Gravity ATO from the mixing station - through the attic....

[Fasthandsslowmind]

Due to the small ATO reservoir in my stand and my distrust of small pumps, I plan to set up a gravity feed ATO with a float valve + solenoid. The mixing station with my RO water is in the garage, a few feet above the tank elevation. However, there's no way to run the line below the floor, so it'll have to be ran into the garage ceiling, through the attic, then down to the tank.


Has anyone successfully done this in a siphon configuration? My concern is that the float valve or push-to-connect fittings will allow the siphon to be broken, but I'm not sure if that'd actually happen.

Advice?

Thanks!!!!

If this was my setup, I'd run a ATO pump in the garage to the tank instead (something like a Neptune PMUP).
