I currently have RODI entering my 3 gallon ATO reservoir via 1/4" line. I fill it up by opening a valve and setting a timer on my phone so I don't forget to turn it off. ATO water enters my sump via gravity fed 1/4" line hooked up to a manual float. I would like to automate the ATO filling process, and add a way to purge my RO membrane on start up. I do not have a controller (apex, hydros etc), and dont plan on getting one
From what I understand this can be done in several ways, but I want to get yall's advice. My preferred way would be to use high and low level optical sensors that control a solenoid valve (inline with my RODI) to fill the ATO, with a mechanical fail safe (float valve?) for the high level so I dont have a flood. I'm not worried about flooding my sump on the outlet-it can handle about 20 gallons of extra water.
Is there a kit out there for this? Maybe an ATO I can modify? Can I just buy some sensors and a solenoid and a float? Would I need to plug it all in to a controller of some sort?
As for purging the RO on startup, I'm not sure how to do that. My RODI filter is in the basement and the tank is upstairs. Routing anything from one floor to the next is not something I want to do. Is there some kind of flow-sensitive timer do-hickey that could route the startup water down the drain?
