Humidifier Float Valve

[mark]

living on the edge here.

I have a furnace humidifier float valve in my sump connected directly to my ro/di for a ATO for the last 4-5 years, zero problems.

What let's me sleep is there's many more furnaces out there than fish tanks and in all my years never come across it myself or heard from someone their basement flooded due the humidifier. I've had a problem once on a old furnace with the valve not opening from deposits. Figure here I'm running about 2g a day of ro/di through it, it's flushing itself.

Now would not use one on a kalk drip system.
