I have a 100g DT with appx 120g of total volume. I placed the RO and 34g brute can in the basement. I purchased the ATK V2 because the apex videos convinced me on the 3 layers of redundancy. I’ll also have the ATK connected to an apex classic. My concern ofcourse is a pmup fail which stays on and 34 gallons of fresh RO coming upstairs. Am I safe?? Should I go with a smaller ATO container??
