Humidifier Float Valve

[banditpowdercoat]

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
