Help with water changes, ATO and patience :)

what if ATO fails and you flood your tank with RO water?

Also the frequent start stops on the ATO are not always good for it.

I use one of the generic rubbermaid blue bins with a Kent float valve drilled into the top, and a 1/4" hose to another Kent float in my tank. Been going this way for a year now with no issues.

I have a double float on my ATO. If the first one fails for any reason, the 2nd one higher up, will stop the flow entirely.

Is that the only concern? I was wondering if the RO/DI water needed to be aged or something before going directly into the sump, similar to when mixing salt water prior to a water change.

I plumb my RO directly to my sump. I use a float valve, with a pressure switch inline. I also run it through a solenoid that only turns on 15 minutes every four hours. My RO unit does about 3.5 gallons in 90 minutes, which is about my evaporation for the day, so I could go a few days at least with a blown float system.
1 year on this system so far.
