Humidifier Float Valve

[hillegom]

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.

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.

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?

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
