Knowing that direct feed from the RO/DI into the sump is dangerous I found this item on BRS that seems triply redundant. Has a flapper valve, float valve and solenoid. Plus you can hook it up to a timer to only fill at designated intervals. Has anyone tried this? http://www.bulkreefsupply.com/store/level-loc-auto-top-off-unit-for-ro-systems.html
