TDS creep and automation

[PYRU]

I would like to be to leave my system on 24/7 with shutoffs in place. I've looked around and can't locate a solution.

I used a manual valve to save my resin in the past, but is there an automated way of doing this? Diverter valve on a timer or sensor?

Have you talked to the guys at Bulk Reef Supply? I've found them to be extremely helpful with RODI system configuration questions.
