Humidifier Float Valve

[superduperwesman]

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)

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.

what does not make sence? I think I'm being clear? I made last post before I seen his last ones

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

You do not have to have a tank in your RO system to have an auto shut off valve (ASOV)
Most systems come with this valve so that the unit shuts itself off and does not make any more ro water nor any more water to the drain.
Here is a link, for a picture, there are a lot of pics on the web.

Oh ok... thanks. I'll look for this when I get home... like I said. I don't actually have it all plumbed in yet I was just trying the float valve out on the R/O supply line that I ran. I'm gonna pick up my R/O from my old place this weekend.

No extra protection on the humidifiers and if you think about it household pressure is anywhere from 50 to 100psi typically.. think the biggest problem tends to be calcium buildup over time.

Most of it, but don't take it personally. All RO units should have an auto shut off unless they are the portable units which are only hocked up to a water source when needed. I wouldn't say that's the norm most units are permanently hooked up to a water source and the shut off valve is on the output. This being the case it will require an auto shut off whether a pressure storage tank is used or not.

The basic rule is to never rely on mechanical floats. I believe humidifiers have a drain if the water level gets too high, same as a toilet. Electronic systems can be designed with unlimited safety systems to prevent failure so you actually design them to meet your own personal confidence level.

Most older humidifiers have a float valve and pan to hold water, the only drain is the one on the floor when it overflows. The mechanical float valves on these units last for years without fail. In my previous house the float valve had been working for 11 years and had not spilled a drop. The key to these things is simplicity. In my current humidifier I have an electronic solenoid and it took three of them before I got one that worked properly. I don't know of too many electronic devices, especially ones controlling water, that I would trust for 10+ years.

Well, I have just seen more of the temp hookup style RO units in this hobby than the permanent, drinking water kind.
