DI will mess with the metal though?? Bummer. Was hoping to get away with it....


Heres some gogle info I'm finding.

Well, it'll probably be OK if there's no DI sitting on the metal constantly, but I'm the paranoid type and wouldn't do it with my own system. I'd just get a big ass brute trash can for your ATO resevoir and refill manually as needed. Saves on a catastrophic RO/DI failure when a float valve sticks (or something like that) which seems uncomfortably common among reefers.

There's not going to be a catastrophic failure. See, the Automation of things is my Job. Failure is NOT an option. But, some of the solenoids will have RO/DI in them at all times so that leaves the metal out...
