Browse the DIY forum threads for water auto-change & drip systems, there are different methods covering various approaches to it.This thread is making me re-think how I am going to set up an auto water changer. I've always wondered how people dechlor their tap water with an AWC, but a lot of them use RO to do this on their water feed. So would it be best to use tap with an AWC and just dump in a chemical dechlor every once and a while, split the feed water to run 50% RO 50% tap and use no dechlor?
