Humidifier Float Valve

[viperfish]

I have a humidifier float valve installed in an 80 gallon Canadian Tire Rain Barrell. It works flawlessly. I get enough water to do changes in all of my tanks at once if I need to. I have no valve and the thing has not failed me in over a year. I do have an auto shut off on my RO/DI system. I currently have my RO/DI supplying water to my 180, 90, 33, 20, and w/c barrell all at once, and all with humidifier float valves. I just fill my w/c barrell at night so i can keep the other resivoirs full for my ATO's.
