Auto Top Off
 

I picked up a humidifier float for 10 bucks at home hardware with the intension of making an auto top off direct from the RO/DI. When the float drops, a rubber seal is opened up and water flows out. When the float moves up, it closes the seal. I thought about salt blocking it, but the fresh water should wash any salt away.
Has anyone set anything like this up? Any problems that you can think of?

Cheers,

Make sure you have one of thesehttp://www.jlaquatics.com/cgi-bin/sh...gno=ro-kpfshut And you may want to add an inline timer allowing only as much water as is needed per day before the RO unit. Otherwise in the event of a tank leak, you could be filling your tank with fresh water constantly. Or until you notice the leak. :eek:

That's what I use on my 65g top up container hooked up to my system. I have used the cheep float vlaves for many years and the work great!

I used a cheap plastic float in my sump, just gravity feed though for freshwater, no problems that I ever found.

Ditto what Jonathan and Doug said. But ditto also what Chris said, if you're going to hook the RO/DI unit right inline with it, you want some kind of shutoff (solenoid) on the inlet side of the RO/DI unit so that it's only on when it has to be. :biggrin:

Auto Shut Off
 

You bet guys,
I have the Aqua-Safe RO/DI and it already has the auto shut off.
