Your RO or RO/DI unit...did you know?

[atcguy]

I was told thats units shouldnt be run all the time. They need to stay running for 15 minutes or more ... ie to keep a resevoir filled by a float valve.. So now my controller tells me every 4 days to run my ro unit and top my resevoir up. Doing this allows the unit to run for 2 hrs to fill my container opposed to on off on off throughout the day.. Works for me
