I’m planning on building a stand in my garage to hold a brute up top and one underneath. The top one will store RODI. My tank is about 60 feet from this. Id like to have a length of RODI tubing that I keep rolled up in the garage to reach the tank to fill up my ato container. Can this be gravity fed or do I need to find some sort of pump to convert to 1/4” or 3/8” rodi?
