540 membranes. Upon replacement I can’t get good product water after running for an hour. I only have a conductivity meter and it’s pegged.
All I can figure is I messed up an O ring installing the membranes?

TIA

Is there any chance you are dumping the good water and testing the bypass water, maybe an error in reassembly?

Can you test product off each membrane separately?

I did replumb almost everything adding a more compact control panel. I will recheck my work .

Great suggestion about isolating each membrane for testing! Back ASAP with those results.

Thx

Great solution!
One membrane is OK , the other one, not OK.
Thank you for cutting my job in half!

PS. We’re all geared up (almost)for Desolation Sound.
When are you opening that border?

I wanted to report a happy ending to this saga.
One membrane had a pinched O ring in the end cap.
So this was resolved for $1.59
Luckily I work cheap

Thanks for the help.
