Humidifier Float Valve
 

Bought one of these last night b/c I'd like to start mixing my water in advance. That way I can do a few water changes before having to mix some up again. I can give it lots of time to get up to temp and I can go watch TV while I let a few weeks of water accumulate from the R/O system (once I go pick it up from my old place and install it ahah)

But so far it seems to work great and the price was even better (around $8). Anyone ever have a bad experience with one?

You just put it on the RO line? Did you add in the Shutoff valving for the RO unit Inlet? Can't just put a float on the RO outlet because the inlet will still have water pressure and you will be just pushing water out the waste line.

If you turn off the inlet water when it comes full, then that is OK, but as long as you know, without a float shutoff valve, whenever water is supplied to the RO unit, Waste IS being made, regardless if RO is being made or not

just dont trust it 100%... their good for this application but don't leave the house when its in use.


yea i agree with the post above.. do you have a Auto shut off on the RO unit?

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.

I'm confused? Assuming I had no float valve and I was just using the R/O for drinking water... so what happens at the R/O tap on my sink? Am I suppose to shut of the inlet to the R/O system every time I'm not filling a glass of water?

I have a shut off on the line that I t-ed to the mixing tank just as an extra precaution for the twoish weeks that I'm not making water but again I fail to see how the float switch doesn't simulate pretty standard operation?

Yeah, I won't 100% trust in which is why I have the valve as an extra precaution.

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)

Ohh you have a RO unit with the pressure tank, then you should allready have a shut off valve. basic RO/DI units like most reefers have do not have the shutoff incorporated as they do not have a pressure tank.

This is what I am refering to

Your RO has an auto shut off, just ignore that post. It doesn't make sense to me either.

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.
