I am redoing my tank and have run a ro line from my garage to the tank so I don’t need to have a ato reservoir under the stand anymore or the tunze auto top off pump system anymore. I am using a 40 gallon tank as a sump with no partitions in it. Just open from side to side. I need to figure out a way to hook up a float valve in the sump to control the top off. Any ideas?
