130 is still on the high side IME, but then again, I don't own a Vertex. I have my house PRV tweaked to give me around 110 psi at the tap and my second psi gauge plumbed in after prefilter & carbon, before RO membrane usually gets me to 90 psi. Most membranes are rated with a given water temp & pressure, I think most of them are tested at 60-70 psi to provide the gpd rating. Not sure what the burst limit is, but I'm fairly certain anything over 100 is getting risky. See last FAQ on the page linked below:

Again, I don't own a Vertex, sure seems like 3 solenoids would make things much more complex. Had a look at your photos & almost impossible to troubleshoot something like this with all that plumbing running behind the cartridges. But I did notice the T fitting at the front of your prefilter and that makes no sense to me?

Any instructions come with the unit? If not, contacting the good people at Vertex may be your best bet for a solution to the issue.
