I have a Kent Float valve mounted 3/4 up in a Rubbermade garbage can. Almost a year now, Never had an issue. We'll turn the RO on when the can is low and leave it for 1-2 days. I don;t think you will have a problem with the Fresh water. How many humidifiers have you heard about flooding? replace the float valve every couple-5 years just to be safe, because the seal will wear out, just like the taps in your home.
Now, using it direct in a sump, possible Salt Creep and such, That's a different story.

Only thing is you do not want your RO/DI direct to a float valve, as it will cause excessive wear and ultimately premature failure of the RO membrane. Instead, feed the valve off a bucket reservoir that you only fill once empty. That's what I do anyhow.

Yeah I have 2 float valves wired to a sprinkler valve for my tank ATO. And I also have the sprinkler valve on a timer so it only has power for 2 min 6 times a day. So It has a fair amount of protection. If the first float fails then I have the second and if it fails too then hopefully full water for 12 min a day won't flood the tank before I notice.
The humidifier float is just for my water changing. Like sphelps said, just a safety mechanism in case I forget that I'm filling the can while watching tv or something. I assumed that they were pretty reliable if they're used in humidifiers but I wasn't sure if maybe humidifiers had another safety mechanism that I was unaware off? And I wasn't sure how often these need replaced / have problems but it doesn't sound like anyone has had any?

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.

But again, I'm not really understanding the RO Auto shut-off? Once the little R/O pressure tank fills doesn't the unit always shut off?

Oh ok I think I under stand the confusion. I didn't just add it straight to the R/O outlet... I t-ed it into the regular supply line (after the pressure tank)

I wouldn't trust my float 100% either, I put a ball valve before the float so I'm only filling the container when needed. The float itself is more of a safety switch so I don't flood the place if I forget to turn off the valve.

But yes, now that he says he has a Pressure tank RO, he allready has a shutoff installed on the RO system.
