Humidifier Float Valve

[banditpowdercoat]

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.

FWIW I use them in my sumps .. don't really have a problem with salt creep because the freshwater coming out flushes any away. About once a year I'll take them apart and blow out any dust or whatnot.

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.
