Setup RO/DI on a timer
 

I want to fill my RO/DI storage tank on certain time of day. Can I do that with a Orbit lawn sprinkler valve hook up to my aquarium controller and a float valve to turn it off when full.

I'm sure you can. Only issue is you can't perform flushes automatically before and after, or bleed off the initial high tds water from the membrane on startup. Basically you'll rip through resin faster.

Thank you Lastlight.
