New to RODI

After consulting your linked schematic, and BRS's install video, I think I see the problem. I installed my check valve after the auto shutoff valve. I would have thought that it would work anywhere inline on the clean water line. But now I see that has no way of stopping the waste water {slaps forehead}
Thank you for the info.
I am off to tear it down. Wish me luck

Thanks hillegom !
It takes a full 100 seconds, but it shuts off now. And thats at 60psi.
The system did not come with a check valve or float switch, so I can only blame me. But I must say even if it came with these items, with the instructions that were included, I probably could have pooched the install anyway.
I'm still proud of what I have done. I wanted the ability to monitor the TDS of the Raw, RO and DI water, use or not use the DI canister, and monitor both the Raw and Filtered water pressure.
Objective complete ... continue with suds

Right on!
auto shut off is good
