I didn't get a chance to turn the water back on for the RODI unit to see if my latest attempt worked. I'll do it tonight
I picked up an end cap to replace the one on my manifold that is leaking. I cut it off this morning and will replace it tonight. It is the worst of the leaks... other than the union that was missing the "O" ring which I also picked up. The others are small... 1 or 2 drops a minute. The owner of the lfs where I bought the tank (who also builds and maintains big systems) has told me that small leaks like that will seal up with salt water.
